Review
Veronica is a 5-Star Passion Ranger Combatant that hunts their enemies down from the backline whilst also offering amazing supporting capabilities.
Veronica delivers their damage via their Ballistas, which are unusable Attack Cards that activate themselves at the end of the turn for no cost. Her Ballistas are created from her Firing Preparation Upgrade card and can change the type of Ballista created via alternative Epiphanies to adjust how she delivers her damage.
Veronica can fill into an amazing support DPS thanks to having multiple different sources of low-cost Card Draw built into their kit from their Repose and Sir Kowalski cards, combined with the majority of her damage coming from her freely created Ballistas, can also dish out some great damage without needing any direct investment. As Veronica also comes with multiple upgrade cards, her deck can very quickly become an extremely small and consistent draw engine to help cycle through your deck as quickly as possible. Veronica can also boost her Ballista damage massively via the stackable Reload buff.
Because Veronica's Ballistas activate during the end phase and target enemies randomly, it can cause her damage to be quite random and if you aren't able to consistently stack her Reload buff, their damage can sometimes fall a little short.
Piloting Veronica effectively is relatively straightforward: create Ballistas, stack her Reload buff and support your team with her amazing Card Draw.
Veronica truly is one of the best supporting-DPS characters, with all of this taken into consideration and can almost fit into every single team with ease.
Phenomenal targeted Card Draw that can become even stronger with Epiphanies.
Consistently deals damage every turn with Ballista Cards at 0 AP cost after initial setup.
Upgrade-heavy card pool thins out deck size for other Combatants.
Impressive, mostly passive damage, assuming Reload is kept active.
Limited AoE - only accessible via Epiphanies and Ego Skill.
Ballistas target enemies randomly.
Optimal damage output relies on stacking Reload, which isn’t always easy
Upgrade-based strategy requires upfront AP investment to get going.
The ratings below are based on the Season Save Data, Chaos Manifestation, and Great Rift modes. Each of the modes values different mechanics, so some characters may shine in one of them, while being underwhelming in the other.
Ballista: Veronica’s main mechanic is Ballista cards. Ballistas are costless cards generated via her kit, which cannot be played and have the [Ephemeral] tag, meaning they’re exhausted automatically at the end of the turn. Before Exhausting, though, Ballista's deal a 150% ATK as Additional Attack damage to a random target. With Epiphanies, different variants of Ballistas can be generated that have different bonuses. Here is what they all do:
Ballista: Deals damage 150% ATK to a single target randomly
Piercing Ballista: Deals 200% ATK and also has piercing, which ignores enemy shields. Also deals +50% damage against shielded enemies.
Enhanced Ballista: Deals 200% ATK and also has +30% critical chance.
Giant Ballista: Deals the same 150% ATK but hits all enemies instead of one
Shelling Ballista: Deals 100% but hits twice instead, making it better at scaling with Flat +% damage scaling (like with Morale).
Micro Ballista: Deals 40% to a single random enemy (far weaker) but can be generated in higher amounts.
Reload: Reload is Veronica’s other core mechanic and is a stackable buff that can be checked either in the buff window or below the team HP gauge. Reload can stack up to 3 times baseline, with each stack offering a 50% multiplicative +%DMG increase to Ballista cards for the turn. Reload is gained via many of Veronica’s cards and all stacks of it will be removed fully at the end of the turn.
Note: Here is how the math works out for Reload at base. 150% x ( 1 + 50% x Reload Stacks). At 3 stacks, that’s 375% DMG.
Veronica’s Signature Potentials add new mechanics to her cards and all improve her damage, enhancing her Sub DPS capabilities.
3-1: Grants Rapid Fire a 20% chance to create a Random Ballista card on use. A must-have Potential if you plan to use Veronica’s Basic Attack at all.
5-1: Increases Rapid Fire’s DMG by +5% and an additional 5% if ATK exceeds 500.
7: Improves Ballista’s DMG by +5% while Veronica’s ATK is 700 or higher. Also adds an additional +1% for every 40 ATK over 700 Veronica, up to +10%.

Costs 5EP, deals a solid amount of piercing AoE damage and generates maximum Reload on use. A reasonable burst damage cooldown when factoring in the additional Ballista damage from Reload stacks. Use when Reload is inaccessible for the turn or when big AoE damage is required.
Rapid Fire
Attack
Veronica’s Basic Attacks can be upgraded with Potentials to gain a 20% chance to create a random Ballista on use, raising their value considerably to a point where genuinely using them is a fine option even in high-end decks.
Note: Random includes the baseline Ballista, as well as all the “Enhanced” versions.
Illusion of Golden Daffodils
Skill
Show Effects
Veronica's basic shield is completely standard and doesn't have any extra synergy with her kit.
Firing Preparation
Upgrade
Show Effects
A 1 AP Cost upgrade, which is the main way Veronica generates Ballistas. On use, it generates a standard Ballista, then generates another one at the start of each turn thereafter. This upgrade is the backbone of Veronica’s AP efficiency and damage before adding in her strongest Epiphanies. Also has the [Initiation] tag, ensuring you always start with it and the [Unique] tag, so you don’t gain too many Ballistas.
Repose
Skill
Show Effects
Veronica’s strongest support card and an incredibly potent Draw Engine for any deck. It costs 1 AP, shields and Draws two cards from your other two Combatant card pools on use. The fact that this card doesn’t draw Veronica’s cards gives it an element of pseudo-searching, allowing you to more easily assemble combos involving other characters’ cards.
Pendant of Resolution
Upgrade
Show Effects
An upgrade card that costs 1 AP to use and is the primary way Veronica generates Reload. After use, it causes all other characters' skill cards to generate a Reload stack for Veronica. This card is the only real place Veronica has to consistently gain Reload, making it a valuable addition if you intend her to deal meaningful damage.
Sir Kowalski
Skill
Show Effects
Another draw card for Veronica, this time only drawing 1 at a baseline, but also allowing you to choose one Ballista in hand to grant a Flat +100% DMG boost to. A solid hybrid of cycling and damage, but a card that only really shines after Epiphanies are included.
Note: Sir Kowalski’s multiplier is additive with Ballista’s damage and not multiplicative like Reload’s, so it is just whatever it was +100% added on top.
Bombardment Prep
Upgrade
Show Effects
Yet another upgrade, this time increasing the Reload max stack size from 3 to 4 while also granting 2 stacks on use. Raises Veronica’s max damage Potential, but it isn’t a must-have card like some of her others unless you know you’ll have the AP to spare in activating it. Additionally, it has the [Unique] tag restricting excessive Reload cap raising.
Note: A baseline Ballista goes from 375% -> 450% with 3 stacks vs 4.

Gear
The Memory Fragments & Equipment suggestions below are based on calculations we did. If you want to check the damage formula and how scaling the damage works in CZN, check this guide.
2/2/2 is the safe pick when playing Veronica in Save Data based game modes thanks to its flexibility which allows you to pick-up most of the damage 4/2 provides while still having access to another 2P bonus which can be used to bring supportive benefits as well. 2/2/2 usually loses out to 4/2 in chaos based game modes or teams where Veronica has limited access to card damage increases howeeer in teams with high amounts of Morale or other forms of Card Damage boosts it can actually edge out 4/2 even in damage assuming high enough numbers.
For more damage use 2P Cursed Corpse (if you can keep Agony on targets at all times). Alternatively for stronger Chaos starts try 2P Seth's Scarab, or if you want more survivability and to double down on Veronica's ability to support use 2P Healer's Journey or 2P Tetra's Authority. If none of that appeals, you can use any 2 strong sub/main stat pieces instead of a final 2P set bonus as well.
4/2 is a pure damage option for Veronica which is stronger for her own personal output in Chaos based game modes and in teams which don't offer her a lot of card damage boosts. However it's damage isn't so far ahead of 2/2/2 that it's a complete game changer so it's only recommended to use this set-up if you already have a strong set farmed. Also worth considering is the fact that in save based game modes Veronica usually isn't brought for her damage so the utility 2/2/2 can provide may be even more valuable to you.
In a lot of cases, flat sub-stats are better than percentage ones when it comes to HP, ATK and DEF. The reason behind this is that in CZN the characters stats are pretty low and you get more value from flat bonus rather than percentage one based on calcs.
Extra ATK DMG% > CRIT Rate% = CRIT DMG% > ATK > ATK%
To fully activate all of Veronica's Potentials and max out the damage she can gain toward her Ballistas and to a lesser extent, Basic Attack Rapid Fire, you'll want 701 ATK initially, but ideally aim for 1000 ATK endgame in her character screen before entering combat. This isn't a mandatory stat goal as Veronica's main role in Save Data modes is usually as a draw-based support, but if you want her to perform at her best in Chaos, it is recommended. However, this shouldn't come at the cost of picking optimal main stats on memory fragments.
Our best Partner recommendation try to balance both the raw damage boost they provide based on our calculations with the additional utility provided by the skill - combined with how it interacts with the character's kit. We have rated each Partner based on how much additional damage and the utility they provide. Read the comments under each Partner to better understand our reasoning.
No calculations in Chaos Zero Nightmare are completely accurate for all scenarios, including the ones below. What team, decks, epiphanies, gear, equipment, and enemies you're facing all impact them. Because of this, take the results as guidelines and combine them with the explanations to make your decisions. Calculations use endgame save data set-ups, including 5 turns of combat using the whole deck with all Ego skills unless otherwise stated.
Best option in most cases for Veronica's personal and team-based damage before considering 6-star Partners with multiple Ego levels. The reason Rosaria is so strong is not only due to her outstanding Passive Stats, but also the fact that she allows Veronica to gain multiple chances at buffing the team every turn whenever she plays a Skill or Upgrade Cards. The combination of both of these effects, in addition to Rosaria's solid Ego skill make her the go-to option for Veronica outside of very high investment alternatives.
Significantly worse at E0 compared to E4, but still a solid option and worthy alternative to Marianne, offering somewhat comparable damage and the edge of granting team-based buffs. It's fine to use either E0 Rosaria or E0 Marianne, but as you get more copies of Rosaria, it's recommended you switch over to her instead.
Veronica's Signature Partner, who surprisingly isn't her best in slot choice in most cases. At E0, she grants less personal damage than E4 Rosaria due to having a lower Combat Attack boost and no ability to buff the team. The one upside of Marianne is that she can deliver a solid amount of AoE damage with her Ego Skill while also drawing a Skill Card, which can be a nice bonus for Chaos game modes, but in Save Rosaria is the clear winner.
A F2P option that's fine to use if you have nothing else, but falls behind in damage and utility. Additionally has has a less impactful Ego Skill than all the above options. Should be replaced as soon as you're able to.
In the Zero System, it's incredibly easy to access all items acquirable via the shop thanks to the five free refreshes you get each shop node - that's why the recommendations below are limited to them only. ATTENTION! Area-specific items can sometimes be more powerful than shop items, but are far less consistent to get or require running a specific world or giving up certain event options. Use the shop list as a starting point for building up your deck saves.
The equipment recommendations are based on items obtainable in Season 2’s Chaos - Burning Life. If you’re running content outside of Season 2, it’s possible some options may not be available for acquisition, or that other options not obtainable in Burning Life may be better.
We're currently working on updating all builds for Season 3.
