Best for / not for

Pick her as the Heavy Tactical front. 613,269 HP is second of 12. Venom Burst shreds the enemy front’s ATK by 6% for 4s, so the button works in PvP. Nimble Steps is 27.35% less monster damage on her.

Team

Nimble Steps is personal. One of Toxina, Zara, Conan, or Jack plus real damage is enough monster DR.

Weaknesses

9,347 attack, 11th of 12. Do not gear her as a carry.
No ally buff. Nimble Steps is blank against players.

Best role

PvPGoodGood. HP pool plus enemy ATK shred.
BossFairFair. Injector fires; Steps only if the boss counts as a monster.
ArenaGoodGood. Same as PvP.
CampaignExcellentExcellent. 613,269 HP plus Steps.
SupportSecondarySecondary. The shred is a debuff, not a team chant.

Verdict

Raise Toxina to hold a Heavy Tactical front, not to win the attack column. Star Venom Burst, take Wasteland Wanderer at 31 and 4★ for the 10% stats, and put Warrior damage behind 613,269 HP. Do not raise her to beat Celeste. If you needed a front DEF chant, that is Conan.
