The Heroes are ranked based on reliable clears of floor 11 when auto-battling Hunts (some notable manual exceptions may apply).
Tier 1: Heroes with excellent innate strength in their kit (element, skills/utility, modifiers) that allow them to have an edge over anybody who would be considered to be a Tier 2 Hero.
Tier 2: Heroes with average kits (element, skills/utility, modifiers) that can be successfully used to auto the hunt.
Tier 3: Heroes with mediocre kits (element, skill/utility, modifiers) who are viable but may suffer drawbacks when used to auto the hunt compared to anybody who would be considered to be a Tier 2 Hero.
Everything you could possibly want in a healer; low cooldowns on a very strong heal, immunity, and high defense allow her to serve as the maintank.
Extremely high damage places the bunny firmly in Tier 1. Her crit chance bonus and CR gain on passive allow her to keep pace with faster damage dealers and stack her damage to truly eye-popping levels. Do note that she requires good gear and MUST crit to function properly.
Top tier burst damage great for shield busting or even OHKOing. For slower teams, she also has Magic Nail for % HP damage.
After his buff, Crozet is now even tankier than before. He carries a good 75% ATK down debuff with some investment and Mark of Protection will automatically shield and DEF buff him when his health dips low. He is not placed in Budget because he takes quite some work to get from connections.
