Might: 9 Range: 2 Accelerates Special trigger (cooldown count-1). If unit initiates combat, unit attacks twice. At start of turn and after unit acts (if Canto triggers, after Canto), inflicts Spd/Def-7, 【Sabotage】, and 【Exposure】 on closest foes and any foes within 2 spaces of those foes through their next actions. If unit initiates combat or is within 2 spaces of an ally, grants bonus to unit's Atk/Spd/Def/Res = number of foes within 3 rows or 3 columns centered on unit × 3, + 5 (max 14), neutralizes foe's bonuses, unit deals +X × 5 damage (excluding area-of-effect Specials), and reduces damage from foe's attacks by X × 3 during combat (excluding area-of-effect Specials; X = number of Bonus effects active on unit, excluding stat bonuses + number of Penalty effects active on foe, excluding stat penalties; max 5). |
|
Cooldown Count = 5 When Special triggers, boosts damage dealt by 200%. At start of turn, grants Special cooldown count-1 to unit. Reduces damage from foe's first attack by 40% during combat ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes). |
|
At start of player phase or enemy phase, if unit is within 2 spaces of an ally, grants "reduces the percentage of foe's non-Special 'reduce damage by X%' skills by 50% during combat (excluding area- of-effect Specials)" and 【Hexblade】 to unit and allies within 2 spaces of unit for 1 turn. If unit initiates combat or is within 2 spaces of an ally, grants Atk/Spd/Def/Res+9 to unit, reduces damage from foe's attacks by 40% (excluding area-of-effect Specials), reduces damage from foe's attacks by an additional 7 (excluding area-of-effect Specials), and neutralizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks during combat. If unit initiates combat against a non-dragon or non-beast infantry foe and unit's Spd ≥ foe's Spd+20, grants "effective against all weapon types" to unit during combat. Otherwise, if unit initiates combat and unit's Spd ≥ foe's Spd+5, grants "effective against all weapon types" to unit during combat. |
|
Inflicts Spd/Def-X on foe (X = total number of 【Bonus】 effects active on unit, excluding stat bonuses, and 【Penalty】 effects active on foe, excluding stat penalties, x 2, + 4; max 12), and neutralizes effects that inflict "Special cooldown charge -X" on unit during combat. While attacking in Aether Raids, if unit ends movement on a space with a Bolt Trap or a Heavy Trap, cancels trap's effect; if unit ends movement on a space with a Hex Trap, reduces trap's trigger condition by 10 HP. |
|
Enables 【Canto (2)】. When Canto triggers, enables unit to use 【Distant Swap】 on ally (this effect is not treated as an Assist skill; if similar effects are active, this effect does not trigger). If unit initiates combat or is within 2 spaces of an ally, grants Atk/Spd+4 to unit and reduces damage from foe's first attack by 7 during combat ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes). If unit initiates combat and foe's attack can trigger foe's Special, inflicts Special cooldown count+1 on foe before foe's first attack during combat (cannot exceed foe's maximum Special cooldown). |

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.
+Spd/-Res
The best IVs for Ninja Shez (F) are +Spd and -Res. Ninja Shez (F)'s base 49 Spd is tied for the fastest in the game (as of the time of her release) and should be maximized in order to allow her to quad attack most of her foes.
Shez's Res stat is a clear dump stat at only base 25 and can be safely taken as a bane as it won't impact any of her matchups.
