World-Tree Tail (Japanese: 世界樹の栗鼠の尻尾 World tree squirrel's tail) is a weapon skill in the beast category which debuted in Fire Emblem Heroes; it is a personal weapon of Ratatoskr. World-Tree Tail allows its user to move after certain actions; and when its user's HP is not low, it boosts their stats, boosts their attack and speed based on the number of nearby allies with low HP, boosts their special cooldown charge, and reduces the damage of the foe's first attack.

Enables【Canto (2)】.

Accelerates Special trigger (cooldown count-1).
At start of combat, if unit's HP ≥ 25%, grants
Atk/Spd/Def/Res+5 to unit, grants Atk/Spd+X
to unit (X = 9, - 3 × number of allies with
HP ≤ 40%; min 0), grants Special cooldown
charge +1 to unit per attack (only highest
value applied; does not stack), and 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 turn, if unit is adjacent to only beast
or dragon allies or is not adjacent to any ally,
unit transforms (otherwise, unit reverts). If unit
transforms, grants Atk+2 to unit, inflicts
Atk/Def-Y on foe during combat (Y = number
of spaces from start position to end position
of whoever initiated combat, + 3; max 6),
and also, if Y ≥ 5, reduces damage from
foe's first attack by 30% during combat.

【Canto (2)】
After an attack, Assist skill, or structure
destruction, unit can move 2 space(s).

(Unit moves according to movement type. Once
per turn. Cannot attack or assist. Only highest
value applied. Does not stack. After moving,
if a skill that grants another action would be
triggered (like with Galeforce), Canto will
trigger after the granted action. Unit's base
movement has no effect on movement granted.
Cannot warp (using skills like Wings of Mercy)
a distance greater than unit would be able to
move with normal Canto movement.)
