Modify Spell Cooldown

Description

Modifies the cooldown of a learned spell on the target player. The result is always clamped to >= 0.

Three modes are supported via the mode attribute:

Mode (mode=) Behavior
SET (default) Replaces the current remaining cooldown with the configured value.
ADD Adds the configured value to the current remaining cooldown. Negative values reduce.
MULTIPLY Scales the current remaining cooldown by the configured factor. <1.0 reduces, >1.0 increases.

The cooldown attribute is parsed as a PlaceholderDouble, so it supports placeholders and math expressions.

Use this for one-shot events — cooldown resets on kill, procs that bump a single cooldown, boss abilities that double a player's cooldowns, etc. For stackable passive cooldown reduction, this is the wrong tool: chained MULTIPLY calls compound (0.8 × 0.4 = 0.32, not the additive 1 - 0.8 = 0.2 players expect), and the order in which different sources apply is non-deterministic. The right pattern is to define a COOLDOWN_REDUCTION stat, let CDR sources stack additively into it, and reference it from the spell's Cooldown: math expression.

Examples

Reset Fireball's cooldown when an enemy is killed:

Skills:
- modifySpellCooldown{spell=Fireball;cooldown=0} @self ~onKill

Apply a 5-second cooldown bump on the spell that was just cast (negative ADD reduces):

Skills:
- modifySpellCooldown{spell=Fireball;mode=ADD;cooldown=5} @self

Halve all cooldowns on a one-shot proc:

Skills:
- modifySpellCooldown{spell=Fireball;mode=MULTIPLY;cooldown=0.5} @self
- modifySpellCooldown{spell=IceLance;mode=MULTIPLY;cooldown=0.5} @self

Drive cooldown reduction from a stat (one-shot recompute):

Skills:
- modifySpellCooldown{spell=Fireball;mode=MULTIPLY;cooldown=1-<caster.stat.COOLDOWN_REDUCTION>} @self
