pub fn crit_chance_scaled_effect_index(description: &str) -> Option<u8>Expand description
Reads the effect index whose value is a percentage of the caster’s own critical strike chance.
The shape is "... critical strike damage ... $sN% of your critical strike chance".
The effect the percentage lands on is not named by the description; it is the spell’s own
crit-damage effect, which ships with a base value of zero precisely because the client
computes the real one from this statement.
Only $sN qualifies: a cross-spell $<id>sN states another spell’s value, and $mN/$oN
are not the base value the game scales.
None means the description makes no such statement.
