Memory Blur mechanic for SPA 62
Chance formula is effect chance + charisma modifer + caster level modifier
Effect chance is base value of spell
Charisma modifier is CHA/10 = %, with MAX of 15% (thus 150 cha gives you max bonus)
Caster level modifier. +100% if caster < level 17 which scales down to 25% at > 53. **
(Yes the above gets worse as you level. Behavior was confirmed on live.)
Memory blur is applied to mez on initial cast using same formula. However, recasting on a target that
is already mezed will not give a chance to memory blur. The blur is not checked on buff ticks.
SPA 242 SE_IncreaseChanceMemwipe modifies the final chance after all bonuses are applied.
This is also applied to memory blur from mez spells.
