[ZG][SPELL][SHAMAN] zandalarian hero charm wrong trigger if used with Chain* spells

[Markus909]

Current Behaviour

Using this item with a chain lighthing/heals (shaman) it reduces its spell power for every target damaged by the spell (-17, -17, -17, ...).. If the chain-lighting proc the talent Lightning Ovearload, it also procs double spell power reduction on trinket's bonus .

Expected Blizzlike Behaviour

Use: Increases your spell power by 204 for 20 sec. Every time you cast a spell, the bonus is reduced by 17 spell power. (2 minutes cooldown)

The bonus spell power should be reduced only on cast, even an istant cast, but only on casted spells.

Source

tolltip of trinket -> https://wotlk.evowow.com/?item=19950

Steps to reproduce the problem

1. equip the trinket
2. use it to empower your spell power
3. cast a chain-lightning on multi target.
4. check the buff counter

Extra Notes

it also remove a stack if the shaman is using Lightning Shield, and be hitted by an enemy.

@Markus909 I don't understand the report. -17 is for every target or maybe is multiplicative (-17,-34,-51, etc). If the 1st case, so this is completely blizzlike.

[Markus909]

@UltraNix the buff counter lower for every target, instead of every spells. So, if i cast chain-lightining and i hit 3 target i get -17*3= -51 spell power bonus.

Okay.
