RG Live WotLK 3.3.5a

Meteoritkristall soll laut wowhead kommentaren nicht mehrfach auf einen Zauber pro Tick procen.

Aktuell kann man z.b. beim Lichking als Paladin mit Zorn + Weihe sofort auf die 20 stacks kommen. Was man gut ausnutzen kann.

for wild growth, i wonder if it would stack 6 times at once. i know this would only go to a druid after pretty much every other caster class, but im still curious

It doesn't stack with spells that hit multiple people (CoH, WG.) It does stack with Penance multiple times though. I have tested it with Divine Hymn; it does not stack multiple times, which leads me to believe Penance is a unique spell when stacking this buff and also Solace of the Fallen.

It does stack but only once per cast but for beacon it works double faster
