In video the ele using sp potion MATK 8K.
8000*1.5(Quick Cast)*2(attribute)=24K
How can they making extremely damage
I hear something about a ice proprity necklace ? like agni maybe XD ?
Not sure if it really exist rumor or whatever but well
Also there a taoist in this party maybe it was is zalcai/storm caller combo
your VDO was private 
Its possible to hit that damage with chapparition and melstis combo… I myself hit 19k Matk at full stack and dealt like 60-70k per tick on Blut I think.
double stacking will be gone s00ntm
DT is 2k power + - can;'t remember the numbers 3k magic + 80% chap will do the magic
FC needs 7.4k (-80% chap = 4k magic i have 3k magic myself with only corona.)
