What are dropchances? Do they depend on damage done?  Are damage counts Set to each server or to whole EU/na realms?

It's RNG

Damage plays a apart, have to be in top 20 or top 80 for damage. Although its still RNG

For increased drop chance you do. But u can still get a zarka for just hitting boss once if ur lucky. I know cus b my guildy died 4 times in the fight and still got it... Extra salty.

I fought the boss 6 times first 5 all I got was a hunter's seal.  this last time I fought I died twice and some how got a staff.  so as for that RNG felt pitty on me to give it.

i have a lvl 5 node, 5 luck, blessing and S kzarka and all i ever get is massive server lag and 1 hunter seal

Does the node level some how work on the bosses loot table?

Thought that was independent so modifiers didn't work like trash loot.

The guide i watched theorised that node level, damage dealt and knowledge of Kzarka (from amity game near by) all played their part in drops.

In this case i really do hope it is RNG or the guys in front with Kzarka weapons already will be first in line for the drops. I've already seen evidence of one player having more than one Karka weapon box.

it's not a secret that players with highest damage have a better chance to get to the top loot table and have better change for a weapon BUT it doesn't change the fact that one of the first weapon boxes I saw dropping went to a total noob not knowing much about the class and proper skill rotation etc so probably didn't pull off any huge numbers ( I'm not trying to offend the guy, just saying). So yeah.. RNG 

if that's the case of weapon damage being a key factor on xbox BDO then zerkers have had a massive advantage from the start which is BS and shouldn't be allowed so they should drop the damage rate being a higher drop and really make it RNG

Node level doesn't effect world boss loot table.

It's still rng but the top 20, 50, and 70 have better chances then everyone else.
