I have tried out all the bosses tonight, i think that cerb, zulrah and kraken should be instanced because these 3 monster got special attacks that hits 60s+ and we end up losing gear food which is expensive to afford at the moment. Kind regards ownage, Thank you
The only hard boss is cerb cause of the 3 minions that stack on you Main kraken boss is easy just pray mage and they hit like 1-3s Zulrah is just learning the pattern of attacks, I can do 4-6 zulrah kills and inventory now I've learnt it
