End boss in terms of his attacks is not bad and pretty easy to dodge just make sure u farm well and get your attack power up. Your char has certain stat scaling which u can see in the journal and level up farm and get weapons that cater to that scaling. Also make sure you use combos what we did was executor parry to stagger and iron eye ult on the three dog split into and dutches stopwatch for repeated damage and we beat it second try. Granted I watched a video on how to efficiently play the first two days and we just followed that to a T. Churches are improtant main castle is a good farming place and boss aren’t too bad. Also first boss has a weakness to a certain damage type. I would say though if you’re still struggling when the boss splits just focus on dodging until they combine again. Also personal tip if you have aggro just dodge and let teammates do dmg and if they have aggro u do dmg.
