Ulv do 80 damage but have 40 hp , are a weak version of fenlings but have the same damage , attack faster and in groups
Cultist are a pyro fenrling so go with root armor its a suicide
I think with full iron/wolf its a good choise , no lights armors
And if you have a iron sledge use it , its the best weapon to use there ( i have blunt skill at 95 , i one shot ulvs but cultist take 3 hits to die with the sledge )
Bats are pretty a fill mob there , literally do 1 of damage but in some holes are 5 on you and are hard to hit ( not attack like mosquito ) , iron sledge do the job
