I once, got killed by necks while wearing full silver. I could pretty much kill anything in the game, berserkers, clearing out entire fulling camps, events, no problem. Then i was in water cause i jumped in for an item, then 4 necks followed me in the water, knockback, knockback, knockback, knockback, nothing i did could help my poor character against the relentless assault of knockback necks... i died. Being able to do nothing in water is one of the most absurd mechanics they implemented, i mean why.
