So I took my main Dahlgren (died over a hundred times, skills are low) to my "arena" world.

I've built there a small roman style arena to not only let enemy mobs fight against each other in a controlled setting, but also so I can try myself at them.

Well, here's my equipment:
Full lvl 3 padded armor (head, chest, legs), lvl 4 linen cape (for those four additional armor!), lvl 2 Black Metal tower shield.

Food was:
Lox pie, wolf skewer, blood pudding, almost 190 health.

I spawned a ONE star fuling berserker.

Boy, did it not end well.

"Me smash!"

Yes, he did smash. Me. First hit I could kinda block. The next hit took a massive chunk out of my health, the third hit sent me to my instant death.

I don't even want to know how I would fare against a TWO star fuling berserker.

Edit: I raised my blocking skill to 50 and tried again. Still no chance. Same result.

Only with Bonemass activated was I able to defeat him.
