Forum:Adamantite gear bugged?

I got my first full set of Adamantite armor melee 46 defence, so i thought hey im cool funny thing that I was mining adamantite some more here comes the big bat and attacks me. As if im wearing cobalt armor i find the whole thing strange.

Is it a bug or is it working as attended? I do expect mini-boss's and boss's to do good damage but not hard normal mobs.

Thoughts?
