I was just curious what fortitude saves epic mobs have and if stunning blow works well on them? I'm talking about stunning blow from a 32 point and moderately easy to get gear, not a theoretical maximum with completionist, fighter past lives, perfect gear, pefect buffs, and mob debuffs.

I was thinking about making a 32pt WF 20 fighter kensai specalized in warhammers.

Passive stunning dual wielding 5% weighted warhammers and 10% fighter alacrity capstone

Stunning blow, fortitude DC 40
10 base
4 fighter enh
3 WF enh
10 from weighted weapon
13 from str (assuming 36 str - 18 base + 5 levelup + 6 item + 3 fighter enh + 2 rage + 2 exceptional)

So my question is this. Is a DC 40 stunning blow attack good enough to stun epic mobs? If not, what DC, gear, buffs, debuffs are needed to make stunning blow effective?

Thanks.
