Vengeance calculation taken where?

[adeyke]

Is my check in the mail?

I haven't done any research into that at this point.

Will I win the lottery?

That's rather unlikely, but it's theoretically possible, if you've bought a ticket.

Does the skills.txt Etype column == "Fire" actually determine the +fire skills property qualification for magefists?

I guess so. I couldn't find any skills that have that listed but which aren't affected. It surprised me that Corpse Explosion and Fire Golem worked with +fireskills.

I see vengence is listed there as "Cold" so my suspicion would be that a (modded) version of something like magefists for cold skills (property) would benefit it, eh?

If such a mod is possible, it's beyond my abilities. I wouldn't know how to change it to +coldskills.
