Sory for the confusion ... i expressed myself poorly.
I mean mod purely from the autor mind, not that kind of mod that takes existing (often datamined) asets and just adds it to some model or fill missing gasps.
And that +15 isnt somethig that bothers me, since in that combat log its not mentioned ...
But additional 1d10 on crit ... effectively making triple damage, seems ridiculous. :-/
But now, when i read that combat log properly ... how the hells he crited with roll 13 ?
I still dont understand why cant we change Race for our hirelings.

Lets us play Githyanki as racist as they trully are!
