See the attached file for the doubly resisted damage - two instances of resisted electrical. The save this was done on has Tricky Trajectory with 5 spec points into it, no Heavy Metal. Was wearing blast cloth and orobably has something to do with it.
About the damage - it seems to scale unreasonably high with INT through High-Technicalities. Using Hypercerebrix to go from 7 to 9 INT is enough to boost damage from typical damage 1500 to 2000, with Tricky Trajectory bur without Heavy Metal. Sure you can blame it on high/low rolls, but dealing 2000 non-crit damage shouldn't be possible at all from my math, regardless of how the various bonuses apply, I can never arrive at 2000. I've seen others deal over 3000 on a non-crit with heavy metal, too.
