Assault rifle, throwing, sneak and TM
You may just as well roll another char because you beat the game already.
As for the build, it's excellent and I only have very minor nitpicks that won't matter much, but can make your life easier:
- temporal manipulation doesn't need to be this high
- you need ammo, good way to get ammo is pickpocketing (~60-80 effective)
- your damage is monstrous, you don't really need 18 perception
- why no put 3 of those Per stat points into Dex and take Grenadier? It, combined with Temporal Increment from your psi pool, will make you almost able to spam damage dealing grenades
- to spam grenades, you need grenades, why not increase chemistry to make them?
- biology that high is not needed, SSD won't affect you 99.9% of the time and your build is strong enough to tackle hard and even DOMINATING (don't play DOMINATING as a first run)
