At lvl 17, I can Empower a Split Psionic Ray on Disintegrate with a 4 surge, that's 50d6 (+50%) + 50d6 (+50%).
.
Currently I'm at level 9, but this is my planned build and so far it's working awesome. -IF- I ever roll a 4 on my chaotic surge, it's lights out for anything. Empowered Mind Thrust on a 4 surge is currently 14d10 (+50%)dmg with a 25 Will Save DC, Empowered Energy Missile on a 4 surge is currently 13d6 (+50%)dmg on up to 5 targets with a 25 Reflex/Fort Save DC.
.
Solicit Psicrystal lets my Psicrystal take over the Concentration on Telekinetic Maneuver (Bull Rush, Trip, Disarm, Grapple/Pin) or on Energy Current so I can continue nuking. Both are excellent for offense/defense and crowd control.
Vigor/Share Pain + Inertial Armor (Share w/ Psicrystal) = lots of defense, especially if I Wild Surge them.
Remote Viewing + Retrieve = Inter-dimensional Carmen San Diego
Incarnate can make all kinds of psionic powers and effects permanent, both in the world and present on myself.
Metamorphosis = ultimate utility, and fly for 1 min/lvl. In battle, Metamorphosis with 4pp augment, Reduce size -2, +4 Dex for a +4 initiative, +4 reflex, +6 AC, +8 Stealth (Tiny size bonus) and Fly.
.
At lvl 20 with a +3 Surge Crystal on a 4 surge: Maximized Empowered Mind Thrust is 33d10 (+50%), Max Emp Energy Missile is 32d6+32 (+50%) to 5 targets, Max Split Psi Ray Disintegration is 64d6 + 64d6, Max Emp Energy Wave is same numbers as Energy Missile, except in a 120 ft cone. Max Emp 4 Concussive Onslaught would be 16d6, so static 144 force dmg per round in 60ft diameter aoe for 20 rounds, Fort save for half
Disintegration = static 384 dmg with a Fort save of 26 + whatever your Cha Mod is, twice. So potential 768 damage if they fail both saves.
Mind Thrust = static 495 dmg with a Will Save of 27 + Cha Mod.
Energy Missile/Wave/Current = static 336 cold/fire dmg to 5 Targets/Cone with a Fort/Refl Save of 26 + Cha Mod.
Share Pain+Vigor would give me and Psicrystal 190 health, Inertial Armor would be +22 AC, etc.
.
Max dmg across 20 rounds would be 2880 on concussive onslaught in a 30ft radius (60ft diameter) area. Max dmg across 20 rounds would be 6720 for energy current, with a possible 6720 more because it can arc to a second target within 15 ft.
.
I can manifest Concussive Onslaught, and it bombards an area for 20 rounds, then I can manifest Energy Current and swift it to my Psicrystal and it can maintain the concentration for me, and then I can nuke with Split Psi Rays.
.
I'm still looking for other items and effects that can boost my ML, so I'm going to get a couple Invigoration Setting Stones for my Psicrystal Staff (+1ML & +2DC for 10 mins each), and a +1ML Ioun Stone. Any ideas for other items?
