Second Draft
Thanks for all the advice. I can only use PHB and ExPsiHB, so I can't use ideas from other sources. Turns out I have 300gp in starting equipment, so I can get some banded mail and drop my Dex to 12.
Here is my second draft. 28-pt DMG standard point buy system.
Str 16
Dex 12
Con 14 +2 racial = 16
Int 8
Wis 15
Cha 8 -2 racial = 6
Feats: Psicrystal Affinity (Resolve), Psionic Weapon, Psionic Body
Powers: Biofeedback, Thicken Skin
Major Equipment: Banded Mail, Dwarven Waraxe, Heavy Wood Shield, Handaxe, Sling
PP 3
AC 19
HP 25
Fort +6, Ref +2, Will +4
Concentration (5 ranks) +8
I admit expansion and biofeedback look good. But at 2nd level they both last two minutes, which probably means one fight, which probably means I'm out of power points after using them both. Also, I don't think I can sit around for two rounds powering up while the rest of the party fights the baddie. I'm the tough. So I took only one of the one minute/level powers, and it was biofeedback because it avoids damage while expansion attracts it. And as I said before the party is healing light.
And if I really want to be expanded, perhaps the party wizard can hook me up.
I thought about expansion with Dex 14 because then my AC drops only by 1 when I expand. But I decided more power points at fourth level would be good.
I'm not really happy with Thicken Skin. It seems like a long term purchase. Right now it is +1 AC for 20 minutes. I like the 20 minutes part, but the +1 AC isn't all that inspiring. Any other ideas for a longer term power.
