The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
You want Int? Play a Half-Giant and apply the Primordial Giant template from Secrets of Xen'drik pg 79. +1 LA for +4 Int essentially. If you use the half-giant racial class from Complete Psi 148 and don't take anything past the second level (nothing in the book says you have to, but talk to your DM) you can make it LA 0. From there you can apply the Phrenic template to gain another +2 Int because a lesser half-giant is not naturally psionic, so +2 LA for +6 Int so far.
