I'm thinking I'm just going to make a epic power that will allow me to add a bigass bonus to my int. Also, how would acorn of far travel help me?
This way lies madness. For zero XP, and no other spellcasters contributing spells, you can get:
(All Permanent)
+23 Armor bonus
+23 Natural Armor bonus
+3 Armor bonus of deflection, divine, insight, sacred, vile, ect.
+14 enhancement to every stat, each saving throw (so stacks with resistance), spell resistance, and natural armor.
Also a +4 inherent bonus to each of those things.
Energy Resistance 14 to everything.
DR 7/Epic
Ward 20 points (negates first 20 points of damage from bludgeoning/Piercing/slashing damage each round)
Ward 35 points against each energy type (checked before ER, so effectively ER 49, but the first 35 work even against Searing spell ect.)
Immunity to any and every spell ever, provided you have the time to sit down and think about it long enough to name every single spell you want to be immune to. (Can be overcome with a Dispel directed at your ward, sort of, because they are separate wards, they would have to target each one and somehow discern which ward is protecting against which spell.)
And all that will cost you 0XP, and 0gp.
