- Spell or Power Retraining
Much like feats, magic spells and psionic powers sometimes look better when you select them than they do after you’ve used them for a while. And when you’re playing a character with a limited number of options (such as a sorcerer or psychic warrior), every spell or power you choose represents a significant percentage of your character’s overall options. You can’t afford to have dead weight taking up valuable spell slots, so ditch that sleep spell now that the party isn’t facing foes with low Hit Dice anymore and replace it with the niftier 1st-level spell you just found in a recent supplement.
Exchange up to two currently known spells or psionic powers for other spells or powers. Each spell or power must be usable by the class and of the same spell level or power level as the spell or power it replaces.
Bards and sorcerers already have a limited ability to learn new spells in the place of older ones. This method of retraining allows exchanges over and above what their classes already permit.
Example A sorcerer could change Lightning Bolt to Fly or Dispel Magic, since all three are 3rd-level sorcerer/wizard spells, but he couldn’t change it to Wall of Ice (a 4th-level spell) or to Cure Serious Wounds (A cleric spell).
Example a 5th-level sorcerer advancing to 6th level could use spell retaining to exchange up to two of his known spell (of any level he knows) for others of the same levels. Then he could exchange one 0-level or 1st-level spell for another just as any sorcerer could upon attaining 6th level.
