Retraining: Every time you gain a level, you can retrain your character: change one feat, talent, or skill selection you made previously. You can make only one change at each level. To be eligible for retraining, the ability in question should not have played a significant role unless there is a good reason for the change. Obvious: You can’t violate any normal requirements, prerequisites, or ability sources when retraining.
Changes: Replace ‘Block’ and ‘Deflect’ with ‘Block and Deflect’.
