As per the rules in the Players Handbook II from D&D 3.5 I am going to allow characters to retrain. This means that everytime you change a level, if you wish, you can change one aspect of your character.

Here are the things you can change (but remember only one change per level):

Class feature: Exchange one class feature option for another. For instance: a cleric might change domains, or a ranger might change animal companions, combat style or favored enemy, or a sorcerer might change familiars or a rogue might change a special ability.

Feat Exchange : swap out one feat for another for which you qualify.

Language Exchange: swap out one language for another (I will require an in-game explanation for this).

Skill Trade:  swap up to four ranks between two skills. Though the skill where the points are being added must be a class skill, the points taken can be from a class skill or cross-class skill.

Spell Exchange:  swaup up to two spells known for others. This is basically only applicable to sorcerers and bards.

Substitution level Trade:  swap a class level for a substitution level. Substitution levels are found in different D&D 3.5 source books and are not part of Pathfinder so if you don’t know what they are don’t worry about them. I’ll post about these later.

 

I will require some in-game explanation for these changes if the changes are conspicuous. This is a good way of adjusting your character however as you get a better idea of how you want to play them as things progress. This is particularly the case in regard to feats and skills.
