RETRAIN

Through an apprenticeship or period of self-instruction, you dedicate intense focus to mastering a new skill set - at the cost of others you previously mastered. The extent to which you can acquire new abilities in this matter is relatively limited; those who wish to make more extensive changes often invest in a mnemonic editor instead.

Activity: You spend the day focused on a particular skill in which you don't have the maximum number of ranks. At the end of the day, attempt a skill check with that skill DC = 10 + 1 and 1/2 your level. You can't take 10 or 20 on this check.

Results: On a success, you gain a rank in the chosen skill, and you lose one skill rank in a random skill with the same ability modifier, if you don't have ranks in a skill with the same ability modifier, you lose a rank from a random skill instead. If this causes you to no longer meet the requirements for a feat, piece of equipment, or the like, you lose access to that option (and gain any associated penalties) until you again meet its requirements.

Multi-day: If you spend a full week retraining, you can instead learn a new feat that requires no prerequisites, in which case you lose a feat of your choice.
