Anderr's Adaptation Matrix

The caster is able to temporarily replace any one of the base characteristics (INT, DEX, WIS, CHA, CON, not STR, as it is impossible to know how to be stronger) with his INT score. For the duration of the spell, the caster's INT score becomes the original value of the modified characteristic. Please see the below for additional effects from the modification.

WIS-You are able to divine aspects of a target creatures personality, and thus their physical tells and motivations. You gain your proficiency bonus on insight checks when you choose wisdom

DEX-You know kung fu. You use your divination to instantly call upon the monk arts. You are able to attack using your modified DEX and proficiency modifier. Attacks with the caster's weapon that hit deal 1d8 + DEX modifier that has been altered by the spell. This spell can be cast at higher levels. If done, add 1d8 per additional level cast. Your AC temporarily becomes 10 + WIS mod + DEX mod

CHA-You are able to divine a person's blindspots in their logic. Using this edge, you are able to add your proficiency bonus to any deception checks made when you choose CHA

CON-Using your divination, you are able to assess symptoms that ail you, and respond accordingly. When CHA is chosen, you gain advantage on saving throws against poisons.
