A Exotic spell that takes up one spell slot   

The spell captures the creature and allows the player to begin processing the creature, taking either a trait or one stat point which the creature has the highest stat point on. But if you do it for long enough then it's everything depending on the condition of the creature since if its dead you can't extract much since it can't think of anything.

Also, if the caster is hit before absorption is completed, the caster will spit out the creature and stumble and be stunned for the next round. Will also take extra damage 1d6 from the hit 

At Higher Levels:

Caster can take less damage the higher level they are, 1d4

LVL5: roll with 1d6 to chance absorption of a dead creature, DM will decide what the caster will get based on the roll:

rolled 1- then the dead creature will not be absorbed and instead melt away from the attempt.

rolled 2- caster will absorb one language the creature speaks

rolled 3-absorb 1 weapon skill the creature was proficient in.

rolled 4-absorb all the information for what the creature knew from the last 24 hours

rolled 5 - absorb any life skill proficient the creature is skilled in. 

 rolled 6 - absorb condition infecting skills the creature has
