If for example you have 1000 health of out 2000, and you polymorph into a creature with 5000 health, assuming you only get 1000 damage during the 6 rounds what will be your new health after polymorph is over?
Also what will be your health once you polymorph, will it be 5000 out of 5000 full health or calculates the existence damage and takes that into account?
