Draw a Stickman: EPIC 2

This is the 2nd boss you'll come across in the Drawn Below mode. The boss fight is simple enough. Just have to free the 3 smaller creatures with your sword and use rain on them to make them grow and jump on the boss. Should only have to dodge one attack from the boss at most while doing this. Problem was after doing it a few times the achievement never unlocked for me. So finally had the thought that you can't take damage in the entire room leading up to the boss which is a little annoying to get through the swamps without taking a hit but you can just die and restart the room until you do. Once I did the entire room without taking damage it finally popped.
