Tar Slimes (Growths) have the following:
-Far ranged attack
-Puts tar debuff on you that is legendary-bad especially during these stamina changes
-Poison damage as well
-Also knocks you back

They need to at very least remove one of these mechanics from their attacks. It just feels like they were given every single ability in the game.

Overall a decent monster for the game. I have found dodging the attacks using the dodge roll is extremely important to close the gap between you and them. Poison pots help a bit. Bread is an amazing stamina food. You probably want at least one ally going searching for tar pits.
