The Slime Boss is one of the three bosses that appear in the first act Exordium.
Pattern Will always go through the pattern of Goop Spray, Preparing, Slam and then repeats. Slam hits for quite a bit of damage, so try and force him to split by his 3rd turn by dealing 70+ total damage, or use Weak and/or a lot of Block. Note: Splitting this boss will cause his intended action to interrupt so bursting him down when he is close to splitting (70-80 HP) can aid in defeating the residue slimes after splitting.
Split occurs when its HP is at 50% or below.
