It puts these on the ground:

Lava Slime Boss Projectile

Leaps at a target up to twenty tiles away and slams down in a five by three tile box, knocking players back, smashing every wall within three and a half tiles while it is in the air, and covering the ground where it lands in slime.

Hops around near where it spawned when nobody is in range, waiting ten seconds between hops and never straying more than twenty five tiles from its spawn point.

Winds up for one second, then sprays fireballs in a forty degree cone, one every fifth of a second.

It puts these on the ground:

Fireball Projectile

Every fourth volley it throws lava blobs in a full circle ten tiles out with no warning, and they curve back toward it and heal any other monster they touch for a fifth of that monster's health.

It puts these on the ground:

Lava Slime Boss Projectile

When enraged its wind-up, flight and recovery all get shorter and its fireballs come out faster.
