The Fungal Heart

Boss

A boss (combat level 42), found in Fungus Domain, Fungus Cave. It has 5,200 health, 38 armor and 28 magic resist, and hits for 44.

Each kill gives 5,500 Mastery XP to the mastery of the weapon you are holding. Everyone who damages it gets the full XP and their own loot roll; party members standing nearby get the XP too. On a Slayer task it also pays Slayer XP — see below.

It respawns 1m 30s after it dies.
