Powder Ghast

The Powder Ghast is a mob that spawns randomly in the Dwarven Mines at any time.(This is not part of the regular cycle of events, it is a random occurrence).

Players receive Mithril Powder for every bow shot they land on it and there is no final reward upon defeating it. It is immune to melee damage. When one spawns, the following message will display in chat telling players the named location of its spawn.

Note: Divan's Gateway is not the only place the Powder Ghast appears in; it also appears in Rampart's Quarry, Cliffside Veins and Forge Basin.

Tips

 * The Runaan's Bow is particularly useful when fighting it since each bow shot launches 3 arrows and, thus, triple the powder.
 * Seems to be immune to mage
