Teleporting water sphere barrages behind dungeon masonry
The Dark Caster is a robed skeletal mage that stalks the stone halls of the Dungeon. Upon spotting a player, he stands stationary and casts volleys of slow-moving Water Spheres that pass freely through walls and bounce off solid surfaces. When struck or after finishing a spell sequence, he teleports to a different nearby open tile. With only 2 base defense and low durability, he crumples quickly once engaged, but his bouncing magical orbs can flood narrow corridors.
Clearing magical artillery to loot dungeon keys
Swinging a melee weapon or firing arrows directly through incoming water spheres will neutralize the projectiles before they hit, making fast weapons ideal for closing the gap. Defeating Dark Casters yields reliable stacks of Bones (97.1%) and offers a 1.52% chance for a Golden Key to unlock locked Dungeon chests. Dedicated treasure hunters may also uncover the rare Clothier Voodoo Doll (0.33%) or the Ancient Necro Helmet (0.22%).
Trivia
- Unlike the Water Bolt spell available to players, the Dark Caster's Water Spheres do not emit dynamic light.
- Striking the Water Sphere projectiles with any weapon instantly destroys them without dealing damage to the player.
