Ectopus

The Ectopus is a miniboss that spawns in the Dungeon with a 5% chance every time a Dungeon Spirit is killed. It is much more powerful than the Dungeon Spirit, but it is very handy for Ectoplasm farming. It has 6000, 70 melee power and 100 ranged power. This miniboss is made dangerous by the fact that it does not allow the player to flee, except with Rod of Discord, Magic Mirror or Recall Potion.

Attack pattern
The Ectopus will float around, firing blue blobs at the player. Like most projectiles, these can be destroyed with one hit. They may inflict the Cursed or Silenced debuffs as well. If the player attempts to escape, however, it will shoot out a blue tendril that reels them in helplessly, similarly to the Tongue debuff. The tendril has no health and cannot be deflected; it has 70 power. During the fight, the Ectopus will occasionally spawn Dungeon Spirits.
