Tactics
The Imp Overlord has 2 attacks it can use. The first (and easiest to avoid) is an attack quite similar to the Ancient Wisps attack where flames come from the sky. It is easily noticed and can be dodged by either jumping or using a dodge ability. The second attack is a lunge where the boss swipes at you dealing damage if hit. While not necessarily hard to dodge, the attack moves quite fast and can easily harm you if you're distracted by a crowd of enemies.

The Imp is easily stunned by even the weakest attacks making it an easy boss for fast fire rate characters.

The Imp Overlord can drop the Imp Overlord's Tentacle Imp Overlord
