Slekeleon
From Dungeon Defenders 2 Wiki
Not to be confused with Plaguing Hulk
The Slekeleon is a mini-boss frequently found in the Chaos trials and Incursions maps. It is first encountered in the Temple of the Necrotic map.
Description
The Slekeleon resembles a giant Skeleton Orc. His behaviour is similar to the Plaguing Hulk; slow attack and move speed, but heavy melee swings and large melee range. Unlike the Plaguing Hulk however, the Slekeleon respawns every wave at the spot which it previously died.
Strategy
The strategy is generally the same as with the Plaguing Hulk, stay behind him when attacking, and prepare to back up whenever he is about to swing.
Due to respawning at his death location each time, you can prepare by setting extra defences or gather up your team to quickly focus him down.
