Steps to Reproduce

This happens surprisingly easily and can be consistently reproduced.

1. Find a Bronze Dungeon boss room.
2. Build a whole bunch of walls out of something that really shouldn't stop the Slider, like Holystone.
3. Hit the Slider to start the fight, then hide behind walls to keep the Slider's center out of sight.

What You Expect To Happen

I expected the Slider to persistently destroy everything so long as there were players inside the arena, no matter how well they tried to hide.

What Actually Happened

The Slider gave up and lost aggro after breaking three or four layers of wall.
