Sacred reservoir + abyss

Hi, i found myself in a situation where there is a rare monster and abyss rift into the boss area, the only problem is that you have to walk up to the boss to trigger him and cant attack at all, i feel like it shouldnt be possible.

Map: Sacred reservoir
Boss: Zahmir, the Blade sovereign
Extra content: ritual altar

You can't attack anything, just slow walk to boss and start encounter with all at once. Was fun!
