The Opener of Kimon

This is one of the hardest rare monsters to find because it keeps teleporting to different locations on the map, however, it will always be in an area occupied by the Onis.

Below you can find a map that displays a highlighted area in which you may find The Opener of Kimon. If you’re having trouble finding him, he might be on a respawn cooldown.

If you see him, you should attack him as fast as you can before he opens a portal and disappears from the area.

As for this creature itself, it has a psychic shield and a demonic shield. He has quite a lot of ground attacks and tricks up its sleeve. His most dangerous attack is the standard Oni attack where he disappears and creates a circle on the ground that throws you into the air if you’re caught in it. Be sure to avoid that one.

He will sometimes drop an [AE Overcharger] which is a very powerful gadget. It will convert 15% of your damage into additional AEGIS damage for 10 seconds. That is very useful in the Tokyo dungeons.
