There's no current limit to the number of Dark Eyes you can summon. I recommend capping it at about 10 like Papilions, as numbers approaching 20 or higher start to drastically halt the server.

That's weird, it shouldn't actually affect server performance regardless of how many mobs are in a battle. I could see it maybe happening at a few key points, maybe when the round shifts, but other than that it shouldn't be affected.

This exact sort of thing happened whenever Papilions could have infinite butterflies.

When ALL the monsters get a turn that isn't total controlled it heavily hangs on the server, similar to how the papilion butterflies worked.

[Trexmaster]

The server noticeably chugged whenever the eyes were going through their turns, when the turns were being held on either player's turn, the lag was non-existent.

[Neus]

This was corrected in the latest update, the game should also chug less when there are lots of enemies in a battle.
