Bosses with kill counters in online games. Nioh 3 has a thing where the spirits of dead players coalesce into a tough as nails boss that spawns randomly in the open world and drops really good loot if you manage to kill it. That's already neat but something I got a kick out of was that it displays how many players it kills until someone eventually takes it down. I managed to take one down earlier with a player kill count of over 61,000. Is it completely cosmetic? Yeah. Did it feel cool as hell to be the one who ended his reign of terror? Hell yeah.
