Spawns only I time and does not respawn or has not respawned for me and drops white req arrow, chara knife and sun. He also used to drop Dark Helmet, and Pumpkin (Halloween Event 2020). (i am an old player and i can confirm that he dropped dark helmet. )You need to click "HalfYumy" Npc to go to the arena
Every time you restart your private server dio respawns which means you can get 1.4 million money every 30+ seconds with a good stand and luck
Does not give dark helmet now and does respawn every 10 minutes or so.
And when he respawns he is dead on the ground and u can only kill him with reaper for now
