There’s a bug with Gullinbursti’s damage in Teltoc event.
His attack (3 turns after his special skill use) doesn’t apply if there’s any alive mobs/bosses with yellow reflect.
Attack just pospones forever, until all the yellow enemies are dead.
Yeap, I know that Teltoc is going away, but I suppose the same bug will appear in Starfall Circus.
Kindly ask to check.
