I talked to Yendor, we called this game a draw :)
As I know a little bit about coding , my assumptions are :
1. Either Goblet is bugged to be available to pickup for enemies, like enemies can pickup mushrooms or Wand of Fire summoned creature has this flaw to be able to pickup Goblet. Then something killed that enemy/summoned creature leaving blood path.
2. Burst of Flame effect (exploding fire?) somehow messed up with Goblet Shield effect of breaking especially under flame cloud.
