I’ve noticed RuneX has an auto loot bag. I would imagine the SpawnPK version would have auto loot and a DR bonus. I would be more inclined to risk more if I could receive a BM bonus and/or DR bonus.
Spitballing at this point, but what about a bonus for not having an alien in addition to a yoshi? I would be much more likely to have fun risking all my loot rather than an instant tele to the bank all of the time.
I wouldn’t even care if the bag was a 5% chance in the enchantment chest, it would be another mode of play.
