This may already be implemented and I'm forgetting. If so, my bad.
But you know how we have clickies in the game that give us a collectable like a Necklace of Prayer Beads or this or that when we find the occasional Adventurers Pack in the gloomy back of a dungeon?
It would be way cooler to find actual loot on those. I mean, it makes more sense to me. Did the guy get killed by an Ooze only to drop one stinking mushroom or did he maybe have like a +2 Keen Dagger of Acid in that pack? Maybe a spare Ring of Protection +3, a few Haste Pots...something!
