Perhaps a quick temp fix is like the Seb idol?

On zones it can check for keys. For PoJ its pretty simple, last guy, has loot.

For the multi-god-needs-killed, make them drop keys which can be turned into a PoK quest giver that gives you the final plane key for the next tier.

Should be pretty quick to code and implement.

Hrm, might do that tonight...
