each tower lvl has a superunique mob(maybe her sisters or something) that has x chances to open portal to next one

tower lvl 1 90% chance to open portal to next lvl
tower lvl 2 75% chance to open portal to next lvl
tower lvl 3 60% chance to open portal to next lvl
tower lvl 4 40% chance to open portal to next lvl

Countess is a bossmonster and frequently drops runes from hel to ist(atleast in hell)
plus maybe some unique item unique to her

Each temple (exept the one with tome) contains a superunique boss-ish mob(druid skin) that has 25% each to drop a

plus maybe some unique item unique to him
