What does the evolving shrine do?

"Slain Enemies have a chance to Evolve when defeated"

Is that like normal monsters getting upped to magic, magic to rare, etc. Maybe even rares getting turned into unqiues?

bump

In one map (Vault) i found a fat uniq monster wandering around parts of map i already cleared. He was marked on mini map as a large red dot, moving around.

I honestly dunno where he came from or what was that exackly, my very first encounter with smthng like that.

Maby he evolved?

Bumping this up because I'd like to know too.

I've seen two theories, but nobody seems sure. 1. That the mobs produce EXP and loot equivalent to a higher rarity mob, and 2. That the killed mobs immediately respawn as a higher rarity mob.

The patch notes doesn't really explain it except to say it replaces the xp scarab.

According to this redit post, it' like a combination of what you are saying. They don't respawn but the drops and xp are based off the mob being a higher rarity. White to magic, magic to rare. Not sure how accurate that is.
