portal gem from act 2 boss

A suggestion.
I know you have a chance to find the skill gem "portal" in the pyramid at the end of act 2.
have not found it myself, but i traded for it.

Also, I know that with the 9.11 patch we should get a proper boss at the top of the pyramid.

My suggestion is that this boss will drop the portal gem is say, 1 out of 10 fights (when slain) plus no drop of this gem anywhere else in the pyramid.

A bit like the special item you could get from hades in the game titan quest. killed him a lot of times on normal difficulty when I was already playing at the end of the cruel (or epic) difficulty - perhaps we will see something similar with poe if you would introcuce this.

other oprions are also possibile.
like 2% drop chance when playing solo, 20% with 2 players, 40% with 3 players and 60% with 4 players. you would force people to play together instead of playing solo.

That skill gem can drop anywhere in the game, just like all other gems. The devs have been against monster-specific drops. I don't think they're going to change that.
