PRISMATIC PRISON OF PRIDE TRINKET
The possession of this trinket (or immerseus one) makes the choice between int and crit much more clear.
It essentially increases scaling of crit by 9%, while leaving int untouched. this does not affect mana tea, but does affect overall throughput. If you have this trinket, gem crit! int socket bonuses are still probably worth it. Either way, this trinket is the game changer when it comes to gearing.
