Infernalist with Blink & Temporalis, ideas to increase critical hit chance?

Hi,

At the moment, critical hit chance during combat is 79.1%. It's doing OK as bosses disappear in seconds. T15/T16 mapping can be achieved in around 2 minutes.

Aside from gear, any node in the tree that may help?

Current level is 89.

Tempted to replace both rings with these but then fire/cold/lightning resistance will suffer:

Build is here:

Thanks!

Passives:
Sudden Escalation (31 Increased Critical Chance for Spells) - only 3 points away.

Warning the following is expensive
Jewels (MAGIC and CORRUPTED):
15% Increase Critical Chance
Another Useful Stat Here! (Crit damage? Elemental Damage?)

to go with:
The Adorned Diamond (0-100% increase effect of corrupted magic jewels)
89% cost around 350 divs
94% cost around 450 divs
100% will cost an arm/leg and your firstborn.
