Critical for Ranger

[IpedzI]

So, i want to raise my critical rate but don't know how.
Gems are one way ,but it is a no no .
Adding agility points is one option too but slow , and i was planning to go full str.
Here are my stats, so how can i raise my critical rate ?

apart from gems...for now u can lvl up ur simplicity and cruelty soul nodes. complete ur savage set....also add some points to agi from soul....and u can use the silent destroyer for the additional 8% crit rate
