Divine Divinity [1.0.7.1] - Diviner Set Spellbinder, no greens, 170 viable

quick question. How hard was it to obtain the set items?
Might be a noob question, but this build looks pretty impressive, so i would like to get my character close to it.

My first character tho, so im playing currently the Callidor’s tempest beginner build.
Would you say its easy to transition into your build at lvl 100? with some farming for legendarys of course.
