That’s just a link to the skill simulator, you didn’t link to your build.
I’m honeslty not sure how I feel about getting SPR for zalciai alone… Usually the builds that focus on SPR have something -more- than just zalciai that scales with SPR (blessing, stone skin).
Think of it this way: If you went DEX / INT, you would get about the same critical rate, with evasion, and without the disadvantage of having to cast zalciai to debuff the enemies but with the drawback of not increasing your party members critical chance as well.
Remember zalciai at lvl 10 has a base bonus of 20 but only scales with 0.8 SPR per point while DEX increases critical at a rate of 1 per point. I believe there’s no difference between lowering your enemy’s critical resistance or increasing your own critical rate when you’re soloing (but of course, lowering enemy’s crit resistance benefits the rest of your party).
