Yet another crafting help request from a newbie

First off, sorry for the crap pic. I’m on PS5 and can’t have the tier button held down to take an in game screenshot 🙄

Im playing as shaman, basically all spells because that’s what I ended up liking. I recombined this and got T1 cast and fire damage, my build is mostly fire damage, fireball, flame blast, living bomb. Also lightly using CoC with comet, but just recently. I spent a bunch on mana catalysts and catalyzing exaltation. Got +mana, mana on kill, and some fucking miracle gave me T1 all resistances which I wanted.

How should I proceed without needing an omen of light? I had 150 divs and now down to 78. Obviously I’ll desecrate with an echo, but not sure of the goal?

t1 increased % cold damage would be great, but not sure if I’ll hit it. I saw there’s a prefix kurgal modifier I can try for; 15-25% increased spell damage while on full energy shield.

I guess my q, is that worth going for? And maybe hope I hit % increased cold? I absolutely want to avoid any + damage to attacks options.

Sorry for the long read, looking forward to your alls advice.
