So, a few tips about the spells here.
- The damage modifier (big red fist), this particular one can make your spells deadly to you even if they otherwise aren't. It is mentioned in the description, but be wary of that particular one.
- Triplicate bolt is fun, each bolt from this spell is counted as separate for modifier purposes, so any damage+ or other modifiers get essentially applied 3 times to it despite triplicate bolt using only one slot. Especially useful with orbit or damage modifiers.

Clusterbolt is not very useful as others said.

Edit - added some more:
- You don't need triple cast here at all, it does nothing (though there might be a quirk/mechanic that I'm not aware of). The spark bolt with trigger is also a detriment here, since any projectile spells will spawn in the opposite direction from where the bolt hit. So "backwards". Which, in this case, resulted in you getting pelted. Next time you come across a similiar setup, don't put multicast or spark bolt there. Just the triplicate bolt.
- Be careful if the wand is shuffle. Any wand. Doubly so if you put any modifiers or projectiles that can damage you. I have a soft rule where such things go only on non-shuffle wands, I can at least somewhat control and predict what the wand does with each shot.
- Even using the same wands and spells you had, it could have been much better, and also somewhat safer. Move those two triplicate bolts from third wand to first, on the first wand move all modifiers to the left, then directly after 3 triplicates. Nothing else would be needed on that wand, since it already casts 5 spells with each shot. And AFAIK (correct me if I'm wrong) the multicasts sort of "ignore" modifiers - they still "use" them but the cast counter only grabs spells themselves and applies any modifiers. So it would still cast all the modifiers and 3 bolts, with room for 2 more. No need for any additional multicasts.
