Build Help for First Leaguer

You need fast metabolism on you amulet if you’re using life to cast

I can tell you that I know added dmg to "attacks" doesn't affect things with the "spell" tag. It would affect the more physical forms of dmg, i.e. from a bow or mace.

I believe you'd need to find just "increased (element) dmg" on rings. Good rule of thumb is if it can roll on your weapon then it should impact whatever skills you're using for dmg.

Damage to attack on your gloves and rings don't scale your spell damage. Also, levels to spell will likely increase your damage a lot, for example in the amulet slot. Look up builds what others do, use the filters to compare similar builds to yours to see what they are doing and how to scale your own damage! Good luck exile, still sane?

You need to cap your elemental resistances. Non-negotiable. Chaos can slack behind a bit until you have more currency. Replacing Gifts From Above with a Rare ring would be a good start.

Regarding Attacks vs Spells - hold Alt when you're looking at something with Dmg Added to Attacks. Hover over the word "Attacks". It says Spells aren't Attacks right there. :)

Should probably replace Morior Invictus with a fat ES body unless its central to your build. The small chunks of Eva and Armor aren't doing anything for you.

I would replace the Bleed/Poison charms with Stun/Slow charms.

Your Cast on Crit gets more energy the more damage you do, which is why its charging so slowly.

Are you following a guide btw? Idk much about Spark COC builds but your tree seems really inefficient and your supports on Spark don't look very good (Blind II?).

Miso recently made a video on PoB2 that might help you out for optimizing damage:
