Is there a setting that can affect the enchantment charges for an enchanted item? Meaning... a Shortsword of Sparks has 300 charges, for 75 uses. Is there a global that can adjust this ratio such that either it would then have 100 charges or that each use would use 3 times the charges per use out of 300 for example? Other than manually going in to just that item and setting a non-auto-calculated value... a global setting for all auto-calculated values to adjust the number of uses as a function of charges or number of charges as a function of the strength of the enchant?

I tried messing with some settings with the keyword "enchant" in them, but nothing at all seemed to happen.

The spell that's being cast on strike determines the amount of charge per strike. "Sparks" is a low-level spell, so it doesn't do much damage, or use up a lot of charge each time, in your example 4 per hit. A weapon that does more damage per strike would use more charge to do so, and that would be achieved by changing the enchantment applied to a higher-level one.

The two variables are the total charge, and the cost of the spell being cast on strike. The number of uses is calculated from those. If you wanted to have 100 uses from a total charge of 300, then you'd have to find a spell that costs only 3 per strike (and there may not be one below Sparks). When you enchant an item in-game the same applies, but the spell is custom-made from the altar settings, and the cost per charge calculated from the damage, so there are more levels available then the pre-built ones in the CS. You can add more Enchantments if you need something in the gaps between the built-in ones, too, but it's rarely needed. It's easier to turn off auto-calculation when you need something special.

There are game setting factors involved in the ratio of damage to magicka cost/charge but they affect all spells, not just weapon enchantments, so changing those makes it a larger can of worms.

Thank you for the reply and clearing that up for me. So the enchantment values are tied to the magicka values. That's interesting because I was looking for a way to bring enchanted items in line with my settings from my Supreme Magicka settings for cast spells. I like to turn things up to be brutal for me and my opponents, so I also increase the cost of spells along with their deadliness. This isn't a request for help with SM per se, I didn't really expect the SM ini to take care of this for me, but now that you have let me know that (in theory) the enchantment costs should be affected by the spell costs... I wonder why this doesn't work. The values in the SM ini are:

setGS fMagicRangeTargetCostMult
setGS fMagicDurMagBaseCostMult
setGS fMagicCostScale
setGS fMagicAreaBaseCostMult
setGS fMagicCasterSkillCostBase
setGS fMagicCasterSkillCostMult

Are these settings the ones I would change directly in the CS such that if I increased them it should increase the charge cost per use for enchantments? These settings worked to increase the cost of spells when I increased the setting via the SM ini, but did nothing to increase enchantment costs.
