I already know what my error was - I installed the SkyRe mod and used an old save. Before I did, I had armor that was enchanted with Fortify Destruction in order to give myself free spells. I played the game for several hours after this until I finally decided to change my armor. In SkyRe, this enchantment changes to make Destruction spells do more damage instead of costing less Magicka.
I put on a new set of gear that followed the rules of what SkyRe gives to make the game more challenging, and swapped it with Fortify Magicka gear. Thing is, now all my spells don't do ANY damage.
I suspect that the Fortify Destruction enchantments was used to be my actual baseline destruction spell damage. Therefore, when I took off the gear (adding up to 100%,) it caused mine to be at 0% damage. (I never really had 200% destruction in that case... )
A quick fix is to obviously enchant something to give me 100% destruction.
But I am looking for a more permanent solution to this issue, before I decide to go that route. I am having a hard time finding console commands that deal with actual player character stats.
Thank you in advance
