This is a really simple edit I made. Mysticism adds several new spells to the game and makes changes to vanilla spells. One of these changes is increasing the base cost of summoning Arvak from 136 -> 336, and makes it an Expert Level Spell rather than Apprentice.
While I respect these changes, I do not agree with them. Dawnguard is made to be accessible to early level characters, and lets be honest, Arvak is one of the few good things about the Soul Cairn. I don't want Arvak to be limited to high level mage or conjuration characters. Arvak should be accessible to all.
This mod is a simple .esp (.esl flagged for your convenience) that overwrites Mysticism and changes the Magicka cost, as well as spell level back to their vanilla values. This mod does keep some changes forwarded from Mysticism to keep the consistency of Mysticism (like renaming Summon Arvak to Conjure Arvak), as well as some technical things. But for the most part, the balance is basically restored to vanilla for gameplay.
This file requires Mysticism. As of writing this the newest version of Mysticism is 2.0.6, but this should still work if Mysticism is updated.
