For those who may have seen previous similar threads, after much thinking I finally came up with a solution to my previous problems. With a simple single teleport scroll, and one way teleports, I can force the player to choose between getting one of three potions or any other desired weapons. I've also decided to simply make the potion turn the player into a vampire as an alternative to avoid a non vampire character with vampire powers.
Now just a quick simple yes or not question, VampireChangeEffectScript, is it safe to simply put the vanilla script inside of a potion as an effect? Will that conflict with other mods, or will it work fine?
