You don't need two charges for the skill anon, just run this. All guaranteed relics so no RNG, even.
Double skill is only good as a defensive tool since it has no practical offensive applications, it's not worth it as long as you're even semi-confident in your ability to roll. That's if that situation even comes up, since some bosses are so slow or rely on actually getting to you that allow you to just troll them with one use, like the tree sentinels.
