0.3.5.1

- Fixed some spells being bugged (Double Shot related)
- Fixed the Invincibility Stone not being un-equippable if you had it equipped before the patch
- Blue Health Orb costs 20MP to cast now, and you won't get MP back if you hit it at the wrong time (I just realized I forgot to change the description though, fixing that next update)
- Made the window to hit it a tiny bit longer
- Also fixed the MP costs on Blue Health Orb, Cheaper Healing should have affect the cost but it was bugged
- Faster Healing will synergize with the Blue Health Orb
- Healing Blast has a synergy with Blue Health Orb
