I am so hyped about new spells. In fact, quite a few of them look very interesting:
ressurection spells: remains to be seen how many dmg they add but if they ignore accuracy checks, could be pretty big. As far as I understand, meele one will hit 0-3 at complete random. So 1.5 dmg per hit on avg. 2.4sec timer on hits. So for example with my 86 magic, I can expect one meele guy to do 31.5 dmg during its 51.6sec alive time. Not game breaking but sounds like nice little extra help!
Vile Vigour - remains to be seen where it will be used but during skilling prayer points conversion to run energy might really come in handy in places where u can recharge prayer easily
ward of arceus - reduced dmg from demonic foes by 25%. Sounds like a thing you could use against cerberus or kril
