Cinematic Spellcasting: At the end of each scene, a spellcaster with any active spells may spend spell points equal to that spell's cost to have the spell automatically "recast" at the start of the next scene, without requiring any action from the caster.
I've used something very similar before - under my version, any spell with an "Enduring" duration tag could be maintained by keeping the spell points to cast it spent. So if you cast Conjure Elemental II, you could keep it around "forever" by having the 3 Spell Points not able to refresh until after you dismiss the spell.
The other two are pretty cool, I'd price Hurtful Healing at 2-3 AD, and Action-Packed would be a Permanent (or 2 AD if you wanted it to have a cost like that).
