These skills change the method of delivery for a spell, but they are still, thematically, the spell from memory. Are they compatible with Powerful Meditation or Enhance Sig Spell?
It almost seems like there should be a matrix created that clearly articulates what combinations of skills/abilities/HM/rituals/meditation are valid.
The same answer for Combined Strike goes here: "A spell is "in memory" if it's memorized and listed on your Battleboard. You can cast it by speaking the incant and throwing it, or manifesting it via High Magic like Spell Augmentation or Elemental Augmentation. You can use a spell "in memory" via Combined Strike, but once you're using Combined Strike it's no longer being cast as a spell "in memory" - you've converted it to a Combined Strike spellstrike. Potency won't work on it any more, nor will Enhanced Signature spell." High Magic that says "spell in memory" works on things being thrown that you've memorized. Once you swap it up through another skill, you can't use those High Magics on it. Just like you can't Elementally Augment something you're using with Combined Strike, you can't Enhance Signature Spell it, or Powerful Meditation it. -Bryan Gregory ARC
