Ahhh, this makes more sense now, never thought about how using this can allow for being a heavily-armored spellcaster. Players just have to give up a skillset (thereby limiting their utility and versatility) to make the strategy worthwhile.

I find this ends up synergizing very well with gish builds moreso than Leylines because the eventual overkill on mana regen allows one to wear heavier armor and still hit the magic 1/turn cap for sustaining hungry buffs.

If using other mods, there is a strong synergy with the very mana-hungry runecaster, and an extremely strong synergy with Warweaver - Your mana cannot be reduced below the floor established by the class boosts and this provides enough base mana to use all the weaves and still spellcast.

All in all- it has it's own niche in what I select without feeling particularly overpowering.

There's always booze. And Blood Magic's sanguine phylactery. And Night Caps. And the Savvy stat reducing mana usage. Oh, and that Gargle-Galactic Blaster-something that gives you minor Syzygy. And Astrology's greater Syzygy. All great stuff really.

this'd be nice if regen could be >1 per turn
