Amazing to see this mod being maintained again, it's one of my favorites.

I would love to see better integration with some of the popular fabric magic mods that have sprung up during the absence, such as Archon, Spellblades and Such, and RPG Series mods like Wizards/Paladins.

I see two options for this:

1. Spell Power Attributes support
   Conditionally use spell power's attribute providers (probably Arcane and crit chance/damage/haste), instead of projectile damage. Ideally in this scenario the wand would also give the user varying degrees of base arcane spell power (maybe 2-4 depending on tier)

2. Spell Engine support
   This would be much more problematic to implement, as it would involve rewriting Arcanus' spells to use the Spell Engine API and also changing the book+learning system to use Spell Engine's Spell Tomes and Spell Binding Table. Spell Engine is also ammo-based (runes) instead of resource based (no mana system), which could be a major balancing roadblock.

Archon only uses option 1, which is still a great improvement. I think that would be more appropriate for this mod as well.
