The Trichotomancer:

Trinity Force (Type I) to Trinity Force (Type II)

The Causality Warrior:

Chain Reaction Activity to Causality Manipulation (Ultimate Level)

The Nemesis Genius:

Adaptive Mind to Reaction Adaptation to Superior Adaptation

The Spellweaver:

Spell Manipulation to Magic Manipulation to Magic Lordship

Like Pokemon's evolution? In a journey of growth, adaptation is the best to have.

I was gonna choose Spell Weaver but imma have to go with Trichotomancer

The Causality Warrior seems to be the coolest to me lol, so i’ll go with that.

Magic. Because, whyever not?

Nemesis genius

Forget the development part, spell manipulation is insanely hax and OP on it's own. It's like superpower manipulation but magic version. You could literally create any spell you want, be it a Fireball spell, a telekinesis spell, a mind control spell, a barrier spell etc etc

Spells and magic.

Magic lordship in the end can create effects of any variant.
