I'm currently working on new class and generic skill-trees for the Arcane Gladiator. I'm also working on a new class called 'Arcane Psion' which - apart from combining arcane and psionic powers - introduces a new resource; sanity.
I'm creating 4 new class skill-trees for the ArcPsion, plus it will share the new generic skill-tree with the ArcGlad.

Here's a brief report of what's being created:-
----------------
Sanity mechanism -- Completed.
Skill-tree, ArcGlad, Level 0: Technique/Showmanship -- Completed.
Skill-tree, ArcPsion, Level 0: Psionic/Egomancy -- Completed.
Skill-tree, ArcPsion, Level 0: Spell/Manifest -- To do...
Skill-tree, ArcPsion, Level 10: Psionic/Psychomancy -- 25% completed.
Skill-tree, ArcPsion, Level 10: Spell/Alteration -- To do...
Skill-tree, Generic, Level 0: Spell/Inversion -- 25% completed.
Lamb roast -- To do frequently...

I'll update this post as I progress; hopefully someone will enjoy playing a character who should never have allowed mana to flow through their brain.
