So, I've been playing the CTT for Battleborn, under the NDA, I can't actually discuss anything about it, but theirs plenty on the site and gameplay on the web, and, the site includes her Helix and abilities.
I'd like to base a 20 level class around Orendi. So, here's what I'm thinking so far.
Chaos Mage [Subject to change]
A Chaos Mages primary ability should be Charisma, as it takes a great force of will to channel the raw energy inside if them, and it affects may of her class abilities. Dexterity should be a close second as it allows her to avoid attacks. Everything else is less important, as they do not tend to be in the front lines of battle, and are less reliant on other abilities. (I want to avoid the Issue of MAD)
HD; D6
BAB; Probably Cleric.
Starting age; Rouge
Alignment; Any Chaotic. Chaos mages come from many walks of life, but all are in some way unhinged and border the line of sanity.
Proficiencies; Simple weapons. Armor heavier or shields interferes with a Chaos Mages natural connection to the chaotic energies she channels.
Chaos Bolt: This would function as a ranged supernatural attack, 30 feet, starting at a 1d6 + Charisma mod, gaining power as she levels, in line with, or slower, than a monks unarmed damage, and gaining additional attacks as BAB progresses.
Chaotic protection; A Chaos Mage may add her Charisma bonus, if any (minum 0), to her AC, as long as she is not wearing Armor, a shield, or carrying a medium or heavy load.
Talents; These would modify her Chaos Bolt and other abilities, akin to Rouge Talents.
Shadowfire Pillar; An AoE of some sorts. Full round action?
Padigram Shift; A high level line attack. Powerful, but slow, requires a full round action. (Usable every [X] rounds or once per combat, other restrictions?)
-------------------------------------
I will come back to this tomorrow, and over the course of the next couple of days. After Sunday, I hope to have a friend, or someone from the fourms, to take over on this project, as I leave Sunday, and will not be available agian until the week of Christmas, and later in February, as I will be in Bootcamp.
This concept sounds way too narrow. It looks more like a concept for a specific character rather than a class. If you want to play a magical character with some kind of ranged blast attack, then arcanist or kineticist might be up your alley. That might be the better alternative considering that you don't intend to finish the class yourself.
You pose a valid point and while I'm not familiar with the two, I'll take a look, and do some research and conceptualization, so I suppose the Issue would be thematical, and of course, number crunching. I'll return with my concept.
I'm not seeing anything unique enough to build a class around yet.
