Heres the deal I still want him able to dish out a'lot of hurt.But he relies on tools to do so, I am going to need resources to justify the various trinkets (like a marble enchanted to explode with a flash of light and bang when thrown) he might use.But beyond that I am not sure really.
What else (I'll take specifics, like the stuff he might have, and the various things he might use them for) do I need.
I think Deadmanwalking put it out there rather well for you. Take full blown Thaumaturgy, add some "refinement" into the mix. I'd say that if you are relying on tools for your own things, then yes, you will want to rely upon focus items, potions, and enchanted items, which will take the slots granted by Thaumaturgy and Refinement.
Well, get Thaumaturgy and either Channeling or nothing at all (nothing if you go with my suggestion), then Refinement several times for Enchanted Items. You'll want very high Lore and a bit of Discipline, but that's all you'll really need.
For a Golem, my reccomendation is Item of Power (the +2 version) granting Channeling (Physical Force) plus a level of Refinement...then everything it does beyond walking around with you is mechanically a Spell effect, and it only costs -1 Refresh. This version does require a bit more in the way of Discipline and Conviction, though.
Okay, now I have to ask: with what you have here, does this "item" basically act as a surrogate body for the owner, requiring the use of Channeling (granted by the item) instead of the caster's own talents?
Would it also be possible to create a golem with a similar approach using Enchanted item slots?
Additionally, don't you need knowledge in the correct field in order to use Evocation effects in Enchanted items? For example, could someone create something similar to Harry's Force Rings without Spirit Evocation?
Not sure if I misread something or my brain just threw something in there that wasn't meant to be.
Buy channeling instead of evocation, modeling his limited ability in evocation by restricting him to one element.
You will need full Thaumaturgy, since he should be able to summon(Golem) and enchant things in a variety of ways.
Buy lots of Enchanted item Slots for him to play with.
If the Golem is something he has always with him. Then you should make it an aspect, and maybe even pay some refresh for it, though i couldn't tell you how exactly. Haven't thought about minions much until now *g*.
But it's basically a summoned creature.
I'm not entirely certain if a Golem in this sense is a summoned entity. The Golem-type he is referencing seems to be from Jewish Folklore, which is a guardian made from stone, granted great power but is often lacking in intelligence and direction. Unless the body is just a construct for a more intelligent entity (i.e. creating this body as a vessel for a demon/ghost/etc), I can't see this as a summoned creature.
Anyone is more than welcome to correct me if I am mistaken in any of this.
I'll go with option 3, so can you help me with that please, I dont really trust myself enough to try developing a custom class by myself.
The really neat part of this game is the flexibility of the Templates. As long as your High Concept is fitting, you can technically get away with turning the powers list into a shopping spree. Of course, there are limits, but still entirely doable.
With what you are going for, I'm thinking John Galt has hit the mark pretty spot on, and still left you with enough flexibility to change a few skills around as needed to fit your concept.
