Certainly, but there still are a few bits missing. First, the size of the fireblast is quite an important factor in determining the amount of damage done; second, the exact effects Shadow-weaving are still unclear (to me, at least); and finally, the power of his enhancemet abilities still remains undefined. I would also once again suggest you add a cooldown to his teleportation ability, since having him be capable of avoiding any sort of attack he can perceive is pretty OP.
well, and i can't help but point out that you can't have an increase in force without either mass or acceleration increasing as well. maybe what you're looking for is some sort of forcefield that envelopes the object and pushes away anything else that comes in contact with it. that would make a bit more sense - though ultimately, this is a negligible detail.
Regarding that teleportation bit...what I actually intend is...basically a 2-3 second cast time on the teleportation, plus a second or so completion time, (see Starcraft Zeratul's blink ability from which this was in part based off of) with much faster .5-1 second dimensional shift for the shadow travel ability, (based in part off of the flying thing the Harry Potter Death Eaters do, where they turn into dark magic and fly around, or the zippy lightstream flight form that the angels in Diablo do, for reference). So he is reliant on pure speed and reflexes if attacked with an ethereal attack, as opposed to a physical one, which assuming he had half a second to react, he could dimensional shift and evade. Please note that while ethereal, he can't attack either, and has to...at least in part...come out of shadow-travel, (which is visible) to attack. At all, not just physical enemies...he can't use his ethereal attacks either while shadow-traveling, while magically-based enemies can attack him with ethereal attacks, among other things/enemies. That seem like a suitable set of limitations? High cooldowns aren't exactly well-fitting on this character...
Also, regarding that negligible detail...I am aware of F=MA, however that is why this is magic, not science, it defies the laws of physics. The force-field idea you had is what I use for my sci-fi tech.
I'll have a few more edits made by the time you finish reading this.
