Re: Energy Pool
I was thinking because his attack is entirely defense based, even with magic at the squire stage, he would be able to sustain the defense for at most a minute at a time, but maybe use it twice as a squire at most, though it would be dangerous to use it a second time considering the energy drain. At the knight stage, the magic is fully focused in the shield, strengthening its ability to protect and fight, rather than extending very far. Even if he does extend the shield it wouldn't work any differently than the squire stage because the shield itself can now be used as a weapon. I'll clear that up now that I have a better idea of it, if that works!
Re: Area of Effect
Only someone behind the physical back of the shield would be protected, whether Tony is standing behind it himself, or reaching out with it awkwardly or whatever other way he needs to use it in order to use the magic. The barrier extends from the edges of the shield itself, and the shape is defined by those edges and any physical things that block the spread of the magic (a wall, the floor, etc: Tony does not block the magic, though if he's standing on the other side of the shield (holding or touching it from somewhere not right behind it) whatever is beyond the shape of the barrier won't be defended).
Re: Knight Stage
That is exactly what I was going for! I'll make it clearer. ^^
Re: Weaknesses
Yeah, the shield doesn't fully extend around someone, just where ever he's holding it from.
The most obvious weakness is that he cannot attack with his magic, and his shield only becomes an actual weapon at his knight stage. He also has to put himself in harm's way, either by standing behind his shield and in front of the person he's protecting, or by reaching the shield out and leaving himself exposed. This are more... battle hazards than weaknesses, though.
The time limitation and the 'oh crap I have to come up with a way to fight after blocking this attack' are the general draw backs.
As far as built in weakness, though, the magical drain on him depends on how heavy the hit he's defending is: even if his attack is meant to last a minute, it he's blocking something powerful the drain on him could be dangerously significant. The only time this would really come into play, though, is if he's fighting someone of substantial level difference to him (like he's a page and he's taking on a powerful captain/super or general/eternal).
I think that's everything? I'll add what needs to be added right now! ^^
Edit: Oh god I didn't mean to babble that much.
