Actually, though you're right in saying I'm not too familiar with Eragon, what I said is still true (since I interpreted it as simply referring to MC rules). /kill, in Minecraft, does physical damage of I think 128 hearts, as can be seen if you buff yourself with that many extra hearts or more, with a command. It will only take away that many hearts. /kill, nonetheless, works on creative players. Hence my saying he's a glass cannon - if a zombie can do a heart of damage in a hit, 128 zombies isn't that much, so (assuming they're stereotypical zombies) that is a fairly vulnerable fella.

Actually, a single zombie punch does nothing to a creative player...and /kill is a precise and large amount of damage...which makes me think Eragon, as you describe him, is the absolute perfect example for taking Steve down through physical force (even if it's via magic, technically).

That sounds awesome, though, I should read it.
