[quote=thewizardguy]Joshua refers to this power as 'Guardian', and can summon/dismiss it at will[/quote]

It can be materialised out of thin air, at will, by Joshua. 

True, it would probably tear instead of shattering if it had the properties of steel. I should probably have had more details on the exact physical properties of the golems, clarifying things like hardness and flexibility.

Yes, the 10 golems are quire powerful. But to be fair, he only gets to do that when he's fighting at least 10 people. If you're fighting him one on one you only have to deal with a single Guardian, which is powerful but generally weaker in combat than other characters. If you think it's too powerful that's fine. But it's not like 10 golems is his 'standard' combat mode.

If Joshua went unconscious I imagine the Guardians would still materialise, but they'd be stuck performing purely defensive actions. Standing around the unconscious Joshua and intercepting attacks, maybe stabbing anyone who got within arm's reach.

Again, if you think it's too powerful I'll happily nerf it.
