Must be new to the arena, a single prepped attack would cut right through it...

Never mind that Torder can't bleed out possessing no heartbeat, it's limb cutting that's the problem. Which the armor can't counter.

Having armour impervious to anything but a charged attack is a huge advantage, as it does not require any charging or thought at all to work, it essentially gives you a save for any mistake you make while not requiring you to sacrifice anything as it's basically weightless.
