Istredd's shields probably could hold off that many torcainse; not for long, but long enough for them to teleport. They're strong, as this creature is finding out, the banging it is attempting to the shield really doing nothing. It's unfair, but it's the circle of life. Something is always stronger.

It's a credit to his absolute trust in Lucifer that he doesn't question whether that's a good idea. He does what he asks, lowering the shield at the precise moment he asked for, and Istredd reaches over to pull up Lucifer's spear from the dead one. He's been training with Lucifer since early on so he is generally at ease holding a weapon, even if it is not his go-to instinct.

Do you plan on having a wrestling match with it?
