Meat Shield

A Meat Shield can be several things.

If you're looking for the job "Party Tank", that's on An Adventurer Is You.

If you're looking for the stat setup that the Party Tank uses, see either Mighty Glacier or Stone Wall. Lightning Bruiser for the overpowered ones.

The Webcomic is at Meat Shield (webcomic).

For when somebody uses another person as a shield, that's either Human Shield or Bulletproof Human Shield, depending on what happens to the victim.
