Titan Chops are simultaneously a mid- and high-tier food found by slaughtering Titan Beetles, either in the Erebus or potentially in any dimension that you have brought said beetles using a Wand of Preservation.
Raw Titan Chops will grant no negative effects and restore 4 hunger points (2 hunger icons). This is the mid-tier food stage of a Titan Chop. Once cooked, a Titan Chop restores 8 hunger points (4 hunger icons), as much as vanilla Steak or Pork Chops, as well as granting Strength II for 30 seconds. This puts Titan Chops well into the high-tier food bracket of Minecraft, as well as the mid-tier bracket for Potions, of all things.
A single Titan Chop (or two Steak as replacement) is needed for the making of Titan Stew.
