Temmie Armor is an armor item sold at the Tem Shop. It is the second most powerful armor in the game, and the most powerful armor available outside of the Genocide Route. This armor is also the only armor not associated with any of the Human SOULs, and the only armor to not have a weapon counterpart.

To purchase it, the protagonist must first purchase "tem pay 4 colleg" for 1000G to unlock the item. The protagonist cannot obtain this on a Genocide Route as the option to pay for college is replaced with premium Temmie Flakes.
After unlocking the Temmie Armor, Temmie explains that while the armor is amazing, it can and will ruin the experience of combat. Temmie recommends that the protagonist buy the armor if they are having trouble with a certain fight only.
9999G is the initial price for the Temmie Armor, but each death reduces the cost (losing battles without dying, such as losing to Papyrus, does not count). The cost of the Temmie Armor stops decreasing after the protagonist's twenty-fifth death.
While the protagonist has the Temmie Armor equipped, in any future fight with a Temmie, the protagonist can spare her from the beginning of the battle, removing the requirement to ACT or attack her.
