Giant Tooth

Giant Tooth is a Reforge Stone obtained from The Catacombs - Floor VI that can be used to apply the Giant Reforge to any Armor. It grants the highest amount of health out of any armor reforge in the game.

Tips
Giant's Tooth is commonly used on armor sets to give high amounts of EHP. For instance, lower catacomb level players who find themselves struggling may put this reforge stone on Storm's Armor. Additionally, this should be the main reforge if the player is a tank, as tanks need to absorb 80% of their teammates' damage and therefore would need very high EHP - thus, giant is a good reforge on Necromancer Lord Armor or Goldor's Armor. Another good use for Giant's Tooth is on armor with low health but high defense, such as Perfect Armor and Werewolf Armor. One armor that a player should not put giant on is Mastiff Armor, as reforges like Fierce and Ancient will not only provide higher damage, but also provide higher HP (due to Mastiff's full set bonus). This is by far the best reforge for EHP, outclassing Perfect and Titanic.

Trivia

 * It is the reforge which grants the highest amount of any stat, at 240 on a  armor piece.
