The Proto Deathmask is an enemy in Final Fantasy IV: The After Years. Like the Deathmask, it will cast Reflect on itself on the first turn of battle, then Reflect on the entire party its next turn, and then bounce powerful spells off itself, such as Flare, Holy, and Death. While Reflect can be a nuisance to the party, the enemy is not difficult to defeat as it can only hit one character at a time. Reflect Slow off of a party member or use a Spider's Silk to slow the foe, preferably Slow since Spider's Silk are harder to get at this point in the game, and either bounce Flare spells off party members or use Quake for black mages (or Leviathan or Bahamut if using Rydia), while your fighters just use their regular attacks. If the player brought Edward with the Apollo Harp or Loki's Lute, or Cid or Luca with a powerful hammer such as the Sledgehammer, they will be of great use against the foe.
