Gimli’s attack bonus scales with the amount of damage he can take. Each Citadel Plate then increases his maximum attack by 4. Two Citadel Plates increases his hit points to 13. At 12 damage, he has 14 attack power! This can help tremendously against the Hill Troll and other beefy enemies in the Core Set. Once he takes 9 damage, Gimli has 11 attack. That is enough for him to kill the Hill Troll in one shot considering its 2 defense and 9 hit points. One Citadel Plate and he can even take an attack from the troll without dying in the process.
