Things You'll Need
Instructions
Use the Critical Rate Up ability at the start of the battle. Critical Rate Up greatly increases the chance that your character will perform a critical strike with any attack. Critical strikes ignore armor and kill Metal Slimes in a single hit. Almost all player characters may use Critical Rate Up.
Attack with the Multithrust spear ability. Metal Slimes typically possess between three and five hit points. Their armor reduces most noncritical attacks to one hit point per attack. Multithrust overcomes this by launching three to four simultaneous attacks against the slime.
Choose the Metal Slash sword ability. Metal Slash provides bonus damage against Metal Slimes. Each Metal Slash attack has a high chance to double or triple damage to the creature.
Repeat this process until the Metal Slime dies. Although they possess few hit points, their high armor and evasion rates make Metal Slimes one of the most difficult creatures in the game.
