Goblin King

The Goblin King is a goblin sorcerer in Final Fantasy Crystal Chronicles, setting up base in Goblin Wall. He leads the legion of goblins which infests the Tipa Peninsula. He is one of the weakest bosses in the game, but proves difficult to beat due to his ability to teleport around the area and his high amount of supporting goblins. He primarily attacks by casting spells, meaning the players are able to evade most attacks with ease, but his minions will make it harder to avoid damage.

Attacks

 * Staff - Simply, the king will hit you with his staff if you get too close too him. It's fast and knocks you back, meaning the best way to approach him is when he is preoccupied with something else.
 * Bio - Similar to the attack which the ochus of Mushroom Forest, the Goblin King can summon a green bubbling orb which explodes, dealing light damage and  poisoning anyone close enough.
 * Firaga, Thundaga, and Blizzaga - The Goblin King also uses elemental magic attacks. These are slow to cast but have very wide range and can be devastating if they hit the player.

Support Monster: Goblin
One of the most irritating and difficult parts of the battle with the Goblin King is his horde of lesser goblins which endlessly get in the way of the main objective. They're the same, simple monsters fought in the rest of the dungeon. Taking them out should be easy.

Battle Tactic
The easiest way to win this fight is to destroy the goblins, chase down the king, and wait for him to begin casting a spell. Be sure to lure his magic circle far enough away that you can safely attack him without getting hit. When his henchmen run out, kill them quickly when you get a chance, then go back to attacking the king himself.
