Assassin enemy line

Assassin and Slayer are species of monsters found in Golden Sun: The Lost Age. These monsters, resembling humans in Arabian-style clothing armed with two daggers, are palette swaps of each other and have differing levels of power and defense.

Assassin
An Assassin is a member with blue and green clothing and red boots. It has 129 HP, 150 Attack, 35 Defense, 84 Agility and 13 Luck. Its resistances are somewhat balanced; it is resistant to Venus-based attacks but susceptible to Jupiter-based attacks.

Assassin can attack with a physical attack and the monster skill Poison Sting, which does enhanced damage to a single target and, as the name suggests, might also inflict them with standard poison.

Felling a Assassin yields 97 EXP, 131 coins, and sometimes an Antidote. They are only located on Kibombo Mountains.

Slayer
A Slayer is a member with pink and purple clothing and green boots. It has 220 HP, 300 Attack, 90 Defense, 158 Agility and 14 Luck. Its resistances remain the same; it is resistant to Venus-based attacks but susceptible to Jupiter-based attacks.

Slayer retains all of Assassin's attack options, but also gains a new monster skill called Kill Sting, which does enhanced damage to a single target and, as the name suggests, might instantly knock them out (fortunately this seldom happens).

Felling a Slayer yields 344 EXP, 254 coins, and sometimes a Smoke Bomb. They are located on the western side of the world map and Shaman Village Cave.

Dark Murder
Like with all other monster lines introduced in The Lost Age that have apparently only two members, a third palette swap member to this line exists in the code of the game cart and was even given its own name, but has none of its stats and abilities coded beyond weak placeholder abilities. Had it been used it would have appeared as a member with purple and brown clothing and green boots named Dark Murder.
