Grub enemy line

Grub, Worm and Acid Maggot are species of monsters found in Golden Sun. These monsters, resembling small worms armed with a spear, are palette swaps of each other and have differing levels of power and defense. This is one of few monster lines where none of its members appear in Golden Sun: The Lost Age.

Grub
A Grub is a light green member with a yellow underbelly. Grub has 102 HP, 154 Attack, 32 Defense, 52 Agility, and 1 Luck. It is evenly, but poorly, resistant to Mercury, Jupiter and Venus-based attacks and weak against Mars attacks.

Grubs are about as basic an enemy as can be fought; it can only attack with a physical attack and flee.

Felling a Grub yields 62 EXP, 88 coin, and sometimes, an antidote. Grubs are fought in the Lamakan Desert and are easily the weakest enemy there.

Worm
A Worm is a green member with a blue underbelly. Grub has 132 HP, 196 Attack, 51 Defense, 79 Agility, and 2 Luck. It is evenly, but poorly, resistant to Mercury, Jupiter and Venus-based attacks and weak against Mars attacks.

Acid Maggot can use a physical attack and Search for Help, which summons a new Worm to join the fray. They can't flee from battle.

Felling a Worm yields 60 EXP (startlingly less than the weaker Grub), 99 coin, and sometimes, an herb. Grubs are fought in the Altmiller Cave. Like the grubs before it, its not a very dangerous monster.

Acid Maggot
An Acid Maggot is a pink member with a green underbelly. Acid Maggot has 160 HP, 255 Attack, 60 Defense, 78 Agility, and 2 Luck. It is evenly, but poorly, resistant to Mercury, Jupiter and Venus-based attacks and weak against Mars attacks.

Acid Maggot can use a physical attack and the monster skill Acid Bite, for enhanced damage to a single target, with the chance of inflicting poison. They can also attempt to flee from battle.

Felling an Acid Maggot yields 86 EXP, 102 coin, and sometimes, a Sleep Bomb. Acid Maggots are fought in the Suhalla Desert. While they are a big improvement over their predecessors, they still shouldn't pose a major threat.
