The Melee Turtle is a Turtle specialized for fighting. It gives the highest damage of all turtles dealing 10 hit points of damage (5 hearts). It was added in Tekkit 3.1.3.
Unlike most killing mob methods, mobs DO drop experience orbs when killed by a turtle, this can be a good way to make a fully automatic xp farm. But the turtle itself will only take mob loot, and the experience orb(s) will be dropped on the ground. The attack command is Turtle.attack() although this might not be the program
