Sword Swipe	The Iron Giant uses a basic sword swipe that can reach quite far and hurt extremely bad. Its best to stay away to avoid this attack.
Sword Rush	He can sometimes swing his sword and create a long-range spinning projectile that will paralyze anything it hits and damage it greatly. Hop quickly to the side to avoid it.
Sword Slice	Very easy to avoid but has a shockwave effect. He'll rear back his sword and slam it down on the ground in front of himself. It will hurt greatly, stun anything it hits for a decent amount of time and creates a small shockwave pushing back anything it touches. Stand to the side and defend to avoid the shockwave.
Fist Slam	Similar to the Sword Slice in every way except the Giant will use this attack once his sword is broken and he is weaponless. Avoid it like you would the Sword Slice.

Later Cycles: Starting on cycle 2, whenever the Giant is weaponless, he'll cast Gravija which has a wide range and can diminish your health substantially depending on circumstances. His Goblin cohorts will also come out more frequently during the battle, but will most likely be killed off by the Giant unintentionally. The Giant itself gets a noticeable speed and strength boost with each cycle, so be careful!
