The shackles are the only way to beat him. Pick one up and aim at him. When he raises an arm there will be a purple aura that'll appear. Throw it at the aura and it'll latch on. The timing window for this is wicked small. Repeat for the other 3 arms and then throw the final one at the aura that appears above his head. Very, very easy boss. The oracle fight is the trickiest of them all but I found a trick that let me beat her in a minute.
