Get Cyber-Suit Armor
To get the Cyber suit armor, use the Hydrofoil to go to the island called Soldiers Temple. When you reach the island, you'll meet Seth. When you check his stats, he will have the Cyber-Suit armor. De-equip him of this armor and his weapon and just use him as a punching bag for enemys.*Spoiler* {He turns out to be a bad guy a little later in the game} The Cyber-Suit he is carrying will enhance your attack.
