Guide:Ocram strategies

Threat Identification

 * Ocram spawns Servants of Ocram throughout the whole battle. They can be deadly if not killed right away.
 * Ocram has two stages like Eye of Cthulhu, but shoots lasers in one or the other.
 * Ocram's hit box is very weird some attacks will fail to hit him. To avoid this aim for his eyes they always take damage

Ranged Weapons
An Unreal Megashark with Crystal Bullets can work well, just make sure to aim for his eyes.

Use Chlorophyte Armor (the ranged set) if you want to defeat him. Otherwise, use Hallowed Armor (ranged set).

Melee Weapons
Shoot him with a sword with ranged capabilities (Terra Blade, True Night's Edge, True Excalibur, Beam Sword). Boomerangs such as Light Discs or Bananarangs work well.

Use Chlorophyte Armor (the melee set) if you want to defeat him. Otherwise, use Hallowed Armor (melee set).

Magic Weapons
A Rainbow Rod can work well, or use a Magical Harp if you want to kill the servants and hit him.

Use Chlorophyte Armor (the mage set) if you want to defeat him. Otherwise, use Hallowed Armor (mage set).

Accessories

 * Star Veil or Cross Necklace

The Fight
Take of any items that provide immunity to Hellstone and Meteorite, then place some hellstone or meteorite and grapple to it. Then use the Suspicious looking skull.
