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.
 * Ocram second form is extremly deadly also.

Strategies
Fly above him with chlorophyte bullets if you are ranged.Melee is preferred with any sword that fires projectiles so that the Servants of Ocram get hit at the same time from the beam.Possibly use frost armor with this so it inflicts frostburn. Mages do the same with ranged,except use a magic weapon.

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 Turtle Armor (if you can get it) if you want to defeat him. Otherwise, use Chlorophyte Armor (melee set) or 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).

Or use the full set of spectre armor with a strong mana weapon or magic dagger

Accessories

 * Star Veil or Cross Necklace will help with the minions and lazers.Obsidian Shield or Ankh Shield to prevent knockback.Wings and lightning Boots or Spectre Boots for increased speed and mobility. A Mana Flower is helpful during the battle but the minions can supply you with enough Mana. Additionally Magic Cuffs can be used instead. if you are not using magic weapons an emblem or Charm of Myths is good.

The Fight

 * It is advised to have a long, straight platform, similar to a platform used to fight the Wall of Flesh.
