Guide:Ocram strategies

Ocram is the second endgame boss on the. Ocram spawns Servants of Ocram throughout the whole battle. They can be deadly if not killed right away. It has two stages like the Eye of Cthulhu, but shoots lasers in one or the other.

The Battle
Ocram's hit box is not very precise, so some attacks will fail to damage him. To avoid missing him, aim for his eyes.

Ocram's second form is extremely dangerous; he'll fire waves of Demon Scythe spells. Their damage can reach 180 in one hit, so make sure to avoid them. He will also fire large laser barrages during this phase, so you will want to have mobility accessories equipped.

Arena Preparation

 * It is advised to have a long, straight platform, with a small wall to block attacks similar to a platform used to fight the Wall of Flesh or The Twins.

Weapons
For Melee users:


 * Shoot him with a sword with ranged capabilities, such as the Terra Blade, True Night's Edge, True Excalibur, or Beam Sword.
 * If you have not yet acquired any of the aforementioned swords, an easier sword to obtain is the Chlorophyte Claymore; it deals good amounts of damage and fires orbs which deal hefty amounts of damage.
 * Boomerangs such as Light Discs or Bananarangs will work well. The Possessed Hatchet will do good amounts of damage with a good modifier
 * If you have managed to get The Horseman's Blade, you can easily kill the Servants with it, and the summoned pumpkins can deal big damage to Ocram.
 * If you can get it, use Turtle armor. Otherwise, use the melee sets of Chlorophyte armor or Hallowed armor.
 * If you have killed him multiple times before and are planning to farm him, Dragon armor is quite effective.
 * You can also use Flasks; the most useful are Flasks of Ichor as they reduce Ocram's defense, and Flasks of Cursed Flames for extra damage.
 * If you are looking for a profit, you can use a Flask of Gold.
 * Vampire Knives are very useful due to their life stealing ability.

For Ranged users:


 * The ranged set of Chlorophyte armor is recommended. If you can't get it, use Hallowed armor instead. Shroomite Armor outclasses both of these, but is much harder to obtain and is only accessible after Plantera.
 * A Megashark or Uzi as well as Gatligator with Crystal Bullets can work well, if you make sure to aim for his eyes.
 * Alternatively, you could use the Flamethrower if you've beaten Skeletron Prime. If you are concerned about your ammo, it would be useful to create a gel farm with a Slime Statue.
 * The Pulse Bow is quite effective, as the arrows bounce off walls and deal large amounts of damage.
 * Using Heart Arrows with a bow that uses more than one arrow such as the Tsunami can stun Ocram, preventing it from shooting or spawning Servants of Ocram.
 * Megashark, Venus Magnum, or Clockwork Assault Rifle can be helpful paired up with Chlorophyte Bullets.

For Magic users:


 * A Rainbow Rod, Magical Harp, or Heat Ray will excel against Ocram, although the Rainbow Rod should not be used while fighting the Servants.
 * If you want to kill the servants easily along with Ocram, use Spectre armor, the mage sets of Hallowed armor, Chlorophyte armor, or Beetle armor.
 * Using a Shadowbeam Staff in an enclosed area can deal massive amounts of damage, as the projectiles can bounce off walls, which also can take out the Servants.
 * Use Chlorophyte armor (with Chlorophyte Headgear) if you want to defeat him. Otherwise, use Hallowed armor (with Hallowed Headgear).
 * Using Spectre armor with the Golden Shower is very useful as it will heal small amounts of HP rapidly, greatly reducing the effect of Ocram's strong attacks. This strategy is more useful on the 3DS version, since the Spectre Hood increases magic damage done instead of lowering it. At times, this is also useful for switching between the Golden Shower and another Magic weapon for even more damage. The Cursed Flames (the corruption equivalent of the Golden Shower) is less useful since the flames are affected by gravity.
 * A Spectre Staff can be very useful if combined Spectre armor (with the hood), therefore healing you bits of life. This is especially useful, as the lasers fire fast and auto-target the servants, quickly dealing large amounts of damage to the servants and Ocram himself.
 * The Inferno Fork is an excellent weapon against Ocram and his servants, as they are not immune to the On Fire! Debuff. It's also useful for getting rid of its servants.

For Summoners:


 * Minions such as the Optic Staff or Raven Staff are effective against Ocram. Another option is the Tempest Staff if you have defeated Duke Fishron.
 * Sentries such as the Queen Spider Staff or Staff of the Frost Hydra are good additional minions.
 * Spooky/Tiki sets can boost both summons damage and amount, but if those are unavailable, use Spider armor.
 * You will want to equip high-tier summoning items like the Papyrus Scarab, Pygmy Necklace, and Necromantic Scroll to add knockback and extra minions to help in the fight.

Accessories

 * A Star Veil or Cross Necklace will help with the servants and lasers.
 * Wear a Cobalt Shield, Obsidian Shield or Ankh Shield to prevent knockback.
 * Use Wings and Frostspark Boots, Lightning Boots or Spectre Boots for increased speed and mobility. Master Ninja Gear or the Tabi can also be useful for dodging the laser barrages during the second phase.
 * If you use magic, a Mana Flower can be helpful. However, the Servants of Ocram often supply you with enough Mana that potions will hardly be necessary. Magic Cuffs can be used in place of the Mana Flower as well, if you want to avoid Mana Sickness entirely.
 * Celestial Stone gives the player many advantages, including 4 Defense, Life regeneration and increased Damage.
 * If you are not using magic weapons, an emblem or Charm of Myths is good.
 * If you use the Fire Gauntlet, Warrior Emblem, Avenger Emblem and Destroyer Emblem with Vampire Knives and melee armor such as Dragon armor or Beetle Armor, the fight will be much easier. if you are fighting Ocram before Golem, use Turtle Armor.

You Will Need:

 * Chlorophyte Shotbow/ Tsunami
 * about 200
 * Frost armor

Preparation

 * Make sure its nighttime when you summon the boss.
 * have potions with you (mainly ironskin, regeneration, and swiftness, etc.)
 * Make an open wide arena to fight the boss, (use wooden platforms and campfires)

The Battle
Spawn the Ocram with the Suspicious Looking Skull, then stun him with your Heart Arrows. Remember to aim for the eyes so you won't miss his hitbox. The Frost Armor adds the Frostburn debuff to the Ocram, allowing you to defeat him in less than a minute. For a video tutorial, see Merrick's Terraria Mobile: Heart Arrows VS Ocram Video.
