Necromancy

Necromancy is a game mechanic that allows players to absorb souls from slain undead monsters and summon them. Summoned monsters can then deal and take damage for the player. There are several in-game items that increase the amount of souls the player can store, while some armor pieces buff the monsters the player summons.

Killing a mob with a necromancy item equipped grants a chance of dropping its soul, which looks like a purple head. The higher the level of a monster is, the less likely they are to drop a soul. Only undead mobs and subtypes of undead mobs can drop souls. This includes monsters with player models, such as Lost Adventurers.

Items
Items with the necromancy mechanics are the:


 * Reaper Scythe (3 souls)
 * Necromancer Sword (2 souls)
 * Summoning Ring (2 souls)

To increase the count of the souls any of the above items can hold, there are special Armor pieces such as:


 * Necromancer Lord Armor (+1 soul per piece, 20% mob damage increase from summoned mobs with the full set)
 * Reaper Mask (+2 souls)

Attempting to use an item that has more souls than the player can deploy at once results in summoning only the first few souls that were stored in the item. For example, if a Reaper Scythe has five souls (the last two obtained using a Reaper Mask) and the player does not have any armor pieces that boost the Scythe's capacity, then only the first three souls will be summoned.

Soul Drop Chance
The drop chance of a soul is determined by the level of the Mob it drops from, with this formula: $$DropChance=\frac{100-MobLevel}{100}$$. However, the drop chance cannot go below. A Mob would have a  chance to drop its soul, a  Mob would have a  chance, and a  Mob would have a  chance.

Best Mob Souls
The highest damaging mobs currently known are the Sniper (Lv 123) for ranged combat and the Sleeping / Woke Golem (Lv 100) for melee. The most popular and seen by many as the best souls are Admin (Lv 25) and Hypixel souls (Lv 25). An honorable mention are Tank Zombie souls from Master Mode which are quite cheap and useful in the Voidgloom Seraph bossfight. All of these mobs are obtainable from The Catacombs.

The following two lists are sorted by damage and filtered by best damage for least mana.

Top Souls (Melee Damage)
Show/Hide Top Souls (Melee Damage)

Top Souls (Ranged Damage)
Show/Hide Top Souls (Ranged Damage)

Mana Cost formula
The following is the to summon your captured mobs:

$$\frac{\text{damage}}{50} + \frac{\text{health}}{100,000}$$

Using (-50%) on either a Reaper Scythe or a Necromancer Sword, a [Lvl 100] Sheep Pet (-20%) and full set of Wise Dragon Armor (-33%) this value can be further reduced to

$$(\frac{\text{damage}}{50} + \frac{\text{health}}{100,000}) * 26.8%$$

How Can I Help?
To contribute the stats of unknown souls there are two ways:


 * Manually by filling out this Google Form. You can see the results in the following spreadsheet.
 * Fully automatic using the following Forge 1.8.9 Mod (Hyblock RNG Analyzer).

Bugs

 * Monsters summoned with the Raise Souls ability may fight each other. An example of this is if a Skeleton Master accidentally shoots a Tank Zombie; they might fight and eventually kill each other. This can be resolved by despawning and summoning them again.
 * Summoning an injured undead will heal them back to full health.
 * Before the Aiming enchant was changed into, outside of Dungeons summoned mobs would attract arrows shot from bows enchanted with Aiming.
 * Many summoned souls are Zombies with a Phoenix skin and cannot behave like they normally do because their behavior and appearance have not yet been implemented.
 * During Derpy, all necromancy summons have double.
 * Summoned Star Sentries will take the normal amount of damage instead of 1 damage per hit.

Trivia

 * Goons were only obtainable during the Dante Event for 30 seconds to 2 minutes, making them one of the rarest summons.
 * Rare souls, such as mini bosses, have a darker shade of purple and a glowing skull when the player obtains their soul on the ground.2021-09-23 22.41.14.png
