Necromancy

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

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.

Mobs
This section contains a list of Undead mobs that can be revived, making it possible to spawn them to fight for the player. This list also contains their health base damage, and level. It is sorted ascending by, followed by base damage, and lastly level.

Soul Drop Chance
From a small test series (100 kills for each data point), the approximate drop chance for a soul to be found depends on the level of the mob the player kills. It is currently unknown if there is a cap to the mob level that the player can obtain, if the chance just becomes incredibly low, or if it is capped at a certain drop chance (e.g. it doesn't go below 5%). The highest mob level currently known as obtainable is a Minos Inquisitor with a mob level of 750.

Best Mob Souls
The highest damaging mobs currently known are the Sniper (Lv 123) for ranged combat and the Zombie Lord (Lv 150) for melee. It is safe to assume that there are even better ones under the Mini-Boss category, but not much is known about these, due to their rarity to drop and the low count of those in a Dungeon run. The most promising candidate for the most damaging mob could be the Shadow Assassins in the second stage of the Necron boss fight.

All these mob souls are obtained from Floor 7 in the Catacombs.

Mana Cost formula
The following is the to summon your captured mobs: $$\frac{\text{damage}}{50} + \frac{\text{health}}{100,000}$$

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 Dragon Tracing, 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.
