Necromancy

Necromancy is a game mechanic where absorbed souls from undead mobs can fight for the player. Several items in-game allow the player to store more souls while some armor pieces buff the summoned mobs.

Items
Items with the new necromancy mechanics are:


 * 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 HP, base damage, and level. It is sorted ascending by HP, followed by base damage, and lastly level.

As a rule of thumb, every mob soul can be obtained where the smite enchant would take effect. So every SkyBlock mob based on a Zombie (Lost Adventurers and Shadow Assassins count as such), a Skeleton, or a Wither Skeleton count.

It's harder to get a soul from a mob the higher its level is.

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% or something like that). 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 (Lvl 123) for ranged combat and the Zombie Lord (Lvl 150) for melee. It is safe to assume that there are even better ones under the Mini-Boss category, but not much is know 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 Necron boss fight.

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

How Can I Help
To contribute the stats of unknown souls there has been created a Google Form to collect that data https://forms.gle/2Eh3DbSyH3JAztk19.

You can see the results in a spreadsheet over here: https://docs.google.com/spreadsheets/d/1QpKxEMTAgY70IDvY9pWv5c2r26mms0oqOt0VBhug4J8/edit?usp=sharing

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.
 * Outside of dungeons, summoned mobs will 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.

Trivia

 * Goons were only obtainable during the Dante Event for 30 seconds to 2 minutes, making them one of the rarest summons.
