Necromancer

"The Necromancer kills Droids and revives them to fight for you. Hex the Droids to make your summons even more powerful and choose your summons wisely."

- Class Description

The is an event class from the Halloween Event. While this class lacks any strengths for themselves, they can summon Undead Droids by using their first ability to convert a random droid into one. Choosing a decent droid to convert towards your side and using their second ability to buff them is this class's playstyle.

Strategies

 * The Undead Droid will match the stats of the droid killed using Apparition (includes stat changes from modifiers (does not include ability additions, i.e flickering, or leaking), so it's recommended to hex (check if its worth keeping), and then use apparition on a droid with great stats.
 * Tank, Ardor (especially if you have a way to heal it after activating its ability), Pyro, Cryo, Switch, Rapid-Fire, Vigilante, and Charge Droids are great progenitor droids for Apparition due to their high health and damage stats.
 * Xero Droids are also great contenders, but they must be aggroed first before you cast Apparition otherwise they will not move when converted.
 * If you see a droid you want to convert, kill all the other droids so that the one droid left standing will always to be the target for Apparition. Cast Hex to give the droid a potential stats boost from a modifier, then cast Apparition. The Undead Droid is considered a separate droid from its progenitor, so it's able to receive a modifier by casting Hex again.
 * Try to only use Hex when there are no hostile droids alive in the room that you intend to kill to prevent giving them negative modifiers.
 * Hex can be very RNG reliant as the negative modifier you get is random, and some can even be detrimental.
 * Durable, Flickering*, Regenerating* , Tanky, Dangerous, Violent, Radioactive, and Elite are great modifiers to get as they increase the effectiveness of your Passive Droids.
 * Glassy, Leaking*, Explosive* , Cheap* , and Overclocked* are bad modifiers to have. The effects of Leaking, Explosive, and Cheap can still harm players while Glassy and Overclocked will decrease the lifespan of the Passive Droids.
 * Some modifiers are good depending on if it is on progenitor or if it is the Undead Droid itself with it. For example, Overclocked is bad on the Undead Droid, but great for a progenitor, as it can be converted to keep the stat boosts, but not the added ability of constantly losing health. However, modifiers like Regenerating or Flickering are great for the Undead Droid, but are useless to get on the progenitor, as both will not give a stat boost, and the ability will not be kept.
 * Do not be confused! The special abilities of Flickering, Regenerating, Leaking, Explosive, Cheap, and Overclocked do not affect the Undead Droid unless the Undead Droid was directly given that modifier using Hex.
 * The Necromancer pairs very well with the as Hex can give Anti Droids modifiers, potentially increasing their effectiveness.
 * (because its paint can improve the quality of the progenitor.)
 * does affect the passive ability, but because the chance is so low, gaining it is hardly a priority. In fact, even with (maximum luck), it is still not guaranteed. Likely, but not guaranteed.

Trivia

 * Before 1.7, Necromancers passive was to start the run with Gray Candy.
 * This is the most expensive Halloween class.
