Necromancer

The Necromancer 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 (doesnt 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 Paragon 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 a 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 its the prognator with it, or if its the Undead itself with it, i.e, overclocked is bad on the Undead, but great for a prognator, as it can be converted to keep the stat boosts, but not the added ability of constantly losing health, while a modifier like regenerating or flickering is great for the Undead, but sucks to get on the prognator, as it wont give a stat boost, and the ability wont be kept
 * The Necromancer pairs very well with the Engineer as Hex can give Anti Droids modifiers, potentially increasing their effectiveness. In addition, the Hammer utility the Engineer starts with works with Undead Droids.
 * The Necromancer also pairs well with Paladin (because its heal works on the undead), and Angelic Builder (because its paint can improve the quality of the prognator)
 * The stat decrease from the Gray Candy can be mitigated by drinking a Potion of Balance.
 * The Grey Candy Necromancer starts with can be very useful in a dire situation, as while the stat decrease isnt something you'd want, the 75 extra health could prove even run saving sometimes, even if the stat decrease ends up being your downfall

Trivia

 * This class is considered by most to be the best halloween class.
