The NecroMerger

The NecroMerger is the first character you encounter in the game and serves as your main guide. Initially, he passively produces 5 Mana every 10 seconds. Via the Spellbook and by leveling up The Devourer, he can also produce  Slime and  Darkness in increasing amounts. The Disco Stone skin for the Tip Stone will also improve his Resource Production. The NecroMerger does not produce Mana, Slime, and Darkness simultaneously - each time he produces a Resource, it is randomly determined which resource will be produced.

Resources can be gained at an accelerated rate by tapping the NecroMerger. After 250 taps, he will need to rest for 10 seconds. The next 250 taps require 20 seconds of rest, and so on. This resets every day. It seems to be scaled somewhat exponentially, as after several rounds, the refresh timer becomes very long. During rests, the NecroMerger will continue to passively produce resources.

Trivia

 * The NecroMerger's resembles Sid which is reference in multiple pieces of dialogue and the former does have a skin to make himself look like the latter.

Rumors and Speculation

 * The NecroMerger's resting period may be reduced by feeding the devourer and merging, although this has not been confirmed.
 * On initial summoning of The Keeper in the Central Chamber, the resulting conversation implies that the NecroMerger tried numerous times to destroy the world and even ran a cult to do so. This implies that the NecroMerger is an alternate timeline version of Sid, where instead of running a cult he was given a lair and devourer egg by aliens to try and destroy the world through it.
