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. Via the Spellbook and by leveling up The Devourer, he can also produce Slime and Darkness in increasing amounts.

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. During rests, the NecroMerger will continue to passively produce resources.

Trivia

 * The NecroMerger's resemblance to Sid is coincidental (and referenced a few times), though 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 Machier 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.
