Sacrifice

is a Reset Layer in the Dark Forest. It is unlocked by reaching . Performing a Sacrifice requires having at least 1e9 on-hand Stars. Sacrifice forces a Galactic reset as well as resetting Astral, Stars, Fun, Fun Upgrades (excluding ones in The Funny Machine) and SFRGT. In turn, it awards Dark Matter (DM), which is spent on a selection of the 8 Dark Matter Upgrades listed below. The base DM gain is determined by the following formula: floor(max(0, (log1.05(Stars) - 420) × 1.5 ^ log10(Stars ÷ 1e9))).
After the base gain formula, DM gain is boosted by the following: the 'Flower Dark Matter' Flower Upgrade, the 'It Does Matter' Momentum Upgrade, the 'Normality Dark Matter' Normality Upgrade, the 'Cloudy Dark Matter' Cloud Upgrade, Astral Prestige 1's reward, Grass Jump Milestone 2, the Dark Charger and the 'Solar Powered Dark Matter' Solar Upgrade.

==Trivia==
*A very early version of Sacrifice was implemented in the Version 0.3 - Galactic update. It reset everything the Version 0.4 - Revamp update's variant does in addition to Star Upgrades, Anti-Grasshop Milestones and post-Galactic Rocket Fuel Upgrades. It awarded 1 DM to spend on a selection of 5 upgrades (XP, SP, TP, Stars, Charge).

***At the time, it was highly discouraged from performing a Sacrifice, and anyone who did so likely did not recover for days or even weeks. Some players were unfortunate enough to have timed their v0.3 Sacrifice just before the release of the v0.4 update, the update which, among other things, considerably reworked Sacrifice to be much more rewarding.
**** Sacrifice in version 0.3 used to require . You can technically unlock Sacrifice at this milestone still, but the button is impossible to press.
