"Through the power of darkness comes a upgrader so overpowered it is classified as end-game. If you don't upgrade a drop before using this device, it will multiply the base value as well."
Crimson Force is an item obtainable in the Mutated Emerald Pack, Progression Pack and Diamond Pack. The ores get sent to the abyss and if the "ore is worthy enough" the value will be doubled. It has an apply limit of 19. This means the value can be upgraded with 524,288. However, the upgrader can only upgrade one drop at a time, with a short delay with each upgrade; around .5 second. This will also randomly destroy drops that pass through it. If a drop is attempted to be upgraded a 20th time by this upgrader, it will always be destroyed.
NOTE: If the Crimson Force is used before any upgraders it will not only increase the value but also doubles the BASE value. This can be good for items that require a higher base value then the dropper can produce!
Although the Crimson Force isn't good at early to mid-game content, it is very useful to get the Supreme Pack and beyond, and is MANDATORY to get the cash for the Corrupted Alchemy Pack if you don't have any Diamond items.
This is one of the first persistent obtainable items in the game that you can obtain to get into the Advanced tier in Extensions. However, be careful if you use it in a setup to reach the Entropic tier, if you upgrade over into the Entropic tier and you haven't used the Crimson Force and put an ore through, the Crimson Force will blow up and disappear from that save until you go into a different save, where you can access it again.
Unlike other upgraders, the crimson force can be modified in height, but its upgrades cannot be seen by the Quick action key (Left Shift).
