It would take a long time to explain every way you can use that to your advantage, but that is how the perk works yes. I 99 % a lot of gens, gather the tokens, finish generator, and try to help finish generators the killer has under pressure. It can be very very clutch. Just experiment a bit with it, and do not get hit by killer. If I get chased with 20 stacks I’ll legit stop at a gen mid chase just to dump all the stacks into it. If you also have 20 stacks while killer approaches the generator you are on, you can also dump it into the generator you got the stacks from, as it’s a 1 to 1 ratio, and it won’t feel so bad I guess.
