Destiny 2's new Portal activities are peppered with modifiers. Some make your runs easier, while others set out to keep your sorties more challenging. Trade-off modifiers are somewhere in the middle, sometimes offering you benefits and downsides at the same time.
Trade-off modifiers have different effects, but they increase the challenge rating of an activity and raise your enemies' power by 10. If you need a bump to your rewards and don't mind some of the downsides, throw a trade-off modifier in the mix. They're also required to advance past Guardian Rank Six.
