Difficulty Modifiers are an official replay system that increases challenge and reward. Before launch, the safe strategy is to change one modifier at a time so you can tell whether your failure came from the build or the rule change.
What is confirmed
Steam lists Difficulty Modifiers as a way to replay stages with increased difficulty and rewards.
Why add them gradually
Cloudbreaker already asks you to solve movement, damage coverage and grid placement. Stacking unknown modifiers makes diagnosis harder.
Build check
If a modifier increases pressure, spend more grid budget on speed, knockback or Overcharge consistency before adding raw damage greed.
Boss check
Relearn telegraphs under the modified rules rather than assuming demo timings are unchanged.
Release note
Modifier names and exact reward multipliers are not yet supported by the pre-release evidence used here.
