The short answer

Boons are run-specific buffs chosen as you progress through mission areas. The strongest approach is to stack bonuses around a repeatable trigger—such as mark, poison, frost, light attacks, or Angel charge—rather than taking the highest-looking percentage every time.

How boons fit into a run

Boons arrive during the mission flow and disappear when that run ends. Your permanent equipment supplies the foundation; boons bend that foundation toward a temporary power spike. Lore scrolls and the hub’s archive character also connect exploration with pre-run bonuses, so do not treat story pickups as decoration.

Choose a trigger you can repeat

A strong boon does something your weapon already wants to do. Mark bonuses need a dependable way to apply mark. Poison damage needs enough application to matter before a boss dies. Angel-meter effects become valuable only if your normal attack loop activates them often.

A simple boon priority

  1. Enable the build’s main trigger.
  2. Multiply the damage or survival it creates.
  3. Cover the build’s biggest weakness.
  4. Take general value only when no synergy appears.
Do the sentence test: If you cannot explain “this boon activates whenever I…” in one sentence, it may not belong in the build.

Why a high-rarity run can still feel weak

Players often mix several half-finished status themes. That produces impressive tooltips but poor uptime. Commit after the first few meaningful drops, then skip attractive bonuses that demand an entirely different weapon or trigger.

Frequently asked questions

Are boons permanent?

No. Boons shape the current run, while purified equipment and hub progression persist.

What is the best boon?

There is no universal best boon; the strongest choice reliably triggers from your current weapon, perks, and Angel plan.

Do boons affect Angel Mode?

Launch reporting indicates Angel forms inherit build effects, making compatible boon synergies valuable during transformation.

Should I stack one status effect?

Usually yes. A focused status engine is more reliable than several incomplete effects.
