Quick answer: choose Boons that reinforce the job the build already performs. Start with consistency and survival, then add specialized damage.
Damage builds
Favor effects that match the actual attack pattern: repeated hits, setup-and-payoff, summons, or a reliable opener.
Support builds
Prioritize recovery, resource stability, and effects that remain useful when an ally makes a mistake.
Solo builds
Every slot must contribute to damage, recovery, or route stability. Avoid party-only value unless it also affects the player.
Verify the card
Read the live Boon effect and slot cost. Older exact loadouts have been removed because multiple values lacked stable official sourcing.
