Direct answer: In Anime Warriors 3, a "+1 star" on a unit typically means the unit has one extra "star opening" (an additional active star slot) or a single-star Trait that grants a permanent +1 open to stars—effectively increasing how many star slots on that unit are available for upgrades or draws.

What "+1 star" does in practice

  • It gives the unit one extra open star slot that you can use when opening or upgrading stars, increasing its potential growth compared with the same unit without the +1.
  • Some rare Traits (for example, the "Blessed" Trait) or permanent items (like the Singularity Bow) can grant this +1 star effect either temporarily via Traits or permanently via an earned item.
  • The effect is often described in guides as a boost to "star openings" or an extra open for that unit’s star grid, which helps you unlock higher stats or faster progression.

How players obtain +1 star

  • Obtain the rare "Blessed" Trait by rerolling Traits in Future City through the Bolmy NPC; Blessed grants +1 Star among other bonuses.
  • Farm specific rare drops (for example, the Singularity Bow from the Gauntlet) which grant a permanent +1 star open for your account or unit.
  • Some updates and event rewards can also include star-opening boosts or free rewards that speed up star openings; check the game’s reward menu and update notes.

Why it matters

  • An extra open star slot increases a unit’s ceiling: more star slots mean more stat upgrades or better chance to reach top-tier stat outcomes when opening stars. This makes units with +1 star more valuable for long-term progression and overnight/AFK farming teams.
  • Because Traits that grant +1 star are rare, acquiring them can be a game-changer for optimizing a unit’s performance.

Short example

  • If Unit A normally has 3 star slots and Unit B is identical but has +1 star, Unit B effectively has 4 open star slots to use when unlocking or upgrading stars, making it reliably stronger after the same amount of investment.
