Last War Sarah UR promotion: what happens to her stars and shards?
Sarah keeps her hero level but resets to three stars. Check which shards come back before promoting her.
You have finally brought Sarah to five stars and the UR promotion button appears. Before pressing it, plan for the reset: she returns at three stars and her skills need levelling again. If Sarah is in your main squad, have rebuilding materials ready and choose a time that will not disrupt an important battle.
The promotion originally appeared in Season 4, Evernight Isle. Player guide author Cpt Hedgehog lists two requirements: a five-star Sarah and a Legendary Hero Badge. Server seasons and event availability differ, so first check that the promotion is open on your account.
The in-game confirmation explains the return. Sarah keeps her hero level, drops from five stars to three and her skills reset to level one. Skill Medals spent on her are returned by mail. Wall of Honor shards are returned too, but as Sarah-specific shards. The SSR shards originally used to reach five stars are not refunded.
That distinction matters for universal SSR shards: once placed on Sarah’s Wall of Honor, they come back as Sarah shards after promotion. Keep some aside if another hero needs them. Cpt Hedgehog’s guide estimates 1,600 Sarah-specific or universal SSR shards to take UR Sarah from three stars back to five.
The author suggests timing the promotion around the Alliance Duel hero-development scoring day. If your active tasks award points for spending medals and shards, you can plan the investment, collect the returned materials and then rebuild. The trade-off is that universal shards committed to her Wall of Honor return locked to Sarah; do not spend them there just for points if you need them elsewhere.
For an Aircraft squad, Sarah offers a reason to consider the change: her UR kit boosts Aircraft heroes’ Attack, while another skill increases monster damage for back-row Aircraft heroes. The player screen collected by Cpt Hedgehog shows a max-level skill, not the values of a newly promoted level-one skill. Check your lineup and reserves before deciding when to promote.
