Once a survivor hits 5 stars in Last War , they’re usually added to the Hall of Honor / Wall of Honor system, which gives a small global HP boost to your other heroes and lets you keep investing shards to raise that bonus further.

What changes at 5 stars

  • The hero is no longer just a normal upgrade target; it now contributes to your account-wide Honor bonus.
  • Each additional 10 shards can increase that hero’s Hall of Honor level, making the hero a bit stronger and improving the HP bonus it gives to all heroes.
  • At certain milestone levels, extra stat bonuses unlock for heroes of the same type, such as tank, aircraft, or missile.

Practical impact

The biggest benefit is usually account-wide power , not a huge jump to that one hero alone.

In other words, a 5-star survivor becomes part of the long-term growth loop, so extra shards still matter even after max stars.

One example

If you max a tank hero to 5 stars, then feed more shards into the Hall of Honor, you’re slowly boosting your whole tank lineup rather than just that single hero.

Bottom line

So the short answer is: after 5 stars, the survivor gets folded into the Honor system, and extra shards keep giving you incremental stat gains and team-wide bonuses.
