To upgrade Orange Heroes in Last Asylum: Plague: Plague effectively, focus your hero fragments and experience items into a single primary carry or tank before spreading resources across secondary squad members. Orange Heroes require rare fragments for star-level upgrades and promotion materials to break past level caps tied to your Sanctuary progress.

Managing Hero Fragment Allocation

Hero fragments raise an Orange Hero's star tier and unlock significant combat power increases. Spreading fragments evenly across your roster dilutes your power, so commit your rare materials to one staple hero at a time.

  • Target Farmable Heroes: Low-spending players should focus on Orange Heroes whose fragments appear in recurring shop rotations and standard event rewards rather than limited-time premium banners.
  • Focus on Core Roles: Allocate your primary fragment reserve to your main damage dealer or primary front-line tank until they reach their next star milestone.
  • Avoid Partial Investments: Save your fragment chests until you have enough to unlock a full star upgrade, ensuring immediate combat gains.

Overcoming Level Caps and Promotions

Level progression for Orange Heroes is capped at specific thresholds until you apply designated promotion materials. These caps are linked directly to your Sanctuary development level.

  1. Monitor Sanctuary Requirements: Check your Sanctuary progress to know when level caps will expand.
  2. Pre-farm Promotion Materials: Earn promotion materials through campaign progression and dedicated resource-gathering missions before starting a hero leveling push.
  3. Maintain Resource Reserves: Keep enough Experience items and Gold in reserve so your primary units immediately hit their new level ceiling as soon as a promotion opens up.

Skill Upgrade Priorities

Skill points and upgrade items are finite, making it vital to prioritize high-impact abilities over minor damage adjustments.

Focus first on upgrading skills that unlock faction synergies or share combined effect triggers between your deployed Orange Heroes.

Resource Allocation Guidelines

Because Gold, Experience, and Promotion Crystals are shared across all heroes, avoid spending materials on temporary characters. A hero qualifies as a staple investment if their utility spans multiple combat formations and campaign stages. If you are unsure of a character's long-term value, hold your materials until you face a progression bottleneck that requires an immediate power increase.
