When do rare, high-tier units start to appear in the Shop?
Higher tier (i.e. higher cost) heroes start to appear on the shop as you reach higher levels. This is one of the benefits for buying EXP and leveling up.
These are the significant levels where you’ll start to see higher-tier units in the Shop:
- Level 1 for Tier 1 ($1) units
- Level 2 for Tier 2 ($2) units
- Level 3 for Tier 3 ($3) units
- Level 5 for Tier 4 ($4) units
- Level 8 for Tier 5 ($5) units
