It's the sum of all your Home Village hero levels: Barbarian King, Archer Queen, Minion Prince, Grand Warden, Royal Champion and Dragon Duke. Every level counts as one point, including the level 1 you get for unlocking a hero. Builder Base heroes do not count.

480, which is every Home Village hero at its Town Hall 18 cap: Barbarian King 110, Archer Queen 110, Minion Prince 95, Grand Warden 85, Royal Champion 55 and Dragon Duke 25. There are 113 reward tiers between level 2 and level 480.

Hero levels are capped by your Hero Hall, which is tied to your Town Hall. A Town Hall 12 player can reach at most 210 total hero levels no matter how much they grind, so anything above that needs a Town Hall upgrade first. The planner marks those tiers as TH-locked.

It isn't random. Each hero has a fixed pool, and the tier awards the first piece in that pool you don't already own. If you own all of them, the tier pays 50 Starry Ore instead. When you load a player, the planner names the exact piece each tier will hand over.

Some tiers are quests instead of direct rewards: score 15 stars in multiplayer battles within 14 days, using the named hero or a specific piece of equipment. Completing one pays three Ore Chests; one Shiny, one Glowy, one Starry. Chests hold a range rather than a fixed amount, and the range scales with your Town Hall, so the planner shows the spread for your TH rather than a single number. Players the game considers far behind in the ore economy get a larger catch-up range that we can't detect.
