How do masteries work?

Masteries let you upgrade specific units to their Mastery version for improved stats and abilities. It uses the Uncommon Scroll of Mastery and the Rare Scroll of Mastery.

• Green units: from level 10, 75 Green scrolls and 10 Blue scrolls.
• Blue units: from level 10, 120 Green scrolls and 20 Blue scrolls.
• Purple units: from level 12, 195 Green scrolls and 30 Blue scrolls.

Where the scrolls come from

• 50x Uncommon weekly from the supply token exchange (5 per supply token).
• Honour store: 15x Uncommon weekly (300 honour for the first 5, then 450 each), and 5x Rare weekly (2000 for the first, then 3000 each).
• 350x Uncommon at 200 honour for the first 150 then 250 for the next 200 (does not refresh).
• 17x Uncommon from the Path to War challenges.
• Special events regularly hand out both scrolls.
• 5x Uncommon exchange for 1x Rare at the Mastery Scroll Exchange (Activities tab, hotkey O).

Exception: Mace Sergeants use Uncommon and Rare Scroll of Mastery: Mace Power instead, from the Cadet's Trials tutorial quests (enough to fully upgrade one unit) and the honour store.
