Mappa Mare

Forgeable catalyst with Elemental Mastery as its level-1 secondary stat.
Its R1 passive stacks Elemental DMG Bonus after Elemental Reactions, so its trigger condition is reaction events rather than Iron Sting's elemental-hit condition.
When it fits: Choose it for a reaction-enabled catalyst build and compare the catalyst billet with Prototype Amber or other crafted catalysts.
The tradeoff: One source recipe run makes 1 and lists 500 Mora, 1 Northlander Catalyst Billet, 50 Crystal Chunk, 50 White Iron Chunk at Blacksmith / Forging; 1 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete. Verify diagram/billet eligibility; character refunds and game-specific bonuses are outside base costs. R1 grants 8% Elemental DMG Bonus for 10 seconds per reaction trigger, up to two stacks; a team that does not trigger reactions often gets less value from the passive.
