R99-grade Amaranthine weapons can now be upgraded and strengthen with PvP (Dark Amaranthine) or PvE (Bloody Amaranthine) options and color effects.
To upgrade an Amaranthine weapon, visit Blacksmith of Mammon and bring your regular Amaranthine weapon, Giant’s Energy, Energy of Destruction, and the desired type of Amaranthine Enhancement Stones. Amaranthine Enhancement Stone - PvE can be acquired through the Tauti boss battle. Amaranthine Enhancement Stone - PVP can be acquired through the Castle Siege campaign, Retrieve the Stolen Taxes. See the Energy of Destruction and Giant’s Energy section for details on how to obtain these items.
Crafting requirements include:
Characters level 85 and higher can acquire Energy of Destruction through hunting in certain zones and completing certain daily quests. You can acquire Energy of Destruction items faster when hunting in a party rather than hunting solo in these zones: Bloody Swampland, Harnak Underground Ruins, Seed of Annihilation, Seed of Annihilation: Battle in the Nursery, Fairy Settlement, Orbis Temple, Garden of Genesis, Seal of Shilen, Seed of Hellfire, Guillotine Fortress, and the Altar of Evil Spirits.
Giant's Energy can be purchased from a Clan Hall NPC or acquired as an Olympiad quest reward.
