Great Mage

Great Mage is a seasonal event boss summoned on Easter Island using an Easter Key, and it brings the heaviest health pool of any event encounter in the First Sea at a staggering 3.5 billion HP. That figure alone signals what is required: this is not a casual fight. Drop rates scale with difficulty, which means the numbers listed represent a baseline — players willing to attempt harder tiers will see those percentages improve, rewarding preparation over raw attendance.

The drop table skews toward the rare end compared to other event bosses. Spell Echo at 15.68% is the most frequent reward and a genuinely useful item for magic-aligned builds. Ancient Fragment at 5.42% is a crafting component worth accumulating across multiple runs. Below the 2% mark, the drops become aspirational: the Mage Outfit Accessory at 1.43% and Magic Essence at 1.24% are low-probability but consistently desired. The Ancient Mage Title at 0.65% and the Mana Core at 0.52% sit at the very bottom — the Mana Core in particular is likely tied to advanced crafting, making it the priority target for experienced players.

Because the Easter Key gates entry, coordinating key distribution across a group before summoning is essential. Push for the highest difficulty tier your group can clear reliably — the scaling drop rates mean higher difficulty pays off meaningfully for every item on the table, not just the rarest ones.
