Merge from Syrrus in /frozentower or /frozenruins. This requires:
Glacera Ice Token x84
Complete Syrrus' daily quest "Glacera Ice Token" by defeating a Frost Invader. This is best done in /frozenruins as there is one right outside of the room Syrrus is in. In total, this will take 7 days for non-members and 5 days for members as they have a quest that rewards more tokens.
