Glimpse of the Past

Cadoc the Belligerent can spawn in four maps surrounding the Castle Ravencaw. Defeating him opens a secret portal that leads to one of the following: Mystra at Night, Wild Forest at Night or Ghastly Grave.

Your goal is to reach Mystra at Night, as it offers the highest progress in a single run. Wild Forest at Night is a decent alternative, but yields less progress overall.

To save time and pearls, use the "alt strategy": as soon as you find Сadok, defeat him once and leave your alt character in map to keep the portal to Mystras open. Since Сadok is a rare spawn, this method makes the whole process much more efficient.
