The Seer
From Townstons
The Seer appears in the final group of monsters encountered in Ratsputin's Maximum Security Kremlin. He is an extra large Whisker Seer Hero. When he is destroyed, the Boss Gate will open and Ratsputin and his guards will be released.
Tip: It is smart to leave The Seer to the very end of the group, as killing him early will cause you to be doubly attacked.
