Demon

• A pledge of several 50+ characters went up to find Demon in the Tower of Oren. The first demon they found was fairly easy and they were able to kill it in 5 minutes, however the second demon they hunted was much harder.
• The damage sustained by demon was greatly reduced by wearing an MR set, however, his punch is extremely powerful. It did up to 300HP of damage per punch, so you can't really fight it alone. The pledge estimated it would take 2-4 knights with condensed oranges to handle just the Demon.
• The Demon also summons. It summoned Lava Golem, Cerberus, Taurverus, Skeleton Guard and Cyclops.
• Demon drops: Tsurugi, Crystal Plate Mail, Old Belt of Soul, blessed Plate Mail, Katana, Elven Magic Gems and scrolls.

Ice Queen

• A smaller pledge of 3, 2 of them with DK morph, went to attack Ice Queen.
• Ice Queen supposedly casts blizzard (as reported on Korean test), but did not do so in their experience.
• Ice Queen endlessly summons clones of herself - the clones hit for about 60HP each. They recommend you use summoned skeleton guards when hunting Ice Queen to deal with the clones.
• Ice Queen drops blessed scrolls, crystal gloves, magic gems and various potions.
