Shadow Palace

''"A palace created by Marilith's immense magical power. As implied by the name, the beautiful white sparkling exterior, hides the monsters who wander the shadow covered halls within." - ''Stranger of Sword City Website

General Notes

 * Most enemies in this area are the Spirit type, which means they can't be damaged by normal weapons. Magic, offensive consumable items, anti-Spirit weapons, and the Wizard's Magic Weapon skill will be useful here.

Predator of Shadow
Found in Abandoned Area 1 and 2. Not too strong, but requires anti-Spirit weapons or a Wizard's Magic Weapon skill. Calls a lot of reinforcements, so this can be troublesome if you can't kill the other slimes fast enough, or if you don't have long-range attackers.

Cowardly Blue Thunder
Found in Abandoned Area 3 and 4(?) when you ambush and then stay too long in a battle. Not very strong, but is extremely hard to hit. Moreover, it can dispel magic, so buffs and debuffs are of limited use. Attack spells can be more reliable, especially since it's weak to fire. May also be a good opportunity to use attack items.

Golden Magic Knight
Requires the Heart Stone item, which can be found inside ambush chests with the "Trade" insignia (looks like a gem). Labeled as a "Corpse Piece" until identified. Non-unique item, so it can be sold and found multiple times if needed.

Found in Abandoned Area 4, once you have the Heart Stone. Try casting Force Hide and repeatedly walking over the "fire face" visible encounters.

Have high physical damage. Perform several attacks each turn. If these attacks hits the same target, one character can receive more than 400 damage. Have rather high HP. Can cast Magic Break (halves magic power of your party). Call allies (a row of two knights which are four levels lower than he).

Wheedling General
Found in a room on the west side of Abandoned Area 5. Not much to speak of, although its breath attack can be surprisingly strong. It respawns after some time, so he can be killed for easy experience and multiple equipment drops without having to use Morale.
