NO!!
The Wight Knight has 296HP.
talk to king schott and offer to beat the wight knight for him. and if you're actually asking where he is, he's in Loch Storn. Go out of Stornway and up the stairs and go North to the bridge. follow the path to Loch Storn
Initially you have to travel further north and defeat the Wight Knight. After this, you can enter the castle anytime during the day, but the doors are blocked at night, so you'll have to go to the inn and return in the morning.
Go back to Stornway Castle, and the King will refuse to give you your reward. Then, converse with the Princess, and go to Zere. Talk to the nursemaid in one of the houses, then a cutscene with the Wight Knight will happen. Go into the forest in the northwestern area, and then go to the blank spot in the middle of the forest map. Brigadoom will come up, and travel through the dungeon. Then a cutscene with the Wight Knight will happen again, then a boss battle with Morag. Hoped it helped! ▲
It is north of Stornway. As you head north from Stornway, before you reach the battle spot for the Wight Knight (the black knight) go left through the fields to a place with about 3 or 4 pillars, if you go there you'll find Zere village, a quaint circular village built around a tree on a rock.
After you defeat Morag,she dissapears and Princess Simona comes in and dances with the Wight Knight.After the dance,the Wight Knight disapears and you have to go back to Stornway to tell tthe King.He says four your reward is the chests at the North-east door and it will be unlocked and you can get the chests.The king also says that the checkpoint to Coffinwell will be open.(The checkpoint is north-east of stornway.)
To find Brigadoom, go to the town of Zere. It's north of Loch Storn where you fought the Wight Knight. Go West from Zere until you find a path leading North. Follow that path North and you will reach Doomingale Forest. Find your way to the ominous black splotch in the middle and you will find Brigadoom.
go to link below
you can make it using the Alchemy pot in the Quester's Rest in Stornway. (go through the whole Wight Knight story to get it). it's in the "items" section
Sadly you can't scout rank S - X monsters , but you can synthisize them you can get a Zoma (rank X) by synthesising a malroth (rank S) and a wight king (rank S) to get a rank X
Go North from Stornway to the map where you fought the Wight Night. Continue onwards, passing by Zere, you'll reach another map where the land is full of purple slime that hurts you when you step on it. One portion of the map is shadowed out, that's the location of Brigadoom.
after you talk to princess simona, go to zere , the city to the north, and go around the tree in zere clockwise. Then go into the house and talk to the old ladies. after they sing the nursery song, then go outside and go around the tree counter clockwise, then talk to the wight knight. after that, go out of the town, then go towards the place to the upper left corner on the map, then go through that place to the smudge-thing on that map, then find your way through that place.
