There are many Monsters to kill in Lost Ark, specifically in Arthetine. You can find all of the Monster locations below, which fill up different parts of the Adventurer’s Tome.
Where to find all Monster Locations in Arthetine
Arid path - Illegally Modified Weapon Prototype Monster Location
This Monster is located on the east side of the map. This is out of your way, but you won’t have to go very far to find it because there are lots of these here. It is east of Research Camp and southwest of Northeast Guard Post. It looks like a huge, super-soldier robot. When you see a robot linebacker coming at you, it’s safe to assume that’s it.
Arid path - Steel Eater Monster Location
This Monster is located on the south side of the map in Outskirts, south of Research Camp but north of Schreiber. You have to go way to the southern dead end of Outskirts to find it. You’ll have to look for the glowing circle above the head of the Steel Eater Boss, as it looks a lot like its friends. It shouldn’t take you long to find it since we found it so quickly.
Nebelhorn - Deadly Virulent Scorpion Monster Location
This Monster is located on the northeast side of the map, but it’s very out of the way. It is east of the Heart of Sceptrum dungeon past the Hoverboard Lab. The scorpions are red and small; they don’t look frightening, but keep your eyes open for the glowing ball above their heads.
Nebelhorn - Sappy Wallou Cactus Monster Location
This Monster is located on the south side of the map, just southeast of Twilight Hill and south of Nebelhorn Lab. If you’re coming from Scaplands, you’ll have to reach the area this Monster comes from before going anywhere else. You shouldn’t be fooled by the name—this is like a cactus monster. Search for a big, hulking orc with cactus skin.
Nebelhorn - Solitary Goraon Monster Location
This Monster is located on the southwest side of the map, hidden in a corner you’d most likely avoid. This is southwest of Twilight Hill, so if you come from the Scraplands, you can’t take the Twilight Hill route. We have no idea what a Goraon is, but this thing looks like a warthog with arms and a rat body. Moreover, it has horns, making it look like a fever-dream beast.
Nebelhorn - Wanted Smuggler Monster Location
This Monster is located near the waypoint on the northwest side of the map. If you come from Scraplands, we suggest going through Twilight Hill and through the Nebelhorn Lab village. This route has the fewest number of Monsters on the way to this one. This area is full of smugglers who look the same. In the spot marked above, you’ll certainly find the one you’re looking for. Simply look for the glowing ball above the head.
Riza Falls - Dark Red Claw Scorpion Monster Location
This Monster is located on the south side of the map, next to the Stern map marker. You will find it as soon as you enter Riza Falls from Stern, just stay close to the southern edge of the map. The scorpion looks very much like the one above, but its skin is darker. As always, keep an eye out for glowing ball above the head.
Riza Falls - Greedy Royal Commander Monster Location
This Monster is located on the east side of the map, just west of the map marker to Red Sand Desert. It is southeast of the Verdantier dungeon. It seems true that people have found this tank in other places, since they are all over the map, but we found this one here. Just look for a tank; it’s hard to miss.
Riza Falls - Vicious Mercenary Swordfighter Monster Location
This Monster is located on the southeast side of the map. It is south of Verdentie Observatory and west of the Rest Sand Desert map marker. This one resembles a person holding a sword. It has a glowing ball above its head.
Scraplands - DIS_MK-II Prototype Monster Location
This Monster is located on the east side of the map. It is southeast of Hoverboard Testing Site and east of Magick Relay Station. This is a flying drone. It’ll seem strange when you see it, but there are plenty like it around, so look for the glowing ball.
Scraplands - Skilled Elite Smuggler Monster Location
This Monster is located on the east side of the map, right next to the previous entry. It is east of Hoverboard Testing Site and northeast of Magick Relay Station. If you’ve played Metal Gear Solid 4, just imagine a rip-off of the Gekko. It’s a bipedal robot with only legs and a head.
Totrich - Bolchi Boss Monster Location
This Monster is located on the northeast side of the map in Crowbelly Gulch. It is south of Temple of Sceptrum and northwest of Wilderness Area. Prepare to be surrounded by a lot of these walking geckos. They come in packs of roughly seven, so just kill them all, and eventually, you’ll get the right one.
Totrich - Guard Service Officer Monster Location
This Monster is located at the center of the map in Cloud Valley. It is east of Clockwork Square and northeast of Rizen Orphanage. If you want to find this one, look for the glowing orb above its head because these Monsters come in packs of four. Think of them as knights.
Windbringer Hills - Machine Legionnaire Prototype Monster Location
This Monster is located on the northwest side of the map, right next to the map marker toward Stern. It is northwest of Junkyard and west of Guard Post. The best way to describe this one is like a robot with a chainsaw, sword, and shield. It’s a big murder robot. Look for the glowing orb because there are a lot of murder robots around.
Windbringer Hills - Sharptooth Crocodile Monster Location
This Monster is located on the north side of the map. It is north of Guard Post and northeast of Junkyard. This is a high-quality crocodile model. There are a few crocodiles around, so keep an eye out for the glowing ball. We found this one fairly quickly, so you should, too.
