To farm Portal Stones in Lost Ark, players will need to farm-specific enemies in the Rethramis continent in Lost Ark. The drops for portal stones, among other collectibles, seem to be random and not specific to certain enemies in Rethramis.
How to get Portal Stones in Rethramis in Lost Ark?
We managed to get one or two from the Red Whitebeak birds and Toxiclaw Robbers that roam Loghill. But killing enemies you find in the Rethramis continent will have a chance to drop the Portal Stones you need to fill the Adventurer's tome.
The rate the Portal Stones dropped from these enemies is pretty low because they are much later on in the Rethramis Adventurer's Tome, but you counter that you need a lot less—you only need to find four Portal Stones in total.
You will most likely find four Portal Stones before entering into the new region, but if not, you'll undoubtedly spend a lot of time just farming monsters in this area of Rethramis if you want to 100 percent the Adventurer's Tome.
The following other collectibles you need to complete the Rethramis Adventurer's Tome are:
- Regulus Statue Fragments
- Plague Spores
- Book of the Priest
- Grangor's Tooth
- Portal Stone
- Aquilok's Skin
- Bloody Rod
