How to earn Portal Stones in Lost Ark

sportskeeda.com:

Lost Ark is a very popular ARPG that saw lots of success in countries such as Korea. With the new release in the United States, there will be quite a large influx of new players to the game.

These new players will need to complete the Adventurer's tome. One of the requirements to do this is to earn Portal Stones. These stones have a low drop rate but can be collected from certain enemies.

For players to obtain the Portal Stones most efficiently, they will need to farm certain enemies within the Rethramis continent in Lost Ark. While the drop rate of the Portal Stone is a random aspect of the game, players should focus on a few mobs in particular.

These are the 'Toxiclaw Robbers' and the 'Red Whitebeak' bird enemies. These seem to have a better drop chance.

Unfortunately, there is no easy way to guarantee a drop of a Portal Stone upon killing an enemy in the game. In fact, players need to kill enemies on the continent of Rethramis until they drop some.

This could take a short period if luck is on the players' side or could take quite a while if not. This is all due to the random drop rates of these items the enemies carry.

Any players looking to complete the Adventurer's Tome will need to ensure that they collect four Portal Stones before moving on.

The good thing is that players who have to farm the enemies here will be able to collect some additional experience and valuables from the enemies for their troubles. It may be a time-sink, but it will not be a fruitless endeavor.

These Portal Stones can be gained from just playing through the game normally, so players may not need to farm them at all. However, to guarantee the completion of the objective, it may warrant an extended stay slaying some robbers and birds.
