Imagine starting as an Mage, levelling endlessly until you're surprised when the brand new Destroyer class is introduced. You are enthralled by the appearance of it Lost Ark Gold, so you fire up an alternate to try it out. In most games, you'd have to start from scratch and grind your way up from the start when playing in a new class.
However, this is not the case In Lost Ark, where your alt characters are still very tightly linked by your Roster, which means that their overall level will increase as you play, and even buffing unplayed characters, so that when you're ready to switch to a Warrior or a Gunner then you won't be lost in the shuffle. The Roster's level is high, which means boosts to base stats such as Intelligence Vitality as well as Wisdom and Charisma across the board for the characters you have linked to. These boosted stats are sure to come in handy in new game content, such as the recently included Valtan Legion Raid, where you'll require every advantage you have to be successful.
Many of Lost Ark's rewards replenish on a daily basis and rest bonuses are just one of the most frequent rewards. If you're playing with a single account while your alts rest from their time doing everyday tasks You'll earn Rest Bonus points that can be used next time you join. The completion of the Chaos Dungeon or Guardian Raid with more than 20 points on your Rest Bonus meters means higher rewards and double loot, which is why it's always a good idea to have a few characters laying around in the meantime.
Materials and resources are exchanged between characters
In simple terms it is true that an alternate character allows you to earn more money and get more loot. Another benefit from this Roster system is the ability to change items between alt characters, as you want, as long as they're traded and not tied to one particular character. This is basically all the items you collect from Chaos Dungeons along with Guardian Raids, meaning that when playing with your alts you are able to transfer all honing supplies and Cheapest Lost Ark Gold gems to your primary character in order to keep them buff and enhanced If that's what you prefer.
