Keep in mind that monsters are worth more EXP and have more hit points when 2 or more players are in the same game, but also will have the usual penalties applied, so high-level characters will only obtain a small amount of EXP for killing low-level monsters. It's also worth noting that only teammates within 2 screens of the killed monster will gain EXP. This amount will be divided evenly among all party members, and each member's share is equal to the member's level divided by the sum of all members' levels. The total amount of EXP gained for killing a monster will increase by 35% when a teammate is in the same-named area. The way EXP rewards work means that the lowest level player gets the biggest share, but only if the enemy killed is no more than five levels higher than the player who kills it. In general, it’s better to play online in order to level up fast, especially with a full party of four, and ideally with three other players who are higher level than you, but not that much higher. Here is everything you need to know to know the fastest way to level up through the D2 Resurrected.
