Stamina Servers (applies to Korean Seoul server and North American version only):
Stamina is a feature implemented by ndoors to provide a more friendly environment for casual gamers. It creates heavy changes in the gameplay. If you only play for something like 2 hours a day, its a pretty nice feature since no one will really get that far ahead of others. Stamina provides a nice benefit and changes to PvP that aren't featured on the other servers. Unfortunately, if you party, the concept of stamina limiting players becomes ruined due to the stamina regeneration rate in a party.

At the beginning of the day players below Level 50 are given 100 stamina and players above are given 50 stamina. Players regenerate stamina at the rate of 1 every 10 minutes with no combat. Other ways to obtain stamina include giving gifts, sharing monster info with other players, and using the help desk to answer questions (limited to 5 each a day). Players below Level 50 can store up to 120 stamina while players above can store up to 60. When a player has stamina they obtain normal exp and drop rates. When they run out of stamina, exp and drop rates are reduced to about 30% of the normal rate (the North American version says stamina gives a 300% exp boost, but its actually the normal rates of the other servers). If you check the monster info in your database, it gives you the correct amount of exp that a monster is suppose to give you, but stamina doesn't give 300%, it only gives 100%. If you ask me, its false advertising on nDoors' part.

The goal of stamina is to create a linked community where players are likely to interact with each other. It is very focused on PvP. Your division ranking is displayed right next to your name as well so others can see where you stand overall. Stamina has been the source of numerous debates in both the Korean and North American versions of Atlantica Gold. The Korean version basically won the fight against stamina resulting in a single stamina server with 10 non stamina servers. On the other hand in the North American version, stamina won the fight resulting in 3 stamina servers for open beta.

Most of the changes were made in PvP. Equipment and skill level play a the role in determining who is superior. Equipment upgrading is also capped at +2 so a player with +10 weapons can still be beat a player with +4 items. It provides a competition that is mostly based on skill rather than who has the best items and highest level. Even a level 40 player can defeat a level 100 character with this. The second big change is the implementation of auto scrolls. In PvP, an opponent's player is marked with a bonus sign which will automatically activate a scroll when that character is hit. Unfortunately this creates a huge advantage for players using range and area of effect characters as they can affect multiple targets in 1 shot nearly guaranteeing the activation of several scrolls per turn. You also get a "300% boost to exp", which means its normal, when fighting in PvP and can obtain items off of players as if they were normal mobs (other players do not lose their items). Winning a PvP match will also grant you 3 stamina as well.
