What is pay to win (P2W)?

Pay to win is a donation shop that gives an in-game advantage: money buys gear, enchants, resources or buffs that are otherwise earned in the game. On such a server whoever pays more is stronger.

The L2OKO server card has a "Donations" field: no donate, cosmetic only, moderate or P2W. The server owner fills it in, so read the donation rules on the project website before the start.
