Players gaining experience will have a higher chance of getting a Random Event. In fact it has been shown that Random Events are entirely predictable, and will occur after a certain amount of experience (around 100k XP) is gained within a certain period of time. During the Bonus XP Weekend, some players gaining in excess of 10 million summoning experience an hour would encounter Random Events with a hugely increased commonality, every 1–2 minutes on average, showing again that the game engine gives Random Events based on experience gain. However, it is possible that there may be other triggers that cause Random Events to occur (such as staying logged in for an extended period of time).
