A rare event with name changing depending on time of the year.
Example of the Cold Winter event.
How to get it
By killing monsters (either in clan or by yourself), you have a chance of activating this event for yourself. This is not limited to one player, so in theory, a whole clan can get this event per player on a single and same kill, however is extremely unlikely.
Reward
A XP multiplier. Levels under 60 gets a higher percentage of this event happening, but also a higher multiplier. The multiplier is essentially a value that gets multiplied by the xp dropped by the kill. So killing a chicken and gaining 10 xp with a multiplier of 100, would give you 100 * 10 xp.
