King of Avalon almost always has one or two seasonal events being active. At this time the Meteor Shower Event is one of them. This guide explains how the event works.
During the duration of the event you receive Meteorites when you are gathering resources. These can be used for rewards.
You get Meteorite when gathering resources. The amount differs quite a bit. On level 6 tiles I have received between 3 and 6 Meteorites, On level 7 tiles between 4 and 7 Meteorites.
You do not receive any Meteorites when gathering on alliance resource tiles.
You get your prizes by selecting the Meteorite items in your items and clicking Use. Prizes I have received include: Gold, Intensity Crystal (I), 100 Lord EXP, 100 Dragon EXP, 10 Assault Power, 10 Guardian Power, 30m VIP, 100 Dragon Spirit EXP, Dragon Spirit Recall, 1k Food, 1k Wood, 200 Iron, 50 Silver, Knucklebone. 5m Speedup, Animal Hide, Cerussite, Pine, Bronze, Cypress, Fluorite, Spider Silk, Soul Clay, Air Stone (I).
There is not much to it, just do what you normally do and collect the extra prizes, the same as several seasonal events before. If you have any questions, or comments, let me know in the comment section.
