Seasonal Events

to play Seasonal event quests you need archive buildings (1 per event), each of them is available to purchase during the event time ONLY. you will have to earn some event points first to purchase them and then get event materials to build them in your home city. Outside of events, you can buy them from other players either through Global Market or by trading.

 

Items are only craftable or obtainable from exchange during events. You can also buy some on the global market if you don't want to wait until event. Because some items are not coming back or at least rotate each year with additions on top.

Most of the items are not best in slot, so don't feel bad on missing some until they come back. Lots of player like me use them because of the rarity and the fact that I collect a lot of stuff in general. Feel free to ask for advise on gearing if needed.

 

The reason people still play archive quests is that they are 6-day cooldown versions, so they give much more Empire points and chests.
