I'm writing this mainly for myself but also for anyone who's interested
-MILIASTRA WONDERLAND MONETIZATION SYSTEM AND HOW IT WORKS:
>There are 2 banners: Standard and Event.
>Both share separate pities, and have 70 hard pity
>Pity carries over between banners
>Standard has 2*, 3* and 4* items, with 4* items being the main prize
>Event has 3*, 4* and 5* items, with 5* items being the main prize
>Standard Banner pulls cost GEODES. These are obtained for free from quests and shit
>Event banner pulls cost KEYSTONES. These seem to be much harder to get F2P, if not impossible
>When you pull for a NOT 5* item you already obtained twice (once for each manekin gender), you get Materials of that same rarity. These Materials are used to "craft" items of that rarity of your choice. Kind of like a Starglitter recycling system
>Pulling for the duplicate of a 5* item instead "ascends" it, giving you a recolor of it
>Outside of everything I just said, pulling for duplicates also "are converted into corresponding item based on its rarity" (is this outside of the above 2 things I just mentioned? the hoyolab post does not specify)
>These also works as a starglitter-y system (I think????)
>Unused 5* versions of these items get converted into event pulls when a banner ends.
>You can also obtain Lustrous Materials alongside other cosmetic items for free as part of events and the BP
>The paid BP is completely free if you own the base Genshin BP. If you buy the Miliastra BP, the base Genshin BP gets a discount (I believe this means that the Miliastra BP is going to be cheaper?)
>The paid BP gives you picrel. I have no clue what an Event Ode Coupon is, the post doesn't elaborate on it.
