Which dynamic skin upgrades need only one feather?

Hello, holiday static skin upgrade only needs 1 feather.

As long as you have the static state, you only need 1 feather to upgrade the dynamic state, which means that this festival has brought 22,223 feathers.

It's just that after the holiday, 1 Yanling upgraded to quietness, such as the epic of the vernal equinox and the Spring Festival in the Year of the Pig. No matter whether 40000 feathers or 22222 feathers are synthesized at half price, it is static, and then 1 feather is used to upgrade the dynamics. Another epic skin is the dynamic of 4w feather rising.
