First ticket was Yulan for me. Skill didnt go up, so just the inventory slot.

I will be however sitting on the second ticket for some time, and waiting to use it to as the "4* or three 3*" pull for better gacha chance, when they do something like 11+1 (which they did only once so far... sadly) or smthing.
Still waiting for Wutan to prove if his theory is correct or not.
