You could've made the requirement "has opened stage 11 armory chest" and added 100+ Jewels. After all the solid amount of TT gear, hundreds of elements, upgrading material, weapon skin, exp charms you only get 10 jewels in contrast, yikes what a sad finish. Still if you made it to stage 10+ you couldn't complain since its free stuff but if you are a new player this is something you will see often in the future with this company.
