[Relic] Upgrade

Make Relic Property Skills more powerful!

Relic Upgrade can be found in the lower right corner of the game screen in [Relic] > [Upgrade],
and you can use Relic Crystal to upgrade Relic and acquire upgrade options.

Relic Crystal can be acquired through Blood Castle content.

When upgrading a Relic, the property skill level rises for every certain number of upgrades, 
and the higher the property skill level, the stronger the property skill effect.

Also, when a certain Upgrade level is reached, you can upgrade it to a higher level through Upgrade Promotion and Relic Awakening.

Relic Upgrade Promotion can be done by using Divine Markings,
and Divine Markings can be acquired through Solo BOSS content.
