Some people are getting 0 titanium stones, do you enter the dungeon and click on the red circle in the upper left corner of the screen? If you're paying for Valkyrie's Favor, you can earn 150 every day just by clicking.
As for the gifts, I have been sending gifts to the top titanic stone winners due to the guild policy of strengthening titan, but if guild activity reaches 65,000, I will send gifts to the top 3 guild activity winners as well. This is my decision and may change again when Guilmouth returns.
