Ok be careful with this.
It seems to work like this.

Whichever Level you are on when you click execute is the level of plans you receive - which is good
BAD THING - as sson as you click execute you are charged the stamina and given the plans. You dont get to chose to say get a chest plan and a relic and only be charged 10 stamina. You get charged 5 stamina for every single boss in that area and are awarded a RANDOM plan form it. I received a sword a relic 4 chest guards and a helmet. AND ALL I DID was click execute to see what it did. I NEVER CLICKED CLAIM

THESE NEW FEATURES AND CHANGES WITH NO ANNOUNCEMENT HAS TO STOP, I just lost 35 stamina for NOTHING
