This may be deliberate, but BOTLER's shop (His box) has no items for sale.
I have tried with a toon with Hero merits and the alinement power ten cycle completed and earned.
Tried with other toons, and a help shoutouts response got no positive replies - ie others came and tried for me.
I see from a search that this has been questioned before, but that just became a debate on the value of hero merits
If this is one on those always being asked questions sorry.
