Conjured items degrade twice as fast as normal ones. Matched by name
prefix so any "Conjured ..." item works, not just the Mana Cake.
Wrote the tests first, then the updater. Only the Mana Cake lines
changed in the approved output.
Approved the 30 day fixture output as-is so there is a baseline before
refactoring. Conjured Mana Cake is still wrong here, that changes later.
The approval test was also crashing with "no reporter configuration"
instead of showing a diff. pytest-approvaltests 0.2.4 doesn't work with
approvaltests 19, so pass PythonNativeReporter directly.
