The Standard Book of Spells Grade 5 Challenge
Little is known about the contents of the Grade 5 book, apart from a reference to a “Substantive Charm”. Is that a specific charm, or a broad class of charms? Those of us that are not part of the wizarding world may never know.
We do know what is required to qualify for this challenge.
You need to find all of the following:
- 1000x Traditionals
- 500x Puzzles
- 75x Multis
- 25x Letterboxes
- 25x Earth Caches
- 10x Virtuals
The container is NOT at the posted coordinates. You may visit and sign the log at any time. If you do not yet qualify, you may add a “Write Note”, however you may only log a “Found It” if the checker below gives you the green tick, indicating that you have qualified.
There is no need to attach an evidence list of qualifying caches, nor wait for CO confirmation; if the checker gives you a green tick indicating you have qualified, you are welcome to log your find. The CO can independently verify whether success criteria have been met. You must sign the physical log. You may do this before qualifying, but may only log online as found once all elements are satisfied
There is no restriction on found date or location of qualifying caches. Check to see if you qualify for this challenge using the link below.
This challenge complies with the 2016 Challenge Cache Guidelines, which can be found here.
