Garden Guard:
Firstly, no one can enter unless accompanied by a Kamael. Secondly, you must be at least two in number. Thirdly, you must be sufficiently skilled to undertake this test, but not so overqualified as to make this test meaningless. Last -- but certainly not least -- any Kamael who wishes to take the test must first obtain permission from the Hierarch. Have you met all these requirements?
(In order to challenge, you must be pursuing a quest or belong to a party with at least one Kamael member, and all party members must be between levels 15-22 and not have completed the 1st class transfer.)
Say that you are qualified.
