Doppleganger boss on Shadow Casty City's Advanced difficulty

Geez, how long will it be until I convince you guys that the boss for Shadow Cast City on advanced mode doesn't give any experience? I assure you that while my sprite is "equipped," it cannot attack. I assure you that I didn't even have it summoned during all 4 runs. How much time and effort would it take for someone else to confirm this for me? I agree that it doesn't make any sense for it to not give any experience, but it's the truth. I think the table should be updated, as it stands Intermediate is the best setting to do this mission on (as far as the ratio of time:experience is concerned).
