Does Kishin Shoukan increase spawn at LHC?

From my experience at LHC, yes it does increase the spawn rate. Interestingly enough, maps ive joined that already had a kanna in it seemed to spawn more when I put up my own Kishin Shoukan.

Like, more than 4 mobs in the map at a time? The spawn of 4's always been the big problem I have with LHC (since in most maps it means you almost never get more than 2 mobs on a platform, so lol mobbing)
