Wouldn't appreciate it. Head over to soul wars, pest control, castle wars, pvp/bh worlds, clan wars, mobilising armies (lol)

Yet I see surprisingly many low level accounts with Korasi's Sword in pvp/bh worlds :o

Yeah. When I trained summoning I was looking to get most the most experience out of each charm, not necessarily using them as fast as possible (since that's the quick and easy part of summoning anyway), so generally I would recommend you make the highest familiar available, and save all your blues for Geyser Titans at level 89.
