Grogar's still pretty powerful without it, he revived Sombra too. It is the source of his greater magic though, he is confident that even the Mane 6 wouldn't stand a chance against him with it. We're not sure the full extent of what it can do beyond creating monsters, but he called it "bewitching" bell so he'll probably put the Mane 6 under his spell like Discord, Chrysalis, and Sombra can do.

The G1 version of Grogar had his power stored in a magic bell as well, which took him a thousand years to make in his imprisonment in the Realm of Darkness, when North Star rings a bigger bell, his bell is destroyed and he is banished again, this time without his army and he presumably is not able to return again.
