Killed Drizzt in 3 seconds!!! are werebears OP?

I met drizzt as a lvl 11 Druid Shapeshifter playing solo... summoned 2 werebears with conjure animal lvl 6 druid/cleric spell and than made them attack him. 3 SECONDS later he was dead... yes i said seconds not minutes...

I bet these 2 bears can just solo the final boss and his army lol...
