Dettlaff – The Witcher 3: Blood and Wine

For the first half of the fight, Dettlaff is actually pretty easy. Of course, then he starts throwing heaps of bats at you which can be tough to dodge. The key is to get enough distance on him since it makes dodging the bats easier. Attacking him after this is key but Aard is good for stunning Dettlaff and opening up with a few solid hits.
