Bellower is a fantastic void rare champion that can be used as a campaign farmer or as one of the most effective wave control/clear champions in the game. Bellower is extremely versatile depending on how you build him. All of Bellowers attacks are AoE and offer Decrease Defence to your team. Add a stun set to Bellower to make him a really effective wave control champion to help you get through those higher dungeons.
As Bellower is a rare champion he is extremely easy to book out. There are 2 different ways to build Bellower as a campaign farmer – Either build 100% crit and 220+% crit damage or 100% crit rate with 188+ speed. Using the speed build will allow you to hit the waves 2 times before they attack you. This method is far easier to achieve early on in the game.
