PSA: You can get stacks for devourer by killing/assisting champions

It's considerably less effective for stacking than farming the jungle and far riskier.

While Devourer junglers should be looking for ganks when they can, most of the champions have lack-luster ganks anyways due to the nature of their kit.

Farming is generally a more reliable source of gold and experience so that they can safely reach their power-spikes.
