Obojo I have had a few people ask me this. A 40% chance to retaliate is important, however because of the nature of flame shield scaling you SHOULD be able to work the build functionally without the idols. However, you will be missing out on not only significant damage, but also ward generation. I have less than a dozen people in my community playing the build that either lack the idols completely or just poorly rolled and they’re doing ok. For end game push, you really need the idols.
