Question regarding stuns

So, im doing some theory crafting for next league, and had a question; if i make a high life based character, an use Valyrium and no other ES source, will i get stunned by almost any hit once i get to maps? All the wiki says is that stun is based on max life (i know this is normally an issue for CI with 1 max life), and Valyrium converts this to max ES. If i dont have any other ES source and no boosters, i should only have around 50-100 es. Will this be low enough to make me get stunned A LOT?

Yes. Taking damage that is at least 50% of your relevant pool is a guaranteed stun. That would be 25-50 damage for you, which happens all the time.

However, do note that if you are hit while having 1 or more Energy Shield, there is a 50% chance for Stun to have no effect. This means you don't get that guarantee on a Life Valyrium build for the first (or first few) hit(s) that you take. Once your ES is 0, though, it's guaranteed Stuns all the way to proc-land.
