Stun Immunity on low life

Hi guys, playing low life for almost 1 month, shavs and other pretty cool stuff you know.
Been a caster for the past week, and felt pretty good with survivability and range kill speed.
The question i have in particular is about stun immunity (from paws, unwavering stance or eye of chayula). Is it really worth? When i can find myself looking to avoid stuns? As ranged character with good mobility never felt like this immunity would change something to me, but i would really like to understand better how it works!
Thanks for the time, and sorry for bad english!

The reason stun immunity is generally valued so highly for ES builds is that stun duration is based on your maximum life. That means ES builds are waaaay more vulnerable to getting stunned than life builds (having any amount of ES gives you 50% stun avoidance but even so). Do you never find yourself getting stunned lots by things like Tentacle Miscreations or other fast-hitting ranged enemies? Similarly, fast moving swarms of enemies like Rhoas or Ribbons are generally fairly scary because they stun you enough to stop you from escaping or killing them.

I'm kind of surprised that you don't feel like it would change much, I can't wait to get stun immunity on most of my builds because it makes the game so much easier.

Being stunned = chain reaction of stuns = you dead.

If you don't get hit in the first place, you're normally fine.

But if you're worried about it, Eye of Chayula is a very good option, OR if your build does elemental damage via physical attacks (AKA WANDER) use an Auxium.

But just like the poster above, it's based on maximum low. Lower the life, higher chance to be stunned.

Auxium doesnt help against stun AFAIK

The problem is, when you get stunned once, it may happen to be not ranged anymore, but melee. Just because a single catch may lead to stunlock, thus urging you to fight the mobs at a closer range. Which will lead to more stunlocks, chain of deaths, frustration, ragequit and flame posts on forum.

Some LL/CI casters, which use skills that allow kiting, can play relatively safe with the Practical Application cluster and ignore stun immunity. For the others, with skills which lock you in place while casting, or low mobility*, or with a skill tree which excludes Practical Application, stun immunity is a must.

*mobility - the deceptive feeling which makes you think you are safe against enemies that freeze, leap and run faster than Usain Bolt
