So, I was playing a lot of Dota 2 lately, and I started to wonder about roots and ultimate abilities.

I got curious about whether a root could actually stop an ult in the game. I spent a whole afternoon diving into this. First, I read through a bunch of online guides and forums. A lot of people said roots are kinda like stuns, but not exactly. They stop you from moving, but they don’t always stop you from attacking or using abilities.
Then, I jumped into a few bot matches to see it in action. I picked heroes with strong roots, like Treant Protector and Meepo. I wanted to see if I could catch a hero mid-ult and shut them down.
- I tried rooting heroes like Juggernaut while he was using Blade Fury. No luck there – he just kept spinning.
- Then I tested it on heroes with channeled ults, like Crystal Maiden’s Freezing Field. I threw out the roots, and she kept channeling away, all ice and snowflakes.
- With Warlock used the root ability on him while he was summoning his golem with Chaotic Offering. Made no difference, and his golem still landed on the ground and started attacking.
But here’s the interesting part. When I tried to root heroes who needed to move to use their ults, like Enigma’s Black Hole, it didn’t stop the ult itself, but it did prevent them from moving around during it.
After all that, I realized roots are more about stopping movement than canceling abilities. They’re great for keeping enemies from escaping or chasing, but they won’t interrupt most ultimates. It’s all about knowing when and how to use them.
So, next time you’re in a game, remember that roots are all about positioning. Don’t expect them to be a magic bullet against every ult, but use them wisely to control the battlefield. You should also know that you need to press the stop key which is set to ‘S’ as default to cancel your attack animation in Dota 2.

Hope this little experiment helps you up your Dota game! Keep practicing, and don’t be afraid to try out new things to learn more about how abilities interact.
