KCGemini | MHW – Roar dodging compilation *Iceborne edition* @KCGemini | Uploaded October 2019 | Updated October 2024, 11 hours ago.
I recommend watching this video in slo-mo to get the proper times to dodge down.

All of these dodges are done with lance hops because they have slightly less i-frames. If you're inputting any of these dodges with rolls, then you'll have more leeway in terms of getting said dodge to activate. There is no evade+ nor evasion mantles used in this video.

As far as I can tell, only Shara Ishvalda's roars can't be dodged in this way.

Some things to note:

~ * Savage Deviljho and Blackveil Vaal Hazak don't share the same roar properties as Deviljho and Vaal Hazak in base World, as their roars *can* be reliably dodged with base i-frames.

~ * Velkhana's second roar is only done after she does her limit break and loses her ice armor, which means it takes around 8+ minutes before she does this specific roar. For some, she'll be limping or even dead before this happens.

~ * Scarred Garuga's fourth roar is based on a timer (which is around 3+ minutes of fighting it), which is also shared with its third roar; so if it does that specifically, then it won't do either roar for a while. It's also on the same level as Anjanath's initial roar; as in it's very hard to react to.

~ * Rajang's powered up roar will knock you down rather than stagger if not reacted to in time. On another note, Rajang's enraged roar seems to have no noticeable stagger effect.

~ * Gold/Silver's powered up roars actually knock you back wind-wise. If you do a heavy attack at the right moment, then you'll get the same effect as if dodging it.

* This monster list is as of 10/10/2019
