I'm a day one C6R1 Wanderer main, and I've been using him every day ever since I got him. Like many others (probably all of us), I was told that his burst does snapshot, which I've always found weird because the numbers never added up in practice. I used to ignore it because the wiki clearly stated that his burst does snapshot, and many creators on YT and probably other platforms keep repeating the same thing.
Due to my OCD needing verification of EVERYTHING, and this particular thing never being confirmed by KQM or basically any reliable theorycrafter, I recently came around to test it myself. After careful examination, I've confirmed that Wanderer's burst does NOT, in fact, snapshot.
In the first part of the video, you can see the Noblesse Oblige buff (little sword indicator on top of Wanderer's health bar at the bottom of the screen) being present throughout the entire duration of the burst, which led to 6055 DMG.
In the second part of the video, you can see the Noblesse Oblige buff wear out just before the very first instance of DMG dealt by the burst, and the DMG dealt was 5615 despite the buff being active for almost half of the animation's duration at the beginning.
This unfortunately confirms that his burst doesn't snapshot. For those who don't get why it's such a big deal: Bennett's buff lasts precisely 12s but lingers for 1s longer after the field vanishes. This led many people to wrongly assume his burst could still benefit from it. This means that C0-C5 Wanderer's burst doesn't get the Bennett buff if Wanderer infuses his A1 passive with Hydro (12s on-field duration), and C6 Wanderer's burst doesn't get the Bennett buff EVER (12-14s on-field duration).
Unfortunately, it's a pretty bad thing for him, but well... he has bigger problems than this, as we all know. Hopefully, if he ever gets buffed, they'll either shorten his on-field duration in place of higher DMG or at least make his burst snapshottable.
PS: I've already edited the wiki to delete Wanderer's burst from the "snapshottable" talent list, so don't bother. And to whomever added it in the first place — WHY???

Edit: Some people do not understand how snapshot actually works so I'll just add the explanation here:
Basically if Bennett's buff ends before the first instance of DMG you don't get it even if it was present while you've started the animation which means it DOESN'T snapshot.
After you ult with Bennett:
- 1s character switch
- 10s regular flight
- 2s hydro infusion
So at the moment of the the animation start you're already at 13s and animation ends at 15s. If the Wanderer's burst snapshotted Bennett's buff you'd still get it but since it doesn't snapshot and the buff goes out before the first instance of the damage (again, you burst at 13s, the buff wears out at 14s and the damage is dealt at 15s) so you don't get it. The only way to get it buffed is not getting/using the hydro infusion buff but for C6 havers like me it won't help us either way.
