In Monster Hunter World can all weapon types do a jumping mount attack? I've been toggling back and forth between gun lance and twin blades and I don't seem to be able to mount with gunlance which I guess would make sense given the way the weapon works but it would be handy? I'm also not beyond thinking its just bad timing/luck on my end.
Yes, every weapon can mount and has special attacks while mounted (the gunlance for example stabs the monster and then does a full burst).
That said, not every weapon type can just jump and perform a mounting attack and you need to use the environment to get airborne in order to perform mount attacks.
Everyone can jump off ledges, use slopes, wallvines, climbing vines, and even other players (greatsword launching attack) to get up in the air for mounting attacks.
There are also armor skills and charms that can help with mounting (instead of landing 3 mounting attacks, you only need 1 for example). Check with the smithy on which armor piece has this skill
I haven't used it, but there is also a mantle that apparently really helps with mounting as well.
Personal anecdote: I main gunlance and almost always get the most mounts per hunt(unless there is an Insect glaive user in my group)
Yes! Every weapon is capable of mounting a monster, however not every weapon has a standalone jumping attack (required to mount the monster).
Still every weapon is capable of doing a mounting attack when either:
- Jumping off a ledge / wall
- Sliding and connecting into a jump attack.
Whenever you perform an aerial attack on a monster you will do "mounting damage". Once a certain amount of mounting damage is dealt you will automatically mount a monster.
Note that it's "easier" for certain weapons to reach the mounting damage threshold. A Greatsword might only require 1-2 jumping attacks in order to mount the monster (since it deals way more damage per hit) while it might need 3-5 jumping attacks with dual blades.
Also there are some weapons that can do standalone jumping attacks (Lance or Insect Glaive for example).
As explained in other answers, every weapon (even a bow and a bowgun) is capable of performing jump attack and/or sliding attack.
However, some are capable of jumping out of nowhere to mount even on unfriendly terrain, and here is the exhaustive list.
- Sword and Shield can perform Jumping Slash as a combo from Charged Slash. Note that Falling Bash does not allow you to mount.
- Lance can jump out of its lance charge and perform an aerial thrust as a jump attack.
- Insect Glaive, of course, has its vault and falling attack.
- Bow (yes, BOW) can Charge Step-forward and thrust with its arrow. Although the jump height is too low to pull off unassisted mounting under normal circumstances, monsters with low height (e.g., Tobi-Kadachi) or sloped terrain will grant mounting.
Also, keep in mind that there are some aerial attacks which might seem as mounting attacks, but actually aren't. For example, Spirit Helm Breaker of a Longsword will not contribute to mounting at all.
