問題の詳細/Issue Details

Steps:

  1. Equip any Gunlance and proceed to a large monster hunt. We’ll use a Normal Shell Type gunlance vs a Zinogre for the purpose of reproducing the issue, but this issue occurs for any monster. Use a Gunlance that is overpowered against a monster of a lower grade (e.g. Grade 9.5 vs 7-star Zinogre) with Artillery Lv.3 and Partbreaker Lv.3.
  2. At the start of the hunt, aim at the Zinogre’s right foreleg and perform a Rising Slash, Overhead Smash, then Burst Fire to break the Zinogre’s forelegs.
  3. As the Zinogre rolls the hunter’s right from the broken body part, quickly move towards the Zinogre’s tail from its back (evade to your left).
  4. While you’re right next to the tail (within hammer side swing striking distance), tap to perform a quick reload to reload your empty shell magazine, then aim at the middle of the tail and tap three times to perform two normal shelling and then perform a wyrmstake cannon attack.
  5. Observe that the wyrmstake cannon hits the tail just as the Zinogre recovers from writhing on the ground, and observe that the wyrmstake is stuck on its right hindleg instead of on the tail.

Expected:

  1. The right hindleg was nowhere near the point of impact of where the gunlance hit the monster when the wyrmstake staking hit occurred. Therefore, it should not stick to anywhere else but the point of impact of where the wyrmstake ammo hit the monster’s body.

Notes:

  • This applies to any monster.
  • I’m referring specifically to the hit that lodges the wyrmstake ammo on the monster, not the initial gunlance jab.
  • This occurs most easily when you’re performing wyrmstake attack at very close range, and the monster has surface areas of other body parts near to where the point of wyrmstake ammo impact is at the point of sticking.
  • It seems to me that the game chooses the “nearest body surface” when determining where to stick the wyrmstake ammo in when the point of impact clips into the monster’s body, but instead of choosing the closest distance between the point of impact and the hunter’s body (which makes sense, since the gunlance is held in the hunter’s hand and jabs straight into the monster, therefore the wyrmstake must lodge somewhere long the line of the gunlance, which is a straight line from the hunter to the point of impact), the game chooses the nearest surface area on the monster, and that can sometimes cause the wyrmstake ammo to lodge in unexpected players. Often, I hit the tail or the head with the wyrmstake attack, and yet the wyrmstake lodges itself at the butt, the hindleg, or the neck of the monster, or even the wing of Diablos when I wyrmstake the head from the side while standing between the wing and the head. It is very strange.
  • If the gunlance’s muzzle did not clip into the monster at the point of firing the wyrmstake, it will simply stick to any body part that the wyrmstake ammo touches in a relatively forward cone of fire, which makes sense since you’re technically firing an explosive that’s designed to eject itself from the gunlance but not meant to shoot forward like a bowgun projectile, but this also means that the wyrmstaking lodging logic behaves unexpectedly and negatively when the wyrmstake is fired while the gunlance muzzle clips into the monster’s body.
  • This makes the use of wyrmstake for the purpose of breaking specific body part unpredictable, especially when I’m trying to cut tails with it. When it functions as expected, it is actually very good at breaking specific body parts. But right now it’s unpredictable, and I often end up breaking the wrong body part or damaging an already broken body part instead of hitting an unbroken body part.

その他の情報/Other Information

Issue persisted since the release of gunlance. Nothing helps other than standing at a distance so that the gunlance’s muzzle doesn’t clip into the monster at the time of firing the wyrmstake, which is a difficult thing to do, given the lack of precise movement control in this game.

Thank you for your report regarding the Wyrmstake Cannon.

We’d like to start investigating this case, so could you please provide us a video/screen recording showing the issue?

Rest assured that we will look into this once we receive a reply from you. Thank you for your patience and cooperation on this.

Hi @NianticModKKI, sorry to keep you waiting. The issue occurs usually when I am not recording, so it’s difficult to get a video of it.

The issue requires several conditions to occur, but when it does, it’s really weird.

Take this example video that I’ve attached in this post. I used the angled shelling attack to attack a jumping Paolumu from its left. As it jumps up and down and my gunlance is planting the wyrmstake, the wyrmstake ends up attaching itself to Paolumu’s right wing and breaking it.

Since I am attacking from the left, I would expect that the wyrmstake attach itself to either the left wing or to the left side of the body instead of to the right wing.

Please review.

Addendum: Another monster that I often encounter this issue with is the Great Jagras, especially when it’s moving around or doing the barrel roll.

I’m not sure how the wyrmstake cannon worked on other MH titles, but it seems weird to me that when the wyrmstake cannon is fired, the wyrmstake is not actually attached to the monster at that point. The wyrmstake ammo is only truly “launched” when the avatar pulls the gunlance away from the monster, which leaves a spinning wyrmstake in the air which would attach itself to any part of the monster should it touches the monster before it touches the ground and explodes harmlessly.

This leaves a long lead time between activating the wyrmstake cannon attack to the time of the wyrmstake attaching to the monster, and the monster could easily move out of position during this long interval.

Hi,

I would like to add two more occurrences that so far I have encountered the most times:
1. Great Jagras
While standing on its front-right close to its right foreleg, use Burst Fire to break its stomach, then continue the combo by swiping up for Wide Slash and then tap for Wyrmstake while aiming at the head. I am clear from the rest of the Great Jagras’ body, and I am well within range of its head, but the wyrmstake ends up attaching itself to its right foreleg, which was nowhere near touching range of the wyrmstake.
2. Radobaan
Similar to Great Jagras, when I use wyrmstake on its head while standing directly to the right side of its head, the wyrmstake attached itself to its right foreleg instead, which was close to the edge of my screen and nowhere near touching range of the wyrmstake.

I’ll try to capture videos of these occurrences when I can.

Addendum 2024-07-18: As I try to repeat the same kind of positioning and angle of attack on other monsters as what I’ve used against Radobaan, I can reproduce the issue of “aim the head, hit the head, but wyrmstake ammo attach to the forelegs” more frequently. For example, I tried the same move against the Barroth twice, and twice the wyrmstake attached itself to its right foreleg despite the gunlance was clearly thrusting into the middle of Barroth’s head at a right angle from the immediate right of its head and the forelegs were nowhere near the point of impact.

Here is a video of the wyrmstake attaching itself to a Pukei-Pukei’s Right Wing even though I was aiming for its head:

I just had the most bizzare occurrence: I stood in front of a Great Girros and slightly to its right to wyrmstake its right foreleg, but the wyrmstake attached to its tail instead and cut it in the process.

I’ll add video when I can.

Thank you for your patience.

We’ve reviewed this case with our development team and confirmed that wyrmstake cannon may damage farther body part if the hunter is too close to the monster.

Although this is intended, we have also shared your report with the team as a feedback.

If there is any update we can share on this, we’ll do so on this Forum!
Thank you for your report.

Hi @NianticModKKI,

Thank you for the reply! I see. I now understand that this is as designed.

Yes, please do let the development team understand that this is making the wyrmstake attack unreliable at best because we cannot rely on it to stake the correct places. I’m not sure how it works for Lock On, but it is certainly a hit-or-miss thing when played using gyro, and there shouldn’t be such a disparate difference between the two modes.

At least make it stick to to exactly where the gunlance is touching the monster when we’re close to the monster, not to a body part that’s nowhere near the gunlance’s muzzle.

Please consider. Thank you!

私も度々あります。

クルルヤック戦開幕で竜杭打つと、ソロだとあまりならないですが、グループハントでかつ中央以外の位置からスタートすると、頭ロックオンしても発射した杭がポトリと地面に落ちます。

めちゃくちゃ虚しい気分になります。

挙動がおかしすぎなんですよね。それ刺さるの?となるときもあれば、なんでささらんの!って苛つく時も。

もう治ったみたいですけど、チャアクのビンが変な所で爆発するのともしかしたら同じ系統のバグではないかと思っています

Interestingly, it was not considered an issue when I reported it previous, albeit it was in gyro (I didn’t test with Lock On): Gunlance's wyrmstake cannon attack often sticks to other body parts than the spot that's being hit

Hopefully the fix will work for gyro as well, because no matter how I observe, I can only tell that the weapon design for the wyrmstake cannon simply isn’t good enough to be used as a precise attack, despite it being a very precise weapon in the main Monster Hunter games.
