So we had a large landing platform that the owner wanted to make usuable for TAGs to vault up onto. Currently it's taller than S7 so he printed a loading lift with the intent of making it a platform for them to use to vault onto the main pad with as pictured below. The thing is the lift is smaller than an S7 base. I'm pretty sure multi vaulting during a move in N3 was illegal if you couldn't get a spot to fit the base each vault, otherwise you needed the rules for stairs essentially. Is that still the case in N4 though. There's an image on page 37 where a model is double vaulting two obstacles, but it's vaulting over obstacles that are shorter than it rather than needing the vault to scale an obstacle that is larger.
There’s two examples of vaulting on page 37, an example of allowed vaulting and an example of prohibited vaulting. But concerning whether you can move across things where your base doesn’t fit, turn back a page. You’re not allowed to stop somewhere your base doesn’t fit (or is not supported), but you can go through those areas during a movement.
Alright so that lift should function as the owner intended then to let TAGs get up onto the landing pad
Yeah, it should. You just have to be willing to put up with the idea that if a TAG is short on movement, they have to stand next to the lift instead of stopping on it. :)
Gonna have to look in the book, but I'm fairly sure that vaulting doesn't work as Solkan expects it; max height gained across the movement is compared to the last position where your bas was fully supported. You're gonna have to define that as a ramp/stair for large silhouettes prior to the game and you'll be fine. Edit: yeah, a TAG won't be able to vault that - you may at no point have a height difference greater than one silhouette to any position is probably the best way to describe it. Though if you move the ladder next to the platform a bit closer to the lift so that it's not at an angle then a TAG will be able to use that ladder by placing the base on the ladder and on the rebar on the side of the lift for sufficient support.
This.. Vault movement can't be used to get higher vault movement. What you've got is functionally better described as stairs. It was a weird Discovery for me to realise tags can now use ladders which are atleast half their base width!
You appear to be making up rules concerning the part in red. The height of the obstacle, on each side, has no specification for the trooper whether its base is fully supported or not. The height of the obstacle doesn't change for an S2 or an S7 trooper. Likewise, the movement rules place no requirement on being able to stop on either or both sides of the obstacle to vault it.
Suggestion for this specific piece of terrain: Play it as a ramp, same as regular stairs would be. Allows the TAG to stand on the lift by treating it as a diagonal surface despite physically being unable to fit the entire S7 base.
Yeah it's not really explicit. I'd take it that you need to have your base fully supported between vaults but the move skill only requires you to have your base fully supported at the end. I suppose if it meets the half base width requirement it's a tick.
As far as I can tell, there's nothing stopping you from simply saying that it counts as stairs for anything larger than SX (X = your choice). As long as that's spelled out before the game to everyone that plays on the terrain, it should be fine.
AFAIK vaulting addresses the part of the Movement rules that say "The Trooper’s base must always be in contact with the surface on which they intend to move," alongside the stairs rule, by giving you a way to traverse areas that are different heights and bypass obstacles that don't permit the model's base to be "in contact with the surface." The first example diagram in the right column of p. 37 makes it pretty clear that you're not obliged to end at the same elevation as you began when vaulting. There's nothing specifying how many vaults you can execute per Move, just restrictions for each vault. There's a vertical restriction that "obstacles" where you can't be "in contact with the surface" fully have to involve a vertical traverse no taller than the Silhouette height, as shown in the second example diagram in that column. (Third bullet of General Movement Rules, p. 36.) There's a horizontal restriction that the path of movement can't be narrower than half the base width (second requirement bullet of Move skill, p. 35)...as shown, that width is measured perpendicular to the path of movement. There's an endpoint restriction that you must be able to reach a final position where the base is fully supported (third requirement bullet of Move skill, p. 35). I think that the way this works in this case is as follows: The TAG can vault up to the lift platform as long as the platform's surface isn't higher than the TAG's Silhouette height. As long as the platform is at least as deep as the TAG's base, and half as wide as the base, it resumes being "in contact with the surface" on the platform and the first vault is completed. The TAG can then move forward if necessary, then vault a second time up to the flight deck level—again assuming that the vertical distance is smaller than the Silhouette height of the TAG. If the TAG can make it from the starting position to the end position where its base is fully supported by the flight deck surface, it doesn't need to clear the whole elevation in a single vault, but that depends entirely on whether some part of the lift platform is large enough and open enough to count as clear space for legal horizontal movement between vaults. (The minimum clearance here is a rectangle 27.5 mm wide and 55 mm long, placed parallel to the direction of movement. If the platform is less than 55 mm deep, the TAG might still be able to manage it by moving diagonally if it has enough MOV to make it up in a single Short Skill.) I usually think of this as the "Everybody Knows Parkour" Rule. The distinction between this and stairs is that the stairs don't all have to be deep enough to support the full length of the base, which would be required to be able to series-vault up them. Because stairs are diagonal surfaces, you can stop halfway up (as long as they're base width or wider) without being out of contact with a movement surface, so even if an individual stair is too small to support the whole base, you can end movement on stairs legally.
That's an interpretation of the rules you highlighted in red. Arguably, the obstacle never stops until you are able to plant your feet on the ground firmly. However, in this case you have the second situation in the rules, I'd say quite clearly but here we are. You're trying to navigate two obstacles; the elevator and the platform. The platform is an obstacle you can't traverse up to because it's too tall. As you can see in the second example, the rules states that "the obstacle is too tall" even though the obstacle item itself is not too tall but instead the rules treats both the piece of terrain and the lowered floor as a single obstacle. Equally in the first example you have the floor dip (road curb?) and two scenery items both treated as a single obstacle. Edit: And you also need to answer when you stop vaulting over the first obstacle if you want to treat them as individual obstacles. Keep in mind that if you can't identify a good coherent way of doing it, I can give you some pretty convincing exploits for getting Climb+ with infinite vertical movement on basically any miniature.
