Increase damage and armor penetration of 84x246mm and RPG-7 ammo.

[LucioFurnari]

Summary

Summary: (balance) "Increase the damage and armor penetration of 84x246mm and RPG-7 ammo."

Purpose of change

The base damage and armor penetration are to low.

• fixes 84mm HEDP rounds have incorrect stats, do not work as intended.  #2380

Describe the solution

Increasing the amount of damage and armor penetration to fulfill the intentions of the ammunition, i use for reference this page of wikipedia: https://en.wikipedia.org/wiki/RPG-7.

[Lamandus]

did you do some testing? We have some other exposion code than dda, so it would make sense to try against APCs, buildings and groups.

[LucioFurnari]

Now that I tried against APC, I can't penetrate the entire vehicle, I increased the damage and armor penetration again, but it's not enough to destroy it.
Any suggestion to improved ?

I can't penetrate the entire vehicle

I think there is room to compromise between reality and current game mechanics limitation. Maybe it does not have to penetrate entire vehicle. if it works well against monsters - maybe it is enough?
I mean player using launcher against monsters should be most common case anyway.

[LucioFurnari]

Well i tested against kevlar hulk and skeletal juggernaut destroyed them one shot, i can change the values if you guys think is so much, I think that an rpg-7 should be enough to destroy any zombie with one shot.

[chaosvolt]

I agree that the threshold for anti-tank weapons should probably be "reliably lethal to hulk-tier enemies" yeah, I suppose see how low the values have to be to accomplish that?

[LucioFurnari]

For a example with a rpg-7vr ammo i can kill a kevlar hulk with one shot of 1500 damage.

maybe we could keep using EXPLOSIVE_HUGE, rationale:

1. only 20% of shaped charge's metal jet is concentrated to target, the other 80% is radiated like normal explosive.
2. RPG-7's lethal radius is 7+ metres.

json lint fails because it's incorrectly formatted, please refer to JSON_STYLE on how to use the json formatter.

I think it would be better to buff overall explosion damage to x2 ~ 3, instead of just heavily buffing the bullets themselves. so bullets could have around 100~300 damages, while bulk of damage is done from explosion.

[LucioFurnari]

Thanks for the corrections and suggestions. Maybe i can change the damage of the explosion effect and see the result damage.

Is keeping the armor_multiplier but increasing it to 2x intended? It'd basically increase the effectiveness of any armor left over after taking armor_penetration into account.

[LucioFurnari]

I just leave for test, is not intended sorry for that, personally i dont know if this request is good or not, if is this balance for the game, after testing, now do more damage, but not to much to be broken.
I testing increasing the damage of the explosion, but the damage destroy z level tiles.
With the actual damage at least kevlar hulk recieve damage, but are not insta killed

[chaosvolt]

No worries. I looked at it and things look better to me, it's a distinct improvement to items that're meant to be effective against huge monsters without reaching Tankmod Revived levels, so.

[chaosvolt]

I'm hoping this wasn't a mistake to merge, the numbers look okay to me given these are non-renewable items but I should've taken a closer look at the related issue as well.

[chaosvolt]

Gave this some further testing to double-check the results indicated in the PR (I should've done that before merging, I was kinda half-awake) and the buff really isn't that big. Tested all RPG-7 and 84mm rounds against a full-health kevlar hulk each time Of them, the tandem RPG-7 round was the only one I could get to one-shot a kevlar hulk, and only with a critical hit. The thermobaric rocket was also basically certain death despite its base damage being a joke, but that's just because fire is the biggest monster of all.

Thing is, most of the 40mm shells are a good bit beefier than these, while these are more rare and precious than grenade launcher rounds. Of these, only the Mk 19 can one-shot with a crit, so I don't think they need a nerf that badly. So it'd probably be reasonable to make most of these rounds a bit more consistent and lean towards that general tier of "can one-shot a kevlar hulk, but only with a crit" but would have to see I guess.

Also of note: the 152mm TOW rockets are also irreplaceable consumables, can only be used mounted, have rather bulky ammo, have only one shot, and leave you vulnerable for a good while if you don't do the job. These are probably the only weapons in vanilla that can probably get away with being strong enough to kill a kevlar hulk on a standard-tier hit.
