Terrain Defence As Damage Reduction?

[averyimaginativename]

I apologise if this has been asked before - I have searched, but there's so many RNG complaints show up in the results, I might have missed something...

I'm working on my first campaign, and for a special weapon in a single scenario, I want to change the behaviour of terrain defence, but I can't work out how to do it.

Is it possible using WML to change the chance to hit to 100%, and also to reduce the damage taken by the defence percentage of the terrain they're on?

For example, an attack dealing 10 damage is guaranteed to hit, but when used on an elf on a forest tile would only do 3 damage.

(If it's too complicated for somebody to tell me exactly how to do it, a yes/no answer would be fine - I'm happy to work it out for myself as long as I know it's possible).

Thank you.

The terrain defense on each unit is based on his/her move-type that is on "core/unit.cfg" (in the defense tag) AFAIK.

Is it possible using WML to change the chance to hit to 100%

Yes, it is. (well, I haven't tried it though.)
Refer WEAPON_SPECIAL_MARKSMAN or MAGICAL on "core / macros / abilities.cfg".

and also to reduce the damage taken by the defence percentage of the terrain they're on?

Still yes, but how to do depends on how you would like to do.

Hopefully, these are going to help you.

Here's such a system made into a multiplayer era, you can copy over the events from that. You might need to change them a little bit to prevent the same unit from receiving the modification several times (once per scenario), or to make sure that recalled units get it too.

The code is a couple years old but I think it'll still work.

Spoiler:

I'm heading in the right direction now - thanks a lot, you've saved me from lots of headaches.
