## About The Pull Request

Partially reverts a change i made to Rust walkers summoning ritual by having it require Iron(slightly more than it once did) instead of titanium.

## Why It's Good For The Game

Couple of months ago i made rust walkers more expensive to summon as the result of how punishing the vomiting chain stun was and how rust walkers allowed you to rust the station a lot quicker that you normally would.

That was the wrong way to tackle the problem though, As from what i've seen  barely anybody bothers summons these guys after i changed the recipe, and it was probably the disgust itself that needed to be nerfed, which it did.

The vomit is now a knockdown instead of a hard stun and cannot be costantly chain proc thanks to this PR.

tgstation#85944

We do want Heretics to use summons, it brings other players into the fun and makes the round chaotic in a fun way.

That's why i'm partially reverting the nerf, it still requires more iron than it once did, 10 sheets instead of 5.

Admittedly titanium as a reagent was a bit stupid considering it cannot even rust IRL, oh well....
