These are automatable now, so we should actually mothball the effects and probably move the automation to the feature itself.

That sounds like a good idea. I'm just not clear on some of the details:

1. The terrain type should probably be a drop-down, because of things like Terrain Master being able to change it short-term, right? And a choice set would require removing and re-adding the feature.
2. How would we detect whether the actor is in that terrain? Just with toggle or anything more elaborate like regions?
3. Is ignoring difficult terrain from regions possibility?
4. I'm not sure how I would go about any part of this tbh: Arctic: You need to eat and drink only one-tenth as much as usual, you aren’t affected by severe or extreme cold, and you can walk across ice and snow at full Speed without needing to Balance.

Sorry, been away from merging for a bit.

1: We can do a drop down with terrain master to do the swap out, but we shouldn't make the initial choice a toggle like that. Basically a choice set and a separate roll option to set the terrain, predicate the roll option on not having terrain master. Then terrain master can have suboptions.

2: It would be with regions. terrain:x as the roll option already works.

3: Not currently. We need to figure out how we are going to handle difficult terrain in the system itself, which is waiting for some stuff in v13.

4: We wouldn't automate any of that

Thanks for the clarifications!

I'm on it, but running into an issue. I have to predicate the speeds on whether the actor already has the relevant speed type or not. So for example ["speed:swim"] applied to a FlatModifier or a BaseSpeed respectively, but that doesn't seem to work. Here's the most simplified version of one such RE:

{
  "key": "FlatModifier",
  "selector": "swim-speed",
  "type": "status",
  "value": 10,
  "predicate": [
    "speed:swim"
  ]
}

Applied to an actor with a swim speed I set to 5 beforehand. And it just doesn't take effect. Nothing on the log either. Any idea what I'm missing here? How would I investigate this further? I'm not sure how I would "debug" this.
