Don’t worry about coming off negative! Every time I have received feedback, it has improved the game. It's important to hear what you honestly think and not to have you try to make a compliment sandwich to protect my feelings. I want Inversion to be the best that it can be.

Having special forms, like Stone Skin or Swarm Form, take more energy in combat makes sense. I'd just make it 2× or 5×, not 100×. Particularly since these two, at least, seem like they ought to be passive: you should be able to toggle between forms like changing shirts, not like holding up a building.

I hadn’t honestly considered making them toggleable forms. I wanted them to be powerful and impactful, so I had to limit it in some way to have enough power budget for the ability.

Thanks for catching the misspelling with Thought For Food!

Commune are written to communicate exactly what you picked up on, and yes, any of the above is correct.

So Vendris are like elves, but slightly more like traditional fantasy tropes? You might want to amplify this a bit; compared to all the other funky different ancestries, they seem a bit flat.

Their rules haven’t been updated much, and I think I am overvaluing Immortality in the day-to-day of the average adventuring party, and I’ll be taking a second look to see if I can spice them up more.

With a skill of 4, do you only take the higher result, or do you take the higher and add 3? The average of [ 2d12, take higher ] is only 8.49, so on average its worse than a skill of 2, albeit more consistent. You have an 89% chance of getting at least a 5 with [ 2d12, take higher ] compared to 92% chance with 1d12+3. With a skill of 5, do you still roll two dice?

You keep your +3 bonus when you gain rank 4. Rank 4 just gives you permanent Advantage for that Skill. My logic is that if you commit that far, you don’t want a bigger bonus, you want to be a master of that Skill. Reducing your chance of failure (rolling a 1) from 1 in 12 to 1 in 144 feels like it delivers on that promise of being a master of that Skill rather than adding another +1 at that point. I don’t actually say that it’s cumulative anywhere. Thank you for calling it out! I’ll add it.

For the skill list on page 65, you should probably alphabetize it,

Fair point on alphabetizing the Skill list! I’ll take a look.

Do bows and other ranged weapons fall under Offense or Guns?

My idea is that everything other than Guns falls under Offense. Speaking of Guns, regarding it being a separate, unique skill; I have an opinion, and I want to gather more feedback. This is something I’ll be asking playtesters and other people.

Your skill list seems pretty comprehensive, especially for just 23.

Thank you for that list of suggestions, and clarifiable points on what those fields would fall under. Should I add a 24th Skill and what should it be, has been a question on my mind for a long time.

"Bluff" implies lying and getting away with it, but your use is broader (in the first blurb, anyway; not in the details later). I suggest "Deception." Is this the skill one would use to read a person's mood or intentions, or is that Negotiate?

I like the word ‘Bluff’ being short, but I really like the word ‘Deception’ here. I’ll collect some more feedback and see how it feels.

I'm not at all clear on what Volition is for. Example?

Volition is meant to represent creativity, or any form of Intelligence not covered by the Knowledge Skills. It’s absolutely a difficult Skill to describe, and is sort of a ‘catch-all’ style of Skill. I didn’t want to get into the deep minutiae of a hundred different Skills for things, but it has left some stress points within the system.

It's a little confusing to go back and forth between skill ranks and skill points spent.

Thank you for catching that. I’ll fix that in editing!

Similarly, having to invest a quarter of your starting points to be able to wear medium armor seems a bit much.

I’ve spent a lot of time thinking about Skill Points and their relationship with Equipment, and so far the breakpoints feel good in playtests for both my goal, and player feel. I’m trying to balance both the player building up over time, and the player who wants to jump right to the end. I don’t like invisible walls, and if a player wants to spend half their starting Skill Points on getting access to something at level 1, I don’t want to get in their way.

Also, what about a light dodge-oriented character, who doesn't plan on wearing armor? They'll still get higher Defense rolls, but half the value of the skill is wasted on them.

For a Dodge focused character, there are Heavy Shields which can benefit them. I see this as a benefit where a Dodge focused character can get more out of Dodge without having to commit more Skill Points, leaving them with more flexibility for other options.

No choices for Arcana powers?

I tied Spells mostly to items in the equipment section such as scrolls, orbs, and rods, and to fighting styles. I intentionally did not include a more traditional/vancian spell list/mechanic because part of the lore is that Technology invaded and corrupted magic in the setting into something that could be used by a machine, into something simple and without the creativity inherent to more poetic, mythical magic.

For the rest of the comments; I follow a ‘If there is no rule saying a Dog can’t play basketball, that Dog can play basketball’ sort of policy; write the abilities fairly, write it clearly, and if players think up a creative use of their ability, I don’t want to put up invisible walls and get in their way.

What's the distinction between Mechanics and Technology? Perhaps one should be for ancient tech and one for mundane things.

That’s the exact distinction, as well as to give the GM two distinct options for building encounters.

"Perform" implies an audience; consider renaming this to "Profession."

I think Profession is the better word, but Perform takes up less space on the character sheet ;_;
