The majority of these are rules I've heard others say need to be looked at. The change I'd personally like to see most is the Non-Plot Roles in the attached document. Some of them we technically already do, I'd like them to be added to the book or at least in their own publicly-accessible document. And of course feel free to suggest any additional roles that I don't have listed.

Food Harvesting: There’s currently no specification on what sources Forester and Hunter can gather food from. The original idea was to make Forester only able to harvest food from plants and Hunter only harvest from animals, but Oceanology makes that slightly awkward.
   Solution Ideas: Go with the original plan of plants for Forester and animals for Hunter, with the explanation for Oceanology that there are edible plants in the ocean such as kelp or they can harvest plants that grow on the seashore.
Alternatively, we could leave off any limit as to what these two trade skills can harvest food from, mainly because while Forester has much to do with plants it also has skills involving animals too (though for Hunter harvesting plants wouldn’t make much sense, unless we make it be similar to the harvest of "special Components" which by the book can be done by Forester and Herbalist).

Spirit Form/Water Form: As it reads right now, someone in Spirit Form can only be affected by a Dispel or Suppression. Exorcise does state in its description that it can remove a Spirit Form, but there’s no mention of this in Spirit Form’s own description. Water Form is worded similarly, with Evaporate seeming to be the only spell that can affect it. Gaseous Form actually lists what spells can affect it in its description, while Stone Skin is vulnerable to all spells.
   Solution Ideas: All form spells could be given only a specific set of spells and/or paths which affect them, as is already the case with Gaseous Form. Doing this would not only nerf Spirit Form and Water Form, but at the same time give a small buff to Stone Skin.
Regardless of what solution we choose, Exorcism definitely needs to be mentioned in Spirit Form’s description (so long as we do keep it as a way to break a Spirit Form).

Battle Rage & Blood Rage: Either specify that they can be used from -1 body or ensure it is run by the book where they must be conscious to use them.

Foci Arrows/Bow: There’s nothing saying whether to cast spells through a bow requires the bow or the arrows to have foci on them. I believe it’s been run as the arrows in the past.

Rewrites: During a pre-reg we agreed on the following temporary changes:
1. You do not keep your character deaths if you rewrite into a completely different character (changing their name, race, class, etc).
2. You do keep your character deaths if you rewrite as the same character with changed stats.
3. A rewrite can be used after a resurrection pick is failed to retain full character points, but unlike when a rewrite is used normally the possessions of the previous character must be handed over to plot.
(I’m primarily bringing this up in case we want to change it any, or simply add it to the book to make it official.)

Breaking Down Equipment: I remember us discovering during one of the games that apparently we have no written rules for breaking down equipment into components.
   Solution Ideas: (Heath:) There was an errata idea that I wrote up but did not propose adding a function to Weapon Smith and Armor Smith that allowed equipment to be broken down and return 75% of the materials used to compose the item.  The other craftsman skills wouldn’t be able to be broken down into its component parts again.  You could allow Hunters, Miners, and Woodworkers to recover hides, ores, and woods from armor and weapons and Jewelers to recover ore from jewelry (this could alternatively be done by an Armor Smith).
   (Jon:) I believe that it should be a Smith skill only. Simply because the Tradesman skills thematically are for collecting raw resources not reclaiming refined resources.
Jewelers though makes sense that they could reclaim gems/75% of the cost to make.

I think it wouldn't be worth the trouble to try and split food harvesting. While it may not make a ton of sense, the type of food you eat has no impact on the benefits you receive, and the sticks simply say "Food". Adding more complexity to this doesn't seem to me like it would add any worthwhile benefit

I really don't see any reason to not allow the bow to be focused.  Requiring archers to have focus arrows just makes it harder to be an archer, which we should be trying to avoid.

But mechanically, you're basically channeling a magical effect into the arrow through the bow's focus and then releasing the arrow and its effect onto your target.
