Looks like a phrasing mistake on our end. It shouldn’t specify melee-only; the attack penalties apply to ranged attacks as well.

No action, but like Power Attack, you choose to take it before you attack and it persists to the next turn (you can flip it on/off at will).

Glad you got the replacement and that you’re enjoying the rules!

Hi! I’ve pinged you via email so we can sort things out.

Congrats on the release! I love the spoopy vibes!

We decided that for the print book, we would limit ourselves to the Core Rulebook. This was mainly to manage the scope of the document (Pathfinder has a lot of rules!).

I think if you look through the comments here, and through the website comments, you’ll find some homebrew solutions people have whipped up.

Hi! We’re from Canada, but I think that should work out. I’ll send you some extra goodies if the shipping cost ends up being lower than you think too.


Thanks! We definitely had a lot of fun putting this one together.

Thanks! Can’t beat non-repro blue and silly doodles.

I’m not overly familiar with those rules, but I suggest that requiring the Modified Weapon Proficiency feat would make sense. It seems designed to mesh Weapon Modification with class features.

However, the Rapier is not particularly game-breaking (it’s essentially the same as a Wave Blade, from the same sourcebook) so I might just let them use one anyways.

Thanks! I do wonder if I need to make a “printable” version of this though, so folks don’t use up all their black ink before they get to make a zine.

Hah, thanks! We wanted to make something that was fun but also a bit psychically damaging.

Thank you! We had a troubling amount of rhymes in our pitch document for this jam.

Hello! The Elephant in the Room uses only the Core Rulebook feats (for the most part) and Furious Focus was released in the Advanced Player’s Guide.

My suggestion would be to introduce it as a standalone feat with a STR 13 and BAB +1 prerequisite.

Hello there, and I’m sorry that your hatred for the PDF burns so brightly!

We’ve generally found that folks are split down the middle between preferring the original blog post and the PDF. One of the reasons we made the PDF was to respond to the 100+ comments we received on the initial post, in which people asked for rules clarifications and more detailed advice on how EitR interacted with numerous feats. We added some additional homebrew flourishes to flesh things out further but, like all aspects of the rule-set, they are completely optional.

Regardless, to say that we do this type of design work for profit is a bit humorous to me. While we are certainly grateful to all the folks who have chosen to pay for a copy of EitR, the profits we make off the publication are relatively meager (and certainly don’t cover the labour we put into it). In fact, any of our funds go straight into a stash that we have dedicated to future TTRPG development. This is strictly a hobbyist endeavor, which is why everything Mammoth Island has made thus far is essentially PWYC.

After 13k+ downloads, and with Pathfinder 1E all but wrapped up, I don’t see us revisiting or revising this rule-set in the future. You’ll have to enjoy it as-is or move on. If you are looking for another source of Pathfinder homebrew content, I’d highly recommend Spheres of Power.

Take care!

This is a tough one!

I agree that Spell Focus can be pretty useless for some spell schools, but making it universal might be a little OP (that’s a flat +1 to DCs, essentially). If I were to homebrew something, I’d probably have Spell Focus grant some sort of minor boon in addition to the DC boost. Think along the lines of Varisian Tattoo and how it grants minor spell-like abilities:

I can’t open the PDF at the moment, but I’m assuming it reads as arcane-only because: a) that is how it is in the original book, or b) it’s a typo. I’d default to whatever the Core Rulebook says as we didn’t intend to change anything with Spell Focus.

Hope this is useful!

Hi Steelhaven!

Not sure what you mean by credit, but we always appreciate it when folks share the rules with others. Just linking to this page means a lot to us! If your players want to chip in a couple bucks to help our self-caffeination efforts, they can do also do so through the PWYC purchase options.


Hello Rizzoxiii!

We wanted to give both Deft Maneuvers and Powerful Maneuvers a movement impeding option. The actual implementation is a bit of a mix of Stand Still and Scorpion Style, and the name is really more of a metaphorical adoption of hamstring (impeding movement or limiting activity) rather than a literal attack on someone’s tendons.

Also, Deft Maneuvers also improves a character’s ability to feint, so the disparity between Deft/Powerful is not quite that large.

Removed, but not by intent. I think that it fell through the cracks when we made the switch from individual weapons for Weapon Focus to Fighter weapon training groups.

I think I’d probably house-rule that “rays” can be selected for Weapon Focus.

Extra Rogue Talent is definitely a mistake! We’re going to “hot fix” the pdf sometime in the coming weeks with that change.

Dirty Trick is APG, so we didn’t include it in this document (which is, for the most part, Core Rules only). Feel free to include Dirty Tricky for your own campaign - we’re not opposed to having it part of Deft Maneuvers, it’s really just a rules-scoping thing.

One of the things we grappled with when designing this document was if we should present it as:

a) A self-contained rules document, that wouldn’t require consulting back to the Pathfinder Core Rulebook. b) A list of errata/changes that could be skimmed quickly.

We ended up doing a bit of a mix of both these approaches. We listed all the (core) Pathfinder feats so people could build their characters without having to flip back and forth between books. We also added appendices that quickly list the changes, so folks who are already familiar with the rules could take in everything at a glance.

Additionally, we found that even changing a couple of feats created ripple effects throughout the entire feat tree. We had to tweak the prerequisites and wording of a bunch of otherwise unaltered feats to resolve minor rules conflicts, and including the full feat listing helped us keep track of things.

Hope this answers your question!
