Caster Level Checks not being attack rolls, Spell Resistance, Sanctuary, touch attacks and harmless spells
Maybe I'm misunderstanding that slow snare but it seems it does not help in attacking as implied earlier. Something enters the square, the snare goes off and causes difficult terrain for a moment slowing it down briefly, then clears itself leaving normal terrain. Which means you can only get that bonus if you ready an attack (if that is still a thing).
Spell less though is good. Just doesn't really have any cool stand out options for me.
You could have various languages be of different rarity much like how spells will be now. So you could learn any of the common languages easily enough, but the more uncommon or rare languages you'd need to spend downtime/extra points/find a copy of the rare language to be able to speak or read them.
For my own version I am planning on a separate set of systems that are linked by a slightly different frequency of drift beacon, so they could be accessed by pact world drift drives, but their own leans to closer and quicker travel. Not canon, but makes marginally more sense for extra-Pact World empires to work sensibly.
Teleport trap to a demiplane doesn't work.
I'd suggest teleport to a room with a nasty creature inside it. Tough enough that the players struggle, but that they can overcome it. Then if they survive and continue to teleport in, increase the lethality of the destination room (tougher monsters, spell traps, more of everything).
I find d20pfsrd a more useful resource when browsing for interesting character ideas and such. However AoN has a massively better way of listing magic items - d20pfsrd doesn't have a list of all the magic items in price order, just those from the first few rule books which makes it hard to find interesting items of the right cost. It would also be nice for d20pfsrd to have a tick box in the search to remove 3pp listings - some of the paizo stuff gets lost amongst this.
However the linking between pages is a massive bonus and makes it really easy to find out what the monsters spell does, or what that feature does quickly without having 101 page loads trying to find it. Plus the rules there are very handy when you don't have the book/PDF to hand.
In one of the earlier APs, in the last book there is an encounter with some ruffians and a hidden creature that grants wishes working with the ruffians. In it, it explicitly says that the ruffians have to say "I wish..." for the creature to use its ability to grant a wish to his allies.
This seems to indicate that you cannot twist a request or suchlike without I wish being part of it.
I've not seen a guide, but personally I find the ones that add crit effects to be the most useless (unless they also add a secondary damage type). WIth crits now only on a 20, it seems a waste to add something so expensive for little payoff (especially as some of those added crit effects are not that impressive).
The more utilitarian ones, like ignoring concealment/cover or hiding the weapon seem much more useful and worth taking.
The biggest issue will be that they won't necessarily have access to the engineer, captain and scientist options as they will all be pilot/gunner for their individual ships. There is an option in the Pact Worlds books that can link them together to share these rolls, but it might be a bit weird.
As for progress in combat, they might do ok, but with tier ships that low, they may be running very low on BP to get a gun and shields sufficient to avoid being destroyed in just a couple of hits.
Pact Worlds had a ship system that you could buy that allows smaller ships to share certain information between them (can't remember the name at the moment, but from the ABallonian ships). I seem to remember that all ships in the network allowed them to use the same science/captain actions amongst all of them, reducing the penalty for everyone being in smaller ships.
They are on a ship for a while presumably? Why not hit them with a disease? You can make a custom one rather than the existing ones if you want to increase the difficulty of them passing and hand it off as something the assassins cooked up for these sorts of things. Could also switch and use the unchained disease/poison rules to make them a bit nastier.
I had a go a while back at making a classless PF set. I basically took the various abilities the classes get and gave them a feat cost. So smaller ones like Trackless Step were only 1 feat while something like Rage was 3 feats. Spell casting was 2 feats for 3 levels of casting, with you having to pay more to get higher level spellcasting. I never got around to finagling it so ensure that you could build the current classes with it and I am sure there are ways to abuse it, but it was an interesting thing to attempt.
Uh, undead and constructs are not immune to crits etc (well at least in PF1, so I doubt that would change in PF2). Just elementals, oozes and proteans.
I wonder if multiclassing means you just start at the bottom of their abilities(ie level 1 as we do now) and earn the class/general/ancestry feats based off of that new line. ie you do 3 levels of cleric then move to rogue, which may mean your level 4 feat is a class feat rather than a general feat that you would normally have gotten (or however the progression is set). WHich might mean that multiclassing gives you less general feats but more class feats?
I wonder if it is that way or something similar, when you level up as wizard as a wizard/fighter multiclassing, could you use your wizard class feats to buy feats from the fighter group, or if it is hard limited to the class you just leveled up in.
Lady-J, since the half-elf/orc are just a human/elf, human/orc combo, it seems kinda redundant to put them in this. I mean yes you could then get 1/4 elf etc, but at that point, why not go further and do this for all of them and then it gets so much bigger and harder to combine.
Per the primary/secondary, the secondary stats still get the ability scores, languages, etc, its just they are exactly the same so again seemed redundant to put the same information in a second time. I had thought I put a line to that effect in there somewhere where I explained how to put them together.
Sheepish, haven't seen that (although I do have that book). By offer for free on Paizo page, I presume you mean the store there?
