Combat is not still, depending on the rest of combat, someone may move into your line of fire.
But it does in general take a lot of actions to set up a fire-from-hidden situation.
Or get a wizard to upcast invisibility to let you stay invisible while sniping. :)
Not breaking at all. Heck, alchemists get to use crafting, and a class feat can be used to make Nature the skill check. You should probably look at Herbalist archetype for wording.
From a GMs perspective, there are occasionally mobs who are trying to hit above their level, and have nothing better to do than go all out on their attacks. I usually have them switch to their agile attack for their second and third attack, because they are trying hard just to hit.
Ropers are very good at denying movement. For the right party, even just one roper can be a challenge.
It seems like a good idea to me.
I completely ignore the activation action for magic ammunition. You are already spending an action to fire it, and burning money before finding out if it hits, and then there is usually a save after that.
Another Foundry + A/V on discord.
I also use discord for game related threads.
I've recently discovered a similar program called Guilded, which seems to have all the same important creatures of discord, but better organized (and a larger file share limit). We have not moved over, but I've been spinning up and organizing a server there, just in case Discord craps the bed like Reddit did.
I use ABP so that we can skip the less interesting +X stuff.
One of my players is very into crafting, and they work as a group to be able to afford things, so one of the best treasures I can give are uncommon or rare items, or even just the formulas.
I tend to focus more on fun than utility items, though this varies. And I like to give out thematic stuff. Recently they fought a Skuln, which is described as having adamant claws and teeth. But it has no listed treasure, so I gave them adamantium chunks as treasure from scavenging the body.
