As someone who has played a lot of assassin in D&D, let me tell you this: poison sucks. It takes a long time to make, the materials to make it are difficult to acquire, and if you don't feel like you're making it yourself then it's very, VERY expensive to buy. Not only that, but unless it's a particularly valuable poison, it almost always deals too little damage or is too easy to save against to ever be useful. I've wanted to come up with a remedy for this problem for a long time, so when the artificer class was officially released at long last, I took the opportunity to design this subclass: the poison master.
I spent a long time getting this subclass into a shape I was happy with. It may seem very lengthy (and that's because it is), but to get across what I was envisioning, I had to fit in a lot of rules and options. I wanted to allow the player to not only make their own poisons, but to also make those poisons do exactly what they wanted them to. Do you want a poison that you can deliver through the blade of a sword or tip of an arrow, or that you can feed to an unexpecting victim at a dinner party? Do you want a poison that will leave your victims blind or unconscious, or that will linger in their system and weaken them? Do you want a poison that will leave no trace on a successful save, or a poison that will even work against demons and liches? This subclass allows you to create poisons that do all of this and more. Since magic is also a big part of the artificer's toolkit, it also gives you more spells and lets you tinker around with them to make them especially toxic.
In other news, I've finally found a job, and starting in April I'll be working again for the first time since the pandemic began. I'm excited to start, but I have no doubt this job will leave me with less free time, so I hope you guys understand if it impacts the rate I'm able to pump out content for you.
As always, if you want to get your grubby hands on the high quality PDF version of this subclass, make sure and head over to my dropbox where you can find this and all my other stuff, including another patron-exclusive artificer subclass: the Transforming Knight.
