I wasn't going to do this just yet, but hey...SURPRISE! It's an archetype from my own home-grown campaign setting for you to peruse and swipe if you like. My world has a lot of complicated old gods, and this particular thief archetype is an exploitation of that very fact. Click the link below to get it.
Thief Archetype: The Divine Archaeologist
This is a spell-casting thief, with an emphasis on utility spells, such as hiding, running, and transporting heavy objects. That's why the Divine Archaeologist also gets a second fourth level spell, and a fifth first level spell at Level 20, unlike the Arcane Trickster.
There is also an "Indiana Jones" component to the Divine Archaeologist; the clever fellow who has read up on the temples of the blood god and knows that every treasure room has a pressure plate right...there...or, maybe it was there...? I wanted the skills to reflect someone who learned a lot about ancient history, but little else. The notebook seemed like a good way to reflect that, with the added incentive of it being potentially stolen the night before a major temple raid.
My intention is to talk more about my campaign and the stuff I've done to 5th edition to accommodate my brilliant ideas and grandiose vision.
And Just for Grins, here's all of the other tidbits of homebrew and campaign stuff I've shared since the beginning of this 31 day challenge, in case you missed anything.
