LORD ORBIUS VALANTHRU IS DEAD
Two campaigns spanning 5 years this beholder turned overmind has harried my players, but last night the Hard Earners said no more.
With spell and blade in hand, they took on the beholder and vanquished it in its underground lair of Oblivion.

One thing I think Pathfinder 2 did really well was the idea of the magic spheres
Life, material, Spirit, and mind. Making each major magic class a combo.
Bards: spirit and mind
Druid: material and life
Cleric: life and spirit
Wizard: mind and material
If nothing else, it gave Druids fireball.

I just discovered a product I bought was a pdf and not a physical copy and I thought it was a physical copy. I get it. Things are changing. But man I don’t like PDFs. Give me a book I can destroy with my grubby little hands

If this is a program for you, go to your settings on your account and there's an option to hide all products that use "AI".
It's not perfect as a lot of creators break ToS by refusing to disclose use of algorithmic generation, but it cuts it WAY back.

It’s drowning in AI submissions
And they stopped updating older out of print books for print on demand.
I know there’s cool new stuff coming out too but hot damn, I’m getting tired of having to sift through slop.

Gary Gygax did not invent Chainmail, despite some discussions in the ttrpg community.
He also did not invent brigandine, plate, cuirasses, ring, or lamellar.
He might have invented laser armor (a series of laser swords tied together to create an armor you don’t want to move in)

In retrospect I should have just said Drivethru.
DMsGuild is the “spoke” of that hub I am on most often, but the problem extends to Drivethru and pathfinder infinite as well.
I’m not sure about the others as I never go to them.

Abandoned as an orphan with a pack of grognards, I was raised in the wilds on the teet of polyhedral dice.
It wasn’t until I found love in the form of a British woman that I was able to bring what I had learned back to civilization.

Pro ai people telling you it’s “an inevitability” are selling an idea to you.
They need you to accept it as a non choice, because that’s how they normalize removing more of the human aspect from the equation.
You can say no.
I say no, verbally and w my wallet.
