The Artificer
Keeper of Systems
"I watch the game unfold. Then I build something worth fighting for."
A goblin ambush at a foggy crossroads. Two PCs, one monster, initiative rolled. The Artificer runs the fight. Round one: goblin wins initiative, hits Lyra for 5. Round two: Firebolt, the goblin drops. Victory in two rounds. Lyra barely singed.
Too easy. The Artificer knows.
So it adds a second goblin to the stage. Runs it again. Now round one is dicier -- Lyra takes 9 damage, Theron nearly drops in round three. Better. The Artificer writes both scrolls and tells you what changed.
That's the work: observe, adjust, iterate. Not just reporting what happened but closing the loop -- tuning the stage until the numbers tell a story worth playing. And because it's watched a hundred fights across a hundred stages, it knows what a party at this level can handle, which means it can design the magic item that challenges without breaking them, or the house rule that smooths the edge case that came up twice last month.
The Artificer doesn't guess. It has receipts.
