Cursewright leaves Early Access
That was a Potion of Healing stack, but one of those in the stack was poisoned. Common rarity, the right red flask, the right wording on the sheet, regains 2d4+2. Aoth drank it mid-fight, already bleeding, expecting the obvious. It was poison.
That is a Deceptive Consumable, one of Cursewright's curse archetypes. The item presents as the genuine article, down to the description and the Drink action and Stacking behavior. The healing never fires. What fires is a Constitution save and a lungful of venom + the Poisoned condition for the next hour. The table sees a healing potion right up until the moment it doesn't.
Cursewright is the curse engine for D&D 5e on Foundry. It comes in three parts.
The engine. Curses escalate over phases and intervene in play, with GM gates so nothing fires until you want it to.
The library. Handcrafted cursed items built on four behaviour archetypes: Slow-Burn Equipment that stays useful until the trap loads, Deceptive Consumables like the one above, Combat Triggers that escalate as the fight goes on, and Devouring Containers that are less "bag of holding" and more "predator wearing the shape of useful gear."
The Curse Author. Build your own from any of those four templates (more in time).
This release takes Cursewright out of Early Access. The engine is stable, the item library covers the SRD cursed-item catalogue, the Curse Author is open for homebrew, and it is verified on Foundry v14. It runs on the dnd5e system.
How to get it:
1. Subscribe to the Acolyte tier or higher here on Patreon.
2. In Foundry, install the free Ionrift Library module if you don't have it.
3. Open the Ionrift panel, sign in, and link your Patreon account.
4. Cursewright shows up as an available premium module. Install it like any other and enable it in your world.
It is a premium module delivered through Patreon, not the Foundry package browser, so the panel is the way in. If anything in that flow trips you up, say so in the comments or the Discord and I'll help out.
