Design Thoughts: Toxic Substances Conversion from d20 System Games
🕑 Added 2020-04-21 22:15:59 +0000 UTCI've been converting 103 toxic substances from Dungeons & Dragons 3.5 and 5th edition, and Pathfinder 1st edition, meaning that this is the time I get to definitely establish the price and damage conversions I'll use from Dungeons & Dragons and Pathfinder to Ironcrunch, at least in terms of items (not foes). The principle is to achieve balance and verisimilitude with the meaning of the numeric values with thins system.
After much fiddling with the stats, this is the most balanced formula I came up with to finish and polish the upcoming hazards, traps, and toxic substances sections of the rulebook.
PRICES
Each 200 gold piece from Dungeons & Dragons and Pathfinder equals 1 wealth in Ironcrunch, rounding down or up depending on my own judgment of balance according to the item in question. Anything that goes from 2000 gold pieces and beyond equals 10 wealth.

- Prompts to make a save throw every turn: Poisoned (severity +3) condition.
- Lasts 1-12 hours: Poisoned (severity +1) condition.
- Lasts 13-23 hours: Poisoned (severity +2) condition.
- Lasts 24 hours or more: Poisoned (severity +3) condition.
- Can't be healed by any means: Poisoned (severity +3) condition.
SOME NOTES AND WHAT'S NEXT
Some poisons have been shown to grant some benefits. For these cases, I chose not to let them listed among the toxic substances, but with the consumable items, leaving the negative effects of each as a drawback for the benefits they give.
I'm currently working on balancing all these substances. Soon, I'll release a Google Drive Excel file with them all so you have a better perspective.

How about stuff above 2000gp requires some sort of additional leverage, eg. A bond, an additional cost (in the same way a weak compel requires one) or even a strong hit on a move. I'm not too familiar with 2000+GP priced items in Dnd so I don't know how much more there is but yeah, just some thought
