Hey, thanks again for your comment. You've actually picked up on a huge copy paste mistake there. All the tables are put together in excel and then copied in.. I'll definitely get that fixed straight away, especially as its such an important table!
the 5-6 next to Moderate Potions is supposed to be 2-6. As in, roll d6 to find out if you've found one of the simple potions or if you get to roll d66 on the larger table. I think i need to make that more obvious.
For the clarifications:
I generally handwave thirst and water. One group I know include it as part of a Ration, which seems to work well enough. I think anything beyond that and it starts to defeat the simplification idea behind forge.
I don't, actually. I generally insert the creature wherever I initially imagined it to be. But I think there's a good argument for adding encounter range onto the bottom of page 37.
I admit that the variable potency of crafted Potions probably works best for healing Potions and poisons, but I think it's also interesting if someone tries to brew a potion of fly, but they end up with levitate.. or if they were trying for a potion of strength and ended up with giant strength. I think this will definitely require some GM thinking. Alternatively, you can ignore variable potency for Potions where it's a bit ambiguous, and just roll d4 on complication/added bonus.
Correct, runes and writs all contain a single spell, however that spell may be cast multiple times, based on how many spells a character can cast per day.
I have a fair few other fixes that i need to make, in addition to those above, however I'm hopeful that I'll be able to upload v1.0 by the end of the week.
