This is wonderful in its simplicity and accessibility. Could you share a sentence how you see positive conditions work + how you see spells work in this system?
I’d use spells straight out of B/X. Everything should convert, and they’re available for free. So, if I were to cast day “spider climb”, it just places a temp condition in your inventory called “spider climb” , and it expires two failures later (as a consequence). The limits of the tight format, sorry!
