Ok, persuasion check: [roll0]
Depending on result, roll [roll1] or [roll2] times on Table (A-I)
So three times on Table C.
Rolling three times on Table C:
[roll0] - potion of invulnerability, rare
[roll1] - horseshoes of speed, rare
[roll2] - potion of healing (superior), rare
Alright, so an excellent assortiment, but unfortunately way too expensive. The minimum cost for such a rare item (as it's 2d10 x 1000 gp, half price for potions) is still 1000 gp! So 100 gp out of the bank for asking, 400 gp left.
I'll just get regular potions of healing instead.
Edit: Wait a second. It says you can also use results from a lower table. If I roll those same numbers on Table B, a more realistic assortiment becomes available:
spell scroll (3rd level), uncommon
rope of climbing, uncommon
potion of healing (greater), uncommon
That rope of climbing is interesting. It only costs 1d6 x 100 gp! Let's hope I can afford it. (Roll in next post.)
