Okay here's my problem.
In a game I am given the choice of two arrows:
1. Normal Arrows - 3gp (cost) - 1 damage (for each successful hit)
2. Iron Arrows - 5gp (cost) - 2 damage (for each successful hit)
As a character, I have a certain chance of hitting with every arrow I fire (which is the same for either arrow), and this chance increases as my character develops. What I would like to know is; What chance do I have to have of making a successful hit for it to be worth me purchasing the 'Iron Arrows' as appose to the ‘Normal Arrows’ (because whenever you miss you waste 2gp more with the ‘Iron Arrows’).
Thanks a lot =)
