Arrow Cost

[astromath]

Player's Handbook (both Legacy & 2024)
The cost of 20 arrows is 1 GP. This means the cost of each arrow should be 5 CP (1 GP/20 =0 .05 GP = 5 CP), but you have 5 SP instead.

I'll note that for fixing.

It pays to buy in bulk!
Costco, a 4000 arrow pack for only 129GP, you only need a mule train to take them home!
