There are a total of 236 chests containing items and 7 chests containing GP. GP values are chosen using a triangular distribution between 1 and 65535. Items are divided into tiers I through S. Each chest randomly selects a tier using corresponding weights. For tiers I through A items are selected using a uniform distribution. Items in tier S each have their own individual weight.

As examples,
8.5% of the 236 chests will contain an item randomly selected from tier A using a uniform distribution. Therefore, each seed will contain an average of 0.085 * 236 = 20.06 tier A items and each item in tier A will have an 8.5 / 25 = 0.34 percent chance of being in each chest.

0.5% of the 236 chests will contain an item from tier S. Of those, 10% will contain a Valiant Knife and 2% will contain a Paladin Shield. Therefore, each seed will contain an average of 0.005 * 236 = 1.18 tier S items, 0.005 * 0.10 * 236 = 0.118 Valiant Knives (~1 in 8 seeds) and 0.005 * 0.02 * 236 = 0.0236 Paladin Shields (~1 in 42 seeds).

NOTE: The cursed shield is excluded from all tiers and will not appear in chests.
