I ran a group of 4 players through the Tier 1-2 of this Scenario. The Chronicle indicates that the total "Max Gold" was "453;" however, I believe it should be 553 Gold. Let me explain:
Act I Rewards:
Tier 1-2: Give each player 53 GP
Act II Rewards:
Tier 1-2: Give each player 128 GP
Act III Rewards:
Tier 1-2: Listed under Development is indicated that if the PCs open all 5 of the safes, then they are awarded 100 GP each
Act IV Rewards:
Tier 1-2: Give each player 5 GP
Act V Rewards:
Tier 1-2: Give each player 267 GP
Total = 53 + 128 + 100 + 5 + 267 = 553 GP
What I believe is that the Max Gold on the Chronicle ignores the potential reward for Act III.
