Dungeoneer: Vault of the Fiends - Treasure Chamber

Hello! The problem is that when I enter Treasure chamber I may play a treasure for free to get peril equal to the glory value of that card. But in solo I don't use peril list at all (when I visit a location I've to play beasts instead of getting peril). So if I play a treasure which costs 3 glory, should I play 3 beasts or still get 3 peril? Because in this case I get peril for the card ability, not for the entering a location.
