Orders reference

Craft Make an item the facility supports; it can’t craft something else while the work is in progress.

Empower Grant a temporary benefit to you or another creature.

Harvest Gather a facility’s resource; harvests similarly occupy the facility.

Recruit Bring defenders, creatures, spellcasters, or other personnel to your Bastion.

Research Have hirelings gather information over the facility’s listed time.

Trade Buy or sell goods and services through the facility.

Maintain Applies to the whole Bastion, forbids other orders that turn, and prompts one event roll.

Spaces. Cramped = 4 five-foot squares; Roomy = 16; Vast = 36. Squares may be configured across multiple stories.

Free details. Include closets, washrooms, corridors, ramps, staircases, doors, shuttered windows, secret doors, and portcullises within a facility.

New basics. Cramped costs 500 GP / 20 days; Roomy 1,000 GP / 45 days; Vast 3,000 GP / 125 days.

Enlarge basics. Cramped → Roomy: 500 GP / 25 days. Roomy → Vast: 2,000 GP / 80 days.

Walls. Each 5-foot square costs 250 GP and 10 days. Complete walls reduce Attack-event loss dice by 2.
