Community-consensus threat estimate for RimWorld 1.6. Actual raids scale with wealth, population, days survived and storyteller settings.
Managing Raid Size
Raid size scales mainly with colony wealth. Keep valuable items in stockpiles behind defenses, avoid hoarding thousands of silver, and build kill-boxes, turrets and walls before the 200k-wealth mark when raids get serious.
RimWorld Raid FAQ
What determines raid size?
Wealth, colonist count, days survived and difficulty. More wealth = bigger raids — spend silver on defenses and equipment.
How do I survive a siege?
Mortars counter sieges; keep a trained artillery pawn and shell stockpile ready.
