Powder Hall Build Notes

Section titled “Powder Hall Build Notes”
Use CaseWhat To Do
Demolition carryBuy it after Demodwarves, cooldown, and package damage are already useful. Powder Hall is a scaling unlock, not a replacement for the basic bomb engine.
Scientist supportBecause Powder Hall needs Scientists, it pairs naturally with Scientists Guide routes and later artillery or alchemy plans.
Artillery bridgePush toward tier 4 when Nuclear Research or rocket/nuke scaling is the next goal.
