Agricultural Tools
Agricultural Tools is a synergy upgrade in Loot Grinder, the free medieval idle clicker.
What it does
Every Farm you own boosts your Blacksmith buildings’ output by 0.10%. (Farms boost Blacksmiths by +0.1% per Farm.)
Cost
It costs 75K loot and is a one-time purchase.
Why it’s useful
Synergies scale with how many source buildings you own, so they keep getting more valuable as your kingdom grows.
