Treasure Sense
Treasure Sense is a lps upgrade in Loot Grinder, the free medieval idle clicker.
What it does
It increases your total loot-per-second by 15%. (+15% loot per second.)
Cost
It costs 300K loot and is a one-time purchase.
Why it’s useful
Because it lifts your whole loot-per-second rather than a single building, this is the kind of upgrade that pays for itself almost immediately and keeps paying forever.
