Sir Zarek
Sir Zarek is knight #19 of 25 you can recruit in Loot Grinder, the free medieval idle clicker.
Backstory
Zarek emerged from the eastern wastelands with a blackened helm and an army loyal only to fear.
What knights do
Your highest-ranked knight sets a kingdom-wide casualty shield that reduces how many peons your disasters — dragon attacks, goblin raids, tornadoes, plagues and more — can claim. The shield is back-loaded, so each knight you recruit is worth more than the last, climbing toward a maximum of 75%.
Recruitment cost
Recruiting Sir Zarek costs 18B loot — a one-time purchase.
Why it’s useful
Disasters strike whether you’re ready or not; a recruited knight turns what would be a population wipeout into a survivable dent, keeping your loot-per-second steady through the chaos.
