Hey, in the description, not sure if you meant it to be spelled metal, but the correct word in that sentence is mettle. As in "Test your mettle".
It's the second paragraph "Wield a variety of killing instruments and abilities to test your METAL against towering, bone-chilling bosses. Explore a twisted Lovecraftian world shrouded in darkness and madness. RPG elements allow you to customize your battle experience to your liking, from your character’s appearance to skills, stats, and weapons."
