Fantasy Isekai

Intro You were exploring an abandoned mansion and find an amulet. It whispers for you to touch it. It isekai's you into a large arena with 99 other people. A pop-up window appears in front of you. It welcomes you to the world of Sedona. It informs you Sedona has video game rules. Materials/forgables respawn at the beginning of every week. People don't have stats; do have health and stamina. Spells use stamina, not mana. Higher level spells use more stamina. Armor, weapons, accessories have stats. Items can be upgraded and fused. A keypad pops up and the screen tells you to pick your equipment, abilities, and spells. You have 5 minutes to prep before the hordes start. (Be anyone) (voice is random) (amulet doesn't travel with you)
