Philosophers Stone
CASTINGS: 1
TARGET: One1 creature or object within 5 yards
DURATION: 1 minute
You create a stone that allows you to turn anything into gold. Make an intellect roll against the target’s agility. On a success, the target instantly loses 8d6 health and becomes slowed (luck ends). Each time the targets gets a failure on the roll to end the affliction, it becomes held until the end of the next round and it loses an additional 4.6 health. A creature reduced to 9 health is turned to gold permanently. If carved up, the gold is worth its normal value and does not change back into the target. You can touch multiple creatures with the stone for the duration of the spell
