Great Thunder Idol

The Great Thunder Idol is a craftable Artifact accessory. It increases movement speed by 50% and armor penetration by 5. Additionally, a burst of 8 lightning bolts is released from the player whenever they are damaged. The lightning bolts scale in damage and speed throughout progression: by default they deal 10 damage, in Hardmode they deal 40 damage, and post-Moon Lord they deal 100 damage.
