Etherial Tank

The Etherial Tank is an Expert Mode-exclusive accessory dropped from Steam Train when defeated in the Etherial Dimension. While in the Etherial, the player's jump speed, movement speed, and maximum run speed is increased, and all damage modifiers are increased by 1/25 of the player's horizontal velocity. Additionally, making contact with an enemy will cause them to lose health equal to 500 times the player's horizontal velocity; this is not an attack, and so does not check the enemy's defense. The damage dealt will not kill the enemy, and it will leave them with a minimum of 1 hp.
