Blunder Booster's electric aura

The Blunder Booster is a craftable post-Moon Lord accessory that is the direct upgrade to the Plagued Fuel Pack. While equipped, rogue damage is increased by 12%, projectile velocity is increased by 15% and stealth generates 10% faster. Additionally, a red aura is summoned around the player that damages enemies and inflicts the Electrified debuff.

Pressing the Booster Dash key causes the player to dash diagonally upwards in the player's direction at the cost of 25% of the player's stealth, leaving a trail of damaging red lightning bolts.
