Crimson Rod

The Crimson Rod is a magic staff that can be obtained from breaking Demon Hearts in the Crimson. It launches a reddish rain cloud towards the cursor, where it rains blood droplets downward onto enemies below. The cloud projectile does not pass through terrain, instead stopping if it hits a surface before it reaches its target location. As well, its coverage area is rather narrow, making it difficult to use in open areas or against agile foes. The droplets pass through all enemies, and the droplets fall for around 20 blocks or until they hit a solid object. Thus, it can be used to great effect against larger foes and clustered enemies, if you can lure them into the rainfall and attack them with another weapon whilst they are still taking rain damage. The fact that the droplets deal relatively high knockback combined with a long projectile duration makes this weapon ideal for area denial and base defense during a Goblin Invasion or Blood Moon.
