During combat, one can farm coins using the Crimson Rod near the door, damaging enemies trying to break in. Mystic is also a good alternative for mana conservation. The Crimson Rod could benefit from Deadly or Demonic Modifiers, increasing each blood droplet’s damage. On all game versions, the blood droplets can pierce one enemy or a solid block before dissipating.

Reusing the magic weapon will reset the Cloud’s duration and replace it. The Crimson Rod can only spawn one Crimson Cloud, unlike the Nimbus Rod. The Crimson Rod is a weaker counterpart of the Nimbus Rod. Moreover, it can travel through open doors, platforms, and liquids unhindered. The spawned Crimson Cloud lasts for 5m (desktop, mobile, console) / 1m (3DS, old-gen consoles).

Due to the Rainbow Rod's high damage output and homing effect, it can be quite useful when fighting many Hardmode bosses including Plantera and Golem.The Crimson Rod is a magic weapon that summons a Crimson Cloud to the cursor’s location or upon colliding with a solid block that spawns damaging blood droplets for 5s.

Due to the projectile's sharp homing, it is possible for it to turn around after piercing an enemy and hit it again.

This means the player does not need to be as precise when directing the projectile through caves or tight enclosures in worry of accidentally destroying the projectile. Only when it is out of the player's control will it explode upon hitting a surface. You can also use the Lavaproof Fishing Hook. After the 25th quest, you’ll a 1/75 chance of getting the Hotline Hook after an Angler quest. To obtain Hotline Hook, you need to first play in Hardmode.

Unlike the Magic Missile and Flamelash, the projectile will not dissipate if it hits a surface while being controlled. The best rod is the Hotline Hook fishing rod, which allows you to fish in lava with no other specialized gear.

Opening the inventory (and then closing it in singleplayer) will make it fling in the direction the player's finger was moving.

Hovering over any slots in the inventory (should it be open) will cause the loss of control of any controlled projectile, flinging it forwards in the direction the cursor was last moving.

(Desktop, Console and Mobile versions) The Rainbow Rod can be used in conjunction with Binoculars to increase the range of the projectile.

The Rainbow Rod can be used to light areas remotely.

(Desktop, Console and Mobile versions) Tips On the Old-gen console version and Nintendo 3DS version, the projectile is a light orb shifting through rainbow colors with a rainbow trail. It can move through liquids (unlike the Flamelash), and can pierce twice before exploding and dealing damage in a small area. The missile will not disappear when touching a block if it is being manually controlled. If any enemies are nearby, the missile will home in on them.

On the Desktop version, Console version, and Mobile version, the projectile is a white-sparkling missile with a rainbow trail, and it emits a moderate amount of light that rotates through the entire color spectrum. If the cursor is stationary on release, it continues along the angle formed from the player. If ⚒ Use / Attack is released mid-drag, the missile will be flung in that direction. The projectile can be controlled by holding ⚒ Use / Attack and moving the cursor. The Rainbow Rod is a Hardmode magic weapon that launches a controllable projectile, just like the Flamelash or Magic Missile, and can be considered an upgraded version of them.
