Using the North Pole to attack Target Dummies. Note how the main projectile dissipates upon contact with a solid block or upon impacting a third enemy.
The North Pole is a Hardmode, post-Planteraspear that is dropped by the Ice Queen during the Frost Moonevent with a 5.19%–10.37% (15.56%–31.11%) chance depending on the current wave.[1] When thrust, it fires an icy spear projectile that is unaffected by gravity until after traveling for 0.5 seconds. It can pierce enemies twice and cannot pass through blocks. The spear also releases a trail of damaging snowflakes that rain down, dissipating upon contact with an enemy or block.
Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount. However, Ruthless might be preferred if the player already has very high critical strike chance.
Notes
The North Pole has a maximum range of approximately 13.36 tiles.[2]
Melee speed bonuses can slightly increase its range, in addition to increasing its attack speed and projectile fire rate. They also allow the icy spear projectile to travel faster and further.
The icy spear projectile deals 100% of the weapon's damage (80 base damage) and 85% of its knockback (5.695 (Average) base knockback).[2] The snowflake projectiles deal 70% of the weapon's damage (56 base damage) and 46.75% of its knockback (3.132 (Weak) base knockback).[3]
Traveling horizontally, the icy spear projectile moves at a speed of 58 mph.[2]
After the icy spear projectile is fired, it takes an average of 0.18 seconds for the first snowflake to spawn. Afterwards, the rest of the snowflakes spawn at fixed intervals of 0.13 seconds.[3]
The icy spear and snowflake projectiles automatically dissipate after 2 seconds and 4 seconds, respectively.[4]
The icy spear projectile is fired from the tip of the spear at the apex of its thrust, as long as the player's line of sight to tip of the spear is not obstructed by solid blocks.[2]
The projectiles are affected by liquids; when used underwater they move 50% slower and travel half the normal distance before being affected by gravity and arcing downwards very sharply. This does not reduce the number of snowflakes spawned per projectile, however, leading to a denser cluster of snowflakes.
Tips
Fighting enemies with the North Pole out in the open gives it a huge advantage, especially when tackling groups of enemies during events. The North Pole's snowflake projectiles can easily fall upon and dispatch multiple targets at once.
Aim the North Pole straight up and launch the spear upwards, allowing all the snowflakes to descend and rain damage against large targets. This has a much higher rate of damage than even the Solar Eruption or Daybreak and can destroy weaker bosses or immobile targets like the Celestial Pillars with ease.
Trivia
The North Pole is the northernmost point of the Earth, traditionally stated as the location of Santa Claus's home and workshop. Being a spear, like a pole, it uses the North Pole as a pun for it being dropped during the Christmas-themed Frost Moon event.
The North Pole is the only weapon obtainable from the Frost Moon event that has a 07*rarity while the others have the 08* rarity.
The North Pole with its unused slash enabled.
There is unused and disabled code for the North Pole that gives it a slash similar to that of the Gungnir. It appears blue in game and uses the default sizing for this effect.[5]
Now spawns half as many projectiles, but the damage of the spear projectile now deals base damage and the snowflakes deal 70% base, compared to the previous 80% for the spear projectile and 64% for the snowflakes.
Removed the projectile cap.
Removed the impact of wind on snowflakes. Their spawning position is now semi-randomized, so that they do not all fall in the exact location.
Spear and snowflake projectiles now have a much shorter projectile lifetime.
