Portal Gun



The Portal Gun is a Hardmode, post-Moon Lord tool which is always dropped by the Moon Lord. It launches projectiles capable of creating up to two portals (one fired by hitting, the other by hitting ) upon impact with blocks. These two portals are linked; any player that touches one will be instantly transported to the other one, without losing momentum. While NPCs can be teleported with the Portal Gun, enemies or projectiles cannot.

The Portal Gun has a maximum range of 675 blocks (1350 feet). It takes about two seconds for the projectile to travel this distance.

While selected, the Portal Gun will alter the player's physics: their maximum fall speed is multiplied by 3.5 (from to ) and horizontal momentum/inertia is kept while in the air. This effect is also applied if the last entity that affected the player's fall was a portal. The extremely fast movement may cause performance losses on some computers.

Tips

 * The increased fall speed can be converted into horizontal movement speed by placing the "outlet" portal on a horizontal surface. Falling into a portal at results in the extraordinarily high horizontal movement speed of . This can be utilized by equipping high-tier wings and placing the "outlet" portal in a high, open area.
 * It is possible to apply this conversion of vertical to horizontal velocity to the ridiculous speeds gotten with the . With an ideal set up (that being a water chute with two portals inside at the top, stacked right on top of one another, and entering the water chute at the maximum possible distance without destroying the portals then aligning to the side the portals are on), the player can reach horizontal speeds of at least, and with accessories such as the and , they can maintain the speed and navigate around obstacles (to a degree). However, since the Portal Gun is acquired post-Moon Lord and the setup does take some effort, it is likely to be more of a novelty if a player has other methods of fast travel such as Pylons, which they are likely to have by that point in the game.
 * The increased fall speed can also be used to fall through hellevators faster.
 * With enough training, players can entirely avoid an enemy's or boss's attack using the Portal Gun, then immediately return to that enemy/boss to continue fighting.
 * Grappling on a portal can launch a player depending on the direction of the portal, similar to how doors behave when grappled.

Trivia

 * The Portal Gun is a direct reference to the 2007 puzzle-platform video game . In Portal, the gun is the primary game mechanic, shooting portals that allow the player to travel great distances in a short amount of time. Additionally, the Portal Gun shoots orange and blue portals, the same colors as in the original game. Unlike in Terraria, the portals cannot be placed on every surface even if there is enough space for the portal. (However, with the introduction of Anti-Portal Blocks in, there is a type of surface that disallows portals in Terraria as well.)
 * The Portal Gun being dropped by the Moon Lord is a reference to the ending of , Portal's 2011 successor, where the player must shoot a portal into the moon in order to defeat the antagonist of the game.
 * The maximum speed a player can obtain through the use of the Portal Gun is the same maximum speed as in Portal.
 * Despite being dropped by Moon Lord, it still only has a rarity of.
