北极星

• Star Friends - If the player also has [毛绒星星] , while [毛绒星星] is active and Polaris is held, the player continually fires maximum level Polaris shots in all directions.
• Square Brace - If the player also has [支架钥匙] or [仿生腿] , Polaris gains 20% increased damage, increased ammo capacity of 700, increased magazine size of 30, increased fire rate when leveled up, automatic firing, and a new appearance. The distance between the two bullets that fire at level 2 is wider with this synergy.
• The gun does not change appearance between levels with this synergy.
• Taking any damage, even while the gun is not equipped, will decrease its level.
• Taking damage while at level 1 resets any progress made towards the next level.
• Dropping Polaris will reset its level.
• Level 2 requires killing 11 enemies of any type, while level 3 requires an additional 20.
• Polaris's level does not affect its selling price.
• While level 1 and 3 fire a single projectile of varying damage, level 2 fires two. Because of this, level 2 projectiles have double the probability of gaining chance-based bullet effects (e.g., [斩首子弹] , [武士刀子弹] , [饥饿子弹] , etc.).
• When used alongside [螺旋子弹] at level 2, the two bullets fired follow the same helical pattern instead of cris-crossing one another.
• Prior to the [空投补给] Update , Polaris had 400 maximum ammo.
• The symbol for reaching level 3 appears every time after killing an enemy once Polaris is at level 3 and it has killed a large amount of enemies.
• If Polaris is combined with another weapon with [胶带] it fires all 3 levels every shot, consuming 3 ammo. It does not change level if the player takes damage.
• Prior to the Advanced Gungeons & Draguns Update , Polaris had 0.07 fire rate.
• Trading hearts with the Vampire will not affect the level of Polaris.

• This gun is a reference to the Polar Star from Cave Story . Cave Story's weapon leveling mechanics are also the inspiration for this weapon's abilities.
• The "two small tick marks" refers to Quote ("), the main playable character of the game.
• The synergy Square Brace is a reference to Curly Brace, a robot character in Cave Story.
• Its altered appearance due to the Square Brace synergy is identical to the Machine Gun from the same game, which replaces the Polar Star upon obtaining it from Curly Brace.
• You can infinitely farm levels by killing the jammed Spent the Gummy spawns. Some more limited forms of farming can be performed with Killithids' clones or Ammomancers' Shelletons.
