Polarities Mod/Star Construct

Star Construct is a Pre-Hardmode boss intended to be fought at around the same time as the Eater of Worlds or Brain of Cthulhu.

While it is alive, its exclusive Cosmic Screaming will play; if the Polarities Mod Music sidemod is not enabled, the vanilla track Boss 1 will play instead.

Spawning
The boss will occasionally fall from the sky at night as a Dormant Construct when the player has over 200 maximum life that must be damaged to awaken it and begin the battle, or it can be summoned manually with a.

Behavior
When awoken, Star Construct will unfold from its dormant star-shaped form, extend four grappling hooks, and begin chasing the player with a scream. By default, it holds its hooks near its body and chases the player along the ground, jumping if they go above it, but it will occasionally use one of the following three attacks, avoiding repeating the same attack twice if possible.


 * Hook Grapple- Star Construct extends its hooks to latch onto tiles near the player, pulling itself to them. The construct will periodically move its hooks closer to the player if there are available tiles within a certain range. The construct will always use this attack when too far from the player as long as it has active hooks, allowing it to catch up to them from a distance. The attack cannot be used if no hooks are active.
 * Hook Swing- Star Construct stops and swings its hooks around itself, which speed up and get further away from the boss before beginning to release star bolts outwards in all directions. The attack cannot be used if no hooks are active.
 * Starfall- Star Construct leaps high into the air, retracts its hooks, turns into a star form, and launches itself downwards at the player, taking into account the player's velocity when doing so. If the boss is below half health, it will release a burst of damaging fallen stars from the point of impact.

In Expert Mode, both the construct and its hooks move somewhat faster. Additionally, when a hook is killed, it will detach from the main construct, alternating between dashing at the player and shooting a pair of star bolts towards them, persisting until the boss is defeated.

Aftermath
Once the Star Construct has been defeated for the first time, the following will occur:
 * s and s will begin spawning naturally.
 * The will begin selling.

Tips

 * The boss has a very high maximum speed, but it accelerates very slowly, meaning rapidly changing direction with a Hook or the Shield of Cthulhu can help throw it off. Since the boss always jumps if the player is above it (with a short cooldown), jumping upwards can cause it to leap over the player rather than colliding with them.
 * It's best not to get too far from the boss in order to avoid being caught outside of the safe zone during the hook swing attack. This attack is also a good time to damage the boss, particularly for melee players or summoners.
 * Using a piercing weapon means the player can directly damage the boss without having to worry about its hooks getting in the way. However, in expert mode, it can be helpful to avoid damaging the hooks if possible, as the detached forms can complicate the fight significantly.
