Upsilon Carinae

Upsilon Carinae is a very powerful blue magic weapon in Misery of Magic, acquired in the Solitude Stoneway through a unique process.

Effect
Similarly to its un-upgraded version, Upsilon Carinae begins by launching backwards. Then, a moment later, it produces a small back-blast while emitting a beam focusing precisely on the target, without hitting anything else. It targets the cursor at the moment the beam fires rather than the moment the weapon was released.

Obtaining
The first step to getting Upsilon Carinae is to first obtain Broken South Star, which is a significantly weaker white version of itself. It is found in a box in Sorrow Peak. Getting to it requires solving an optional, harder puzzle in a side room in addition to the main puzzle needed to complete Sorrow Peak.

Once that has been done, one must then head to the Ocean Monument in Solitude Stoneway. Interacting with the shrine there causes Broken South Star to transform into Upsilon Carinae.

Trivia

 * The real life star system Upsilon Carinae contains two blue stars, and in the far future when Misery of Magic takes place, it will be the South star.
 * Acquiring it causes the text of the shrine to permanently change.
