Spectre
Spectre is a legendary two-handed poisonous hammer.
A powerful battle axe. Its razor is made out of 
stardust energy and can change its polarity on a whim.
These energy swaps, while spectacular, are quite unstable. Therefore, the Spectre tends to suffer from elemental offsets, where some of its abilities might get the element change with a certain delay.

Species descriptions:
- Alta: A tool that uses spectral projection and stardust to manifest energy in form of spectral elemental analogs. No idea what I’ve just said.
Radiomessages on pickup:
- You’ve just picked up an alta weapon, or an “energy tool”, as they call it. According to my database, these usually have an extended set of features. I suggest reading its description.
