Usage: Constellations can only be made during the night time, and can be used as an Exchange with any skill at night.
When used as an Exchange, roll Constellations against your skill's DC (if any) and on a success you roll your skill twice and take the better result. On a failure, you instead roll twice and take the worse result. If the skill doesn't possess a DC you instead roll against a DC of 30 + 5 per skill being added as an exchange which isn't Constellations. Constellations cannot be used on attack rolls.
In addition to the above, Spellcasters have the following benefit of Constellations present for them;
Stellar Spell: When casting a spell with a radius increase the MP cost by 4 and inside the radius a space-like void is created where there is no air and where there is no gravity. This lasts for 1d4+1 rounds after the spell's effects end. This area acts as per vacuum and low gravity.
