Astra is a versatile resource that enables unique magic effects in your fantastic adventures.

Many formulas can be found in the world of fantasy and each one explains the methods to imbue a raw astra crystal with magical properties. Raw astra can be found, mined from special veins, or even extracted from other items. Once available, raw astra can be refined in the form of a colored crystal that just floats around its carrier, ready to be used anytime with a bonus action. 

Please note that any area or distance effect follows the guidelines for narrative combat by Sly Flourish and that the concept behind Astra is inspired by the innovative Harbringer's settings by Absolute Tabletop.

Astra is what we call "campaign aspect": a unique element of our role playing campaign. It is especially designed for sci-fi D&D adventures as it gives to the players an additional layer of character development. As a dungeon master you can choose to emphasize the flavor or the mechanics as you see fit for your own table. Give it a try, integrate Astra and enhance your campaign!
