The Ebon Vault: Orbs of Power (PFRPG) PDF

This pdf is 28 pages long, 1 page front cover, 1 page editorial, 1 page advertisement, 1 page SRD and 1 page back cover, leaving 23 pages for the orbs, so let's take a look at them!

Orbs have long been a rather neglected iconic piece of mage's apparel in D&D and PFRPG and this pdf sets out to change that. At first sight it seems like all the slots are taken for magic items, so what do orbs do? Well, they serve as a magic amplifier of a sorts, which I consider a good idea.
The orbs range from 8000 GP to artifact-level and the pdf kicks off with a nice piece of IC-writing. Additionally, we get two feats, one to craft orbs and one to channel spell-like abilities as well as through the orbs along some insight into the design-process. The items come with short descriptions, which is a nice plus. Without further ado, these are the orbs:
-Dragonscale Orb: Depending on the color, they can change the energy of a spell and grant minor spell-like abilities and can once per day panic opponents.
