Looking to expand the Kelyn NPC from the previous post. The post about his unusual companion, Mishabroo, contained information about the mage at various levels. I hope to make it into a PDF with full stats of Mishabroo, two (only two) new proficiencies, new spells, new creatures and hopefully some new magic items. April is really busy, so I'm not sure of the timeline.

It will be stated per the ACKS rules, but hopefully won't be too hard to adapt to other systems.

I worry about proficiency inflation, so I only add two. One of them is a mage class proficiency related to mages that train under Kelyn. It will be similar to the Black Lore of Zahar proficiency. The other has to do with Kelyn's ability to quickly create formulas for magic items.

The spells will deal with Kelyn's unusual focus on constantly improving Mishabroo, his fear of teleportation and psionicists and his dislike of blasting spells like Fireball and Lightning Bolt. One of the spells will be Call Primordial - this is related to a series of posts I did on primordials a few months ago. Some of the other spells, including ritual spells, will come from the SRD.

The new creatures will initially come from his early cross-breeds and constructs. Kelyn has a preference for constructs, mostly because he is trying to duplicate Mishabroo and is unable to do so. Other creatures will be stated forms of the primordials mentioned earlier.

Kelyn won't have a fully detailed repertoire in order to allow GMs to customize him into their campaign. The snapshots of Kelyn through history should also allow adventures in time.

As far as the new magic items, a couple of them will appear to be of little use to the PCs. Hopefully these items can serve as hooks for possible new quests.
