Yeah, that’s part of why I created an occult spellcaster. As far as I understand, Soothe heals both living and undead PCs.
Yes, can confirm that should be how it works. Taking the Cauldron feat would also grant you 2x Oils of Unlife/Healing Potions, should you choose to go down that route.
I had a look at your spell list. I like that you've got most of the good stuff (Haste, Soothe, Befuddle, Gravity Well, Heroism, Slow) but you could probably use some things that boost your own subclass. Spells that cause Blinded/Concealment/Hidden (Revealing Light, Darkness, Ocular Overload) or make your own familiar invisible (Invisibility) would be good. I'd cast them on you, but I only have 4 flexible spell slots and my 2nd rank ones don't allow me to cast any of the above on you or your familiar.
You've also forgotten to add the spells granted to you from your Patron to your spell collection - these are Fear (Starless Shadow) and Sleep (Lesson of Dreams).
To best make use of Ceremonial Knives, you ideally want multiple disposable 4sp daggers to use as a wand that you can overcharge and get back the next day.
I think that's a good idea, Yiks. This is likely to be a mixed undead and living party, so healing might be a problem. So far the only source of healing is Battle Medicine from our Battle Oracle, so Robust Health is a must take imo. We don't have anyone capable of casting Heal/Harm.
"I have already suffered death from the hands of those filthy Iomedeans. Now I hunger to give those do-gooders the violent end they deserve - by my hands."
Mataranka Cherenov was once a mortal Magus that used his magic and bowmanship to wreck carnage and destruction in Mendev. He would do so subtly, using his Stealth and Invisibility to stalk his foes, tormenting them with the knowledge that a violent death was lurking close by. Once satisfied that his deity was happy with his actions, he would Spellstrike them from a distance, enjoying the carnage that was a body exploding from raw magic pumped into them by bowshot.
Eventually, some do-gooders from the Church of Iomedae caught on to his actions. They chased him out of the city and towards a deep, dark chasm. Rather than stand trial for his crimes, Mataranka lept from the precipice into the abyss, laughing all the way.
When he woke up, it was with a long forked tongue, a still heart and a hunger for flesh. It appeared that a Ghoul had fed on him, giving him their curse - but also providing him with a second chance at unlife. With praises to Ananshea on his cold blue lips, the Magus picked up his bow and prepared to take revenge on the Church that had denied him his rightful prey. This time, he promised himself, he would feast not just on their fear, but also on their flesh.
Who is our villain?:
Mataranka Cherenov is a level 7 Starlit Span Magus with the Ghoul Dedication. He's the brains of this operation - with his expertise in Occultism, Society and Stealth, he will deal quick, explosive and silent death upon anyone unlucky enough to cross him. A ghoulish, sadistic grin is spread across his face at all times. On his bare chest, he has emblazoned the Faith Tattoo of Ananshea - The Skin That Walks on Teeth. A row of sharp teeth dripping with blood glows a sickly red at all times, marking him as a truly Unholy and detestable creature.
Edicts:Annihilate any worshippers of Iomedae, enjoy every kill to the fullest - while Mataranka will work with others willing to help him get kills, each kill is a unique piece of art and he's armed with a scalpel, ready to carve chunks out of any victim into a bloody masterpiece. His grudge against those that caused to his death fuels him - nothing less than the annihilation of any Iomedean he sees will do.
Anathema:Hold back in a fight - in the words of Emperor Palpatine: "There is no mercy."
