Two thumbs up

It seems odd that an extra normal action costs 4 points and Cheat Death only costs 3 point, other than that seems good.

Maybe have a cost to learn a move outside of your style and limit to 1 or maybe 2 outside moves per Tier

You might want to look at BMI (Body Mass Index) which is used by the Health industry to determine healthy Wts to establish base wts, then increase or decrease what would be a healthy BMI based on race and Str (muscle mass), once you have a base you can determine underwieght, avg, overweight and obese ranges

There should be an off-hand penalty as well I would think.
If you have Libram #11 you might consider making a Gunslinger Combat Style using those as a guideline.

#1 has Spell construction rules, in combination with #10 that gives you just about everything you would ever need for Magic.
#2 Adds the Shaman, Sorceror and Warlock and spells for Black Magic, Spirit Magic, and Sorcery also has a section on the planes
#3 has rules on building classes and shows how the base classes were built, also has a bunch of Talents
#4 Adds Beastmaster, Monk, Ranger, and Warrior Mage and their spells
#5 expands on craftsmanship and Herbalism  also introduces Training Paths
#6 has Different Spell Drain options, information on Commerce, and alternative ways to resolve actions
#7 has rules for Creating Races and adds several new ones including Centaurs, Gnomes, and Lizardmen
#8 is all about options including Combat Style creation rules, expanded action points, expanded initiative options, etc.
#9 Adds Bard, Mage Hunter, Paladin and Shadowkin classes and their spells.
#10 as previously mentioned has the Magic Item Creation rules

I like #1 because I like the option to create my own spells.  I like #4 and #9 because I like to have those sorts of characters available to play.  I like #7 because it is easier to make a custom world seem unique if you can add a custom race or two.  I don't have #10 yet but I always like building odd magic items.

Hopefully this helps

So first up I thought I might ask a question on the Magecraft skills.  The rules say:
"Characters may also learn specific instances of this skill for other purposes. These include, but are not limited to Magecraft: Alchemy (the base skill used in item creation), Magecraft: Runes (used to make scrolls), Magecraft: Circles (used in creating Circles of Protection and Thaumaturgic Triangles for, among other things, summoning; see p. 82), and specific magically related lore skills, such as Magecraft: Undead Lore, Magecraft: Demon Lore and Magecraft: Devil Lore, just to name a few."

There doesn't seem to be a more definitive list of the various skills under Magecraft and how to use them - that is no rules on item creation, scroll creation, etc.  Am I missing them? (quite possible as I only just bought the rules yesterday).

Welcome, always good to get a new member.

Libram Novus #10 has the Magic Item creation rules you are looking for.
