But what if the charger is a barbarian with a battle axe?

I would allow any weapon to be used, with the obvious caveat that the longer weapon strikes first (which already is incorporated), so if your opponent is charging with a battle-axe and you wave a 2H sword you are good to go.

And yes, it is already a Full Action (two Half Actions, actually, one for the Set, the second Half Action for the attack)

This may need clarification, personally I don't se a Set as an attack, you are letting the opponent to attack themselves, so it should be resolved in another way, maybe base weapon damage + bonus based on movement speed

1/2 action should be a kind of "Hold/Wait" action and the other 1/2 would be setting the weapon
Maybe you can Ready & Set as a full action or just Set as a 1/2 action with some penalties/drawbacks
Ready & Set is the classic move use in action movies, where the warriors hold until the enemy is at the correct distance
Set alone is more horror movie where the victim use a "Weapon" on the last second against the monster/bad guy

I know this my be to involved for FX but I like having options

Sorry to hear about her, good to know she's better now.

In these kind of games, differentiation between characters goes more with roleplaying and both what skills are increased and how they are used.

Caster get more spells, but they have to put points in them and they can use them a limited set of times (due to mana costs), non-casters can build on skills that will always be available (it will only depend on environmental factors to be used).

I'm sure Razyr will publish rules for Combat Styles and Moves/Techniques sometime in the future.

But you can always let players try to do "special moves" using skill penalties and Success Levels.

Barbarian is a culture, maybe you are referring to a Barbarian Berserker/Berserker.

Ranks from Culture and Vocations aren't purchased thus do not count towards the 2 times purchase limit. At level 1 you have 6-8 ranks depending if you purchase 0, 1, or 2 ranks in that skill. You then add Insight to the total ranks.

When purchasing skill ranks it doesn't matter from which Vocational Kit those DP come, it matters if they are from the same Skill Category, and that no more than 2 ranks are purchased on the same skill.

1) Anytime a spell is cast, if the dice roll  is double sixes, then the GM checks for a Wyrstorm

This is a 1% chance, go higher, its a cool effect that will rarely appear this way, specially because there is a second check (A Tier 10 Spell has only .5% chance of causing a Wyrstorm)

Use:
A total of 6 on 2d10 for 5% chance.
Any doubles for 10% chance.
Any 6 in any of the d10 for near 20% chance.

Or you could use the second check directly, or use the spell check result against the Wyrstorm chances

I have also thought about different skills, talents, or rules for different mana sources with each source having its pros and cons, for ex

Inner Mana: the energy inside the character, it recovers by resting, the skill limit how much mana is available
Outer Mana: the energy on the nature, its almost limitless, but takes a lot of time to be gatherer, ritual skills go here.
Divine Mana: Its energy given by the Gods, the skill communion goes here

It could be called Against Dark Monsters
