All about an ebony lass with a scimitar, and definitely all about some domme types trying to steal me and my girls away
I planned to build without mythic, but have in mind what options I think would be best for them.
@Ilven - the biggest mechanical difference between Wizard, Sorcerer and Arcanist is how they handle their spellcasting.
Wizards have a big spellbook containing as many spells as they want. Every day they must prepare spells and can
only cast those spells. If a Wizard prepares a single Fireball spell, that is the only Fireball he can cast all day. But she could also use that slot to prepare any other spell like lightning, acid, buff spells, divination, etc. etc. The Wizard has fewer spells per day, but is much quicker to get access to high level, powerful spells.
Sorcerers instinctively know a certain number of spells, and can cast those spells at any time they want up to a max number of spells per day. If a Sorcerer knows Fireball and Buff Spell, she can cast Fireball
or Buff however she wishes until she runs out of spells per day. But Fireball and Buff are her only options, and she cannot cast anything else. The Sorcerer has more spells per day, but is slower to get high level spells.
An Arcanist is a hybrid of these systems. She has a spellbook and prepares spells like the Wizard, but she casts those spells as if she were a Sorcerer without needing to specifically prepare them. The Arcanist can prepare her spells from the big list of Fireball, Lightning, Buff Spell, Divination, etc etc, but once she prepares Fireball and Buff she can freely cast either of those until she runs out of spells per day. The Arcanist has less spells per day like the Wizard and is slower to get high level spells like the Sorcerer.
In terms of lore and character backgrounds
The Wizard studied how to use magic and attains power through research.
The Sorcerer was born with magic and instinctively uses it.
The Arcanist studied Magic itself, and learned how to use it while breaking/bending some of its rules.
There's lots of other differences, but that's the core one.
@LeaT - For Lea, a Sniper Rogue should work fine. There are other classes and archetypes that can do long-distance killing better, but typically at the cost of lower skills. One of the Rogue's defining traits is the large number of skill points and bonuses they get so they can be the sneaker, the lockpicker, the pickpocket, the acrobat, etc.
For Iseldra, Witchguard is good flavor-wise but isn't a super-effective archetype. The problem is that the most effective defense in Pathfinder is killing your opponent before they can hit you. I can build her as a tank/bodyguard though, if that's the role you want for her.
Also, would you want Iseldra to be more melee or more ranged? Ranger's get a fighting style that determines what weaponset they're best with. Archery, Sword and Board, Heavy Weapons, Two Weapon Fighting, etc?
