I am considering a dragonmarked halfling, artificer 20 (?), caster, focusing on the new SLAs + spells, for my casual playing on Wayfinder. (No EE ambitions whatsoever.)
Big investment into Arcanotechnician tree.
Moderate investment into halfling tree for dragonmarks, saves, perhaps heroic companion => dog.
Moderate investment into Battle Engineer.
No other trees available.
9/12 SF/GSF Evocation
12A augment summoning

18 Int (16)
16 Con (10)
16 Dex (6)
(Or perhaps less con/dex and bump str/cha)
