I think the assasin should use a shortsword in her left, and a reverse grip dagger in her right. The shortsword would be all of left, right and overgead attacks, dagger used for the stab. The stab does extra damage if hitting the enemy behind. She can parry light weapons, and her repost can be thrust with the dagger, which adds a very small poison effect. (We're talking 3-5 health drain, nothing major. Just there for annoyance and because assasin). Alternatively, instead of a poison her ripost could be a normal swing with the sword (fully charged) and if the ripodte hits she can do a quick second hit with the dagger (also fully charged). Another idea i had is instead of parrying, she could have feints. Any sword attack can be cancelled mid swing for a thrust with the dagger. The thrust would would always be the same direction for balance reasons (backwards attack). Crossbow pistol maybe 3 or 4 shots, around flintlock damage. Caltrops do 1 damage, but slightly slow enemies. If an enemy is moving on the caltrops they continue to take damage. (Basically 1 damage for every step on the caltop). Therefore if an enemy steps on them they can stand still until they dissapear and not take the damage (besides initial damage for stepping them). Her specail can be she goes cloaked. She still functions as normal while cloaked, however if she pulls a backwards thrust on an emey while in this state, it does massive damage. Any sort of attack breaks the cloak.
I got the dual weild and poison/feint from for honors "peacekeeper", but i think it has potential. Thoughts??
