In my opinion, all the lvl 1 options could really use a base dmg effect as they're all very situational. Fatality is the only thing in her kit that gives her kill potential to go on and snowball, she is very team dependant in that case, maybe a bit too much, meaning in solo queue or playing without a full team would make her unfun to play. 1 thing I would change to make her still able to be a good hero is to maybe swap the talent "Land of the Dead" into her E ability with reduced amount of corpses and cooldown, move the curses into her trait and keep the corpse things in the trait as well. This would make her have more control over when she gets to pop off in fights but still having the snow ball effect that she is all about.
Also, armor reduction from players reaches a cap at -25 armor (exceptions are Chromie and Sgt. Hammer lvl 20 talents), Brittle Touch exceeds that amount by 5 armor.
Concerning fatality, i agree it look powerfull, but,long cooldown and big mana cost, a "not so big" aera of effect, making hard to autokill more than one hero (ennemy low life heroes should always spread if this talent is picked).
In addition, a lot of spells are actually able to kill a 15% life enemy.
And you you say, this spell is a "all or nothing" one, that fact balance its power.
I like it like that, but im not a pro of balance...
I didnt wanted curses to make damages because her two other spells allready deals a lot.
Your right about armor reduction, should 5 stacks cap.
