-Blight feels like it might not be that big of a debuff. Missing 50% of your base HP isn't much of a problem on PvE since necromancer has access to some great sustainability options.
-Keeping this in mind, the elite elixir feels overpowered, the only penalty to 5 seconds of everything is about 20% of your HP being missing. I think the elixir of ambition needs an additional penalty or something to make it more of a risk/reward ability.
-The two elixirs which provide resistance and resolution are underwhelming.
