Her Dark Echos (Q) is on the same cooldown as karthus' q max rank and it does less damage than karthus hitting a single target with it and slightly more if karthus hits multiple targets. It also has 25 less range than karthus' q. It's similar to Soraka's Q in that it makes the target take more damage (but Soraka's Q does it differently).

Yes you are correct on her Psionic Pulse (W). The duration of the fear is the same as if the target had two stacks of Echos on the Void on them.

Her Nightmare (E) doubles and refreshes the duration of any fear that is currently on the target, not just her own, so this includes fiddlestick's fear, nocturne's fear and hecarim's fear. In the duration of this extended fear, all the damage dealt by this ability is healed back by her target, to offset the very high damage and to make it so you can then Retrograde (R) that target to make it take even more damage.

Her Retrograde switches damage with healing and healing with damage. This means that if a target is meant to be healed for...say...100, they take that amount of damage instead, and if they take 100 damage, they are healed for that amount instead.

Sorry about the confusion I typed this up at 1am in the morning lol I wasn't thinking too well. In hindsight, I do think the range on her E is a bit too much so I will be reducing the range as well as clarifying everything else. Thank you for your extensive feedback btw! :)
