Don't worry, you're not doing anything wrong. I actually redid that quest last night on an alt and noticed the same thing - she used to recommend "Aetherflow and Energy Drain" (in the old system, you cast Aetherflow to gain charges for special skills, and Energy Drain used those charges). They've half-edited it but messed up the recommendation.

"Miasma and Bio" probably would be a good substitute with the spells currently available at that level. For bigger high-HP enemies in particular, make sure you're casting both those spells on it for damage over time. It doesn't matter so much for small enemies that die in a few hits.
