Magnitude only works on spells that do damage based on the 5 Archmagics: Fire, Ice, Lighting, Dark and Holy. Although Miasma is a Dark based skill, it doesn't do Dark damage, only Poison, so this augment doesn't effect it whatsoever.

Morbidity doesn't increase spell damage at all, it increases damage enemies receive when debilitated by something not of the 5 archmagics by 30%. To explain, if a monster is Blinded/Silenced/Poisoned/etc. If you have Morbidity slotted, all your attacks will do 30% more damage to that monster until it's debilitation wears off. Unfortunately this doesn't work if the debilitation was caused by a spell, so again it doesn't effect this skill.

Toxicity works with this skill quite well though.
