You can only gain it via a quest afaik.
As for my opinion, its a living fireball, its ok once you can summon two minions at once, then you can have a dremora lord out (or a permanent pet if your mastered) and fire off continuous exploding puppies with the other hand.
As for the damage, it does not appear to be fantastic. It is a cheap aoe, comparable to a plain fireball, but it dies quickly if its attacked and it does not explode if its killed. It will also explode after a short period even if it can't path to its target in time, so its a little hit/miss.
To make good use of it you need long range summons, preferably 2/2 perks, so you can sumon it next to the targets, and you need to keep those targets distracted so they don't turn to attack it.
Like most temporary summons, it works best if you can cast it into another room while stealthed, and stay stealthed. Then you can just spam away while they clear the room. Spamming two at once is doable too once you have the perk.
