As many Sorcerers that use pets from the Daedric Summoning skill line know, these pets (Winged Twilight, Clannfear/Familiar) do not benefit from increased Spell Damage, but rather scale their damage only with Max Magicka. I wanted to do a more comprehensive analysis of all possible pet-enhancing buffs to better understand how to get the most out of my pets, but also to look for areas of inconsistency. I looked specifically at the Greater Storm Atronach, Twilight Matriarch, Volatile Familiar, Maw of the Infernal, and Warden Bear (Eternal Guardian). The following data was accumulated from isolated experiments on a target dummy. The format of this post will be: Findings Chart, Chart Explanation, Discussion and Suggestions, and Raw Data.
Findings Chart:

Chart Explanation:
- The rows represent each damage source.
- The columns represent each way a damage source could be buffed. In the case of Master at Arms vs Thaumaturge, only one of these would be possibly useful for any particular damage type (N/A is used to designate that this buff would not be possible for that damage type). The Additional CP category just refers to having more CP, but not necessarily on a node that directly buffs damage. This only applies up to 100 CP in the Blue tree, as this adds more Max Magicka until capping there. So if something benefits from Max Magicka, it will benefit from Additional CP.
- The distinction between the Familiar basic attacks and player-activated Damage Pulse is important, as you can see they do not behave the same. Also, an enemy NPC will recognize the Damage Pulse as damage "from the player" instead of from the pet, and can draw aggro toward the player.
- The Warden's Bear benefits from all possible buffs. It also attacks at the rate of once every 1 second rather than the other pets that attack once every 2 seconds. It doesn't have access to a buff like Daedric Prey, though (marked as N/A).
- Maw of the Infernal, being a monster set, cannot crit, so things like Crit Chance or Elfborn are irrelevant (and therefore marked as N/A). You'll notice, however, that Maw's Fiery Breath fails to gain the same penetration buffs as the melee attacks, which seems like a bug.
Discussion and Suggestions:
- There seems to be a consistent rationale about most of these buffs (at least when considering similar damage sources against each other), but again, it really seems like the lack of the Lover Stone or Spell Erosion to positively effect Maw of the Infernal's Fiery Breath, while at the same time positively effecting it's melee attacks, should be considered a bug.
- Now regarding the Basic Attacks of the Sorcerer pets, the fact that CP has no effect on them, especially when considering the Storm Atronach, seems very odd. Is this simply an oversight from when CP was initially implemented, I wonder? Also, it seems very strange that the pets borrow the player's Crit Chance (including the extra 12% from the Spell Precision node in the CP system), and yet they do not recognize Major/Minor Prophesy.
- Finally, if we look at the Warden Bear, it seems that the current thinking of the dev team is to allow all buffs to effect the pet: Spell damage, Magicka, player Penetration, Major/minor Sorcery/Prophesy/Breach, CP. If this is the case for the Bear, why not for the Sorcerer pets?
So my main suggestion would be to go through all pets (both from skills and sets) and unify them to behave like the Warden's Bear, where all buffs are applicable. Base values may then need to be adjusted accordingly, but the end result would be more understandable for players and would allow sets that buff Spell Damage to be equally useful to pet and non-pet Sorcs.
Raw Data:
The following is the recording of damage for non-crit and otherwise non-buffed attacks. The Non-combat CP numbers act as a new baseline to compare later values with CP.
