# How strong is the tressym in comparison to other familiar options? [closed]

I was looking at the tressym's description in the Storm King's Thunder adventure, and saw this (p. 243):

With the DM's permission, a person who casts the find familiar spell can choose to conjure a tressym instead of a normal cat.

The tressym seems really strong in comparison to other familiars, such as the owl (who many see as the strongest familiar).

Tressym as compared to the owl: $$\begin{array}{r|ccc} \text{} & \text{Tressym} & \text{Owl} \\ \hline \text{Stats} & \text{-4, +2, 0, 0, +1, +1} & \text{-4, +1, -1, -4, +1, -2} \\ \text{Skills} & \text{perception +5, stealth +4} & \text{perception +3, stealth +3} \\ \text{HP} & \text{HP(5)} & \text{HP(1)} \\ \text{AC} & \text{AC(12)} & \text{AC(11)} \\ \end{array}$$

The owl has a flying speed, but it has has almost no ground / climbing speed.
The tressym has the Detect Invisibility trait (with a range of 60 feet) as well as immunity to and detection of poison. These features compared to the Flyby ability of a owl seem not worth it to me.

Is it actually as strong as I think, or am I overlooking something?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

• This question is very likely going to get closed for being opinion based. It's certainly very versatile, but does that make it stronger? You'll have more success if you state in what area you want to compare them, then "stronger" is an objective thing, instead of a subjective one. – Theik Dec 11 '18 at 14:07
