The spell says the player may choose x quantity of creatures of y challenge rating. Nowhere does it say that the DM gets to pick what they are.

Yes, this should work for Druids with regards to recognizing the animal for Wild Shape. You have to conjure a Beast.

Also, this, read carefully:

Each beast is also considered fey

In addition to counting as a Beast, they also count as Fey.

Almost four years late, but to answer your question, technically no, as the summoned creatures count as Fey.

When you cast a spell like conjure woodland beings , does the spellcaster or the DM choose the creatures that are conjured?

A number of spells in the game let you summon creatures. Conjure animals, conjure celestial, conjure minor elementals, and conjure woodland beings are just a few examples.

Some spells of this sort specify that the spellcaster chooses the creature conjured. For example, find familiar gives the caster a list of animals to choose from.

Other spells of this sort let the spellcaster choose from among several broad options. For example, conjure minor elementals offers four options. Here are the first two:

• One elemental of challenge rating 2 or lower
• Two elementals of challenge rating 1 or lower

The design intent for options like these is that the spellcaster chooses one of them, and then the DM decides what creatures appear that fit the chosen option. For example, if you pick the second option, the DM chooses the two elementals that have a challenge rating of 1 or lower.

A spellcaster can certainly express a preference for what creatures shows up, but it’s up to the DM to determine if they do. The DM will often choose creatures that are appropriate for the campaign and that will be fun to introduce in a scene.

so could you make 32 scorpions and do 32d8+ druid turn+ temp for circle of shepherd and do extra damage at level 5 or maybe 8d8 + all the other stuff 

Theoretically

Quote from Mr_Muckacks >>

Bear in mind fellows-you can use a 9th level spell slot to summon 32 puppies.

Enjoy.

 This was a delight.

But no. Instead if you have a very annpyed druid BBEG, have them summon 32 Stirges and see how long the party lasts with their blood draining every round.

At this point it is better to simply use swarm mechanics like swarm of insects. A nip here and a tuck there, and the Swarm of Mesquite Death is here, and ready to drain a countryside dry.

As a DM, This spell is OP for the level.  The level 5 druid of Shepart is summoning quetzalcoatlus or 8 raptors with group tactics.  Those raptors do more damage than a fireball every turn when they hit.  

DM is the one that choose the animal to be summon, you can let the dice deside for you if you like to make it random.

Wacky question, but i assume they dont deal magical damage even if they are magically summoned, right?

Quote from Darastrix_the_kobold >>

Use 5th level spell slot, challenge rating 1/4, summon sixteen wolves.

With pack tactics your sixteen wolves will obliterate everything that stands in your way.

(except people that know fireball)

 oh heck yeah!

 = Druid's delayed blast fireball

I play this as the player picks the CR rating, and the DM picks what shows up.

I believe technically the dm chooses, that being said, I would let my players choose for theming or character, but if they do it to summon in 8 velociraptors I am revoking their privilege. Unless we are playing a Jurassic Park themed adventure.

And since the GM provides the stats, they choose the creature.  This has been clarified as RAI by Sage Advice, and is correct.

 6th LvL Shepard Druid has a feature that gets around that (all summoned creatures attacks count as magical)

can't wait to summon 16 giant owls to peck the crap out of the next guard I see kick a cat

I am going to use this spell by summoning 8 velociraptors every time I use it, they have 13AC, 10HP, Pack tactics, multiattack, bite( +4 to hit, d6+2 damage) and claw(+4 to hit, 1d4+2)

thats also very insane (The wolf one), but, I am a circle of the moon druid, and I go deinonychus, so I'm just a big raptor and all the others follow me

I'm making swarms a CR1/3 and allowing my druid to summon them cause its cool. I'll let you know how it goes.
