So I saw stirges on the list of 1/8 cr woodland creatures on the spell conjure woodland creatures, and since the spell only limits things of 1/4 cr and higher, does this mean you can summon a swarm of stirges, either 16 of them to follow the pattern of doubling the amount as one goes down in cr, or just an nigh on unlimited number of the bastards. If I were a bad guy and even just 8 of these things appeared and started attaching themselves to my friends summon by some crazy druid out of the backwoods, I wouldn't run. Spiders and mosquitoes are bad enough. These things are huge and mean business. If I were a DM I'd be tempted to limit it to 16 instead of unlimited because that would be annoying to have to make my little minions have to run away, chased by giant bloodsucking insects like some horror movie.

The creature being attached to its victim doesn't modify any other mechanics. Players still have to roll to attack, and it doesn't have penalties on saving throws, nor do attackers receive advantage. Attacks that miss also do not necessarily hit the stirge's victim.

Anything beyond the exact language provided is the dungeon master's call to provide, interpret, or add to, as with all of 5th Edition.

The Chwinga Squidling familiar uses these stats and I’m frankly horrified at the possibilities…

Can a stirge do a second attack?  Meaning after an initial HIT followed by sucking in 10HP worth of the victims blood - the stirge detaches.  What happens to the stirge?  Can it attack again?  If I conjure this little creature, I don't want 10 HP damage to be my max for the duration they are in play.

FREAKY

The player can use their action to remove the stirge, attacking would still be against their ac. as the dm you can decide how you want to do it, but either way stirgest attack in groups, so their action economy is still being wasted on the attached stirge,

One of them bit me so I pet it and let it drink my blood, it did 2 dp and I tamed it, then I casted spells on it to make it able to face a dragon, and win

When i first saw this i thought it was kind of lame. Then i decided to run it against a level 2 party. It was nearly a party wipe. Lokey easily one of my favorite low level monsters now and a nice break from the goblins every dm i ever met seems to want to use for the first two levels

My understanding is yes.  A player, on their turn, can remove the Stirge with out having to roll. However, they do need to spend their action for that turn. 

Can a stirge attack again after it sucked out 10 HP or is it out of action? 

If it can attack again, can they attack the same creature or must it be another?

If out of action - for how long?  We all must eat again!

It's the size of a bat, so I would say that most birds of prey would probably hunt stirges. owls at night, hawks and the like during the day.

The Stirge cannot attack while attached to the target. It's proboscis remains inserted into the target drinking blood each time until there is no life in the victim, or, it is detached voluntarily or involuntarily. Dreadful creatures when they swarm a player. Its not a grapple either so the player is free to try to attack or do whatever they choose.

YOU MEAN WIRED 

my brother gave me P T S D with this thing

: ( 1 star would not recommend.

I really don't understand how this is considered a beast and a roc, which is literally a gigantic bird, isn't. 

I mean, it's like a horrible cross between a mosquito and a bat, with rotting wings and a size that would make a hellhound cry.

I remember back in 1E and 2E we had a stirge that was variant to it. It did the 1d4+1 damage. But after it got your blood and detached you would lose 1-3 hp per round for 2 rounds as the anticoagulant properties of the probiscus would let the wound keep bleeding. Really nasty, you could kill the little bastards but if enough of them hit you, you could die from potential post combat blood loss.

If a strige is attached and the player wants to use an action to remove them, does that mean they cannot attack the strige that turn? If so, that means it might make more sense to attack the strige rather than remove it. Also once the strige flies back up, does that make it vulnerable to an opportunity attack? And once the player detaches the strige, assuming they cannot attack it on the same turn as detaching it, does it just remain in the 5ft square next to the character or fly back up? Thanks

These are beasts? Guess this is going into the druid’s repertoire of wild shape forms.

 Right up there with flying snakes! Kinda makes me wanna play a dhampir druid...
