The person who is DMing our Tyranny of Dragons campaign (HotDQ->RoT) is considering allowing my evil character to track down a Wyvern nest and find an egg to obtain a tamed mount using a significant chunk of my accumulated downtime. I made the case that this was fair, because in exchange I'm giving up a scarce resource that potentially allows you to craft powerful magic items (downtime days). Thanks to the DMG that just came out, there are now more extensive poison rules detailing the effects of Wyvern poison applied to a weapon and which may even allow me to harvest said poison from my mount.
The problem is, as written, the rules require the poisonous creature in question (in this case, my potential future Wyvern) to be either dead or incapacitated for up to six minutes as per DMG 258. I would like to be able to harvest poison without harming the creature (i.e., without doing any damage to it). Can this be accomplished? I am playing a Dragonborn Warlock with the Fiend patron and the Blade pact. Is there a Warlock spell capable of harmlessly incapacitating a target? I'm pretty sure Incapacitated is a very distinct condition, so not necessarily the same as Charmed or Paralyzed; therefore I'm unsure if Charm Monster or Hold Monster and their ilk are sufficient.

As far as I am aware, there is no way to give a creature the incapacitated condition directly. However, there are 4 conditions that give a creature the incapacitated condition as part of their effects. These are:
There are a number of ways to apply these conditions without damaging your beloved pet. Within the Warlock spell list, the ones I could find are:
However, only Flesh to Stone, Imprisonment and Power Word Stun last longer than 1 minute. Flesh to Stone is severely not recommended, since you really shouldn't be able to harvest posion from a statue. Imprisonment is expensive, but will work well for this task. Power Word Stun is probably the best option, since your creature can choose to fail its saving throws till you're finished.
On the other hand, if you have an allied Bard, Cleric, or Wizard, the 3rd-level spell Feign Death suits your needs perfectly. It will give a willing creature the incapacitated condition for an hour. A Cleric wouldn't even need to waste a spell learning it, since Clerics know all their spells automatically. Since it's a ritual, he wouldn't even need to waste a spell slot on casting it! All you have to do is talk him into preparing it.
Of course, all this is moot if your DM is willing to allow you to extract poison simply on the basis that your wyvern is tame and willing to allow you to do what you want to it. Given that he's giving you a CR 6 creature for a mount, a little bit of poison is really not a big deal.
