Once Conjure Animal ends, do all animal body parts disappear?

I was reading about poisons when I stumbled upon the “Serpent Venom”. In short, you can harvest the poison of a Giant Poisonous Snake and then use it on weapons / poison edibles. I was wondering, if I use Conjure Animals to spawn eight Giant Poisonous Snakes can I harvest their poison and store it or will it disappear once the spell ends?

The spell description states that:

Each beast is also considered fey, and it disappears when it drops to 0 hit points or when the spell ends.

I would guess that means all parts of the animal will disappear but I would like some clarification before making any plans.

Calculating HP for UA beast master animal companion

I am a very new DM in DnD 5e, and one of my players is a ranger. As I was browsing through posts here and there we decided to use the UA, as everyone is saying the RAW ranger is lackluster. She obtained her wolf in a little side story, and I would like to set up the stats for her companion. I read through the UA, and it states:

For each level you gain after 3rd, your animal
companion gains an additional hit die and increases its hit points accordingly.

Now this confuses me a lot, and upon further looking into how HP is calculated, I don’t even understand the stats of the simple Wolf enemy.

So in the Monster Manual the HP of the wolf is 11 (2d8+2).

First question: How is this calculated? The average of 2d8 should be 10. 10+2 is 12.

Second question: What is the hit die of a wolf? If its 1d8, than in case the wolf is “level 1”, its HP should be 10 (max hit die + con modifier). If it is considered to be level 2, its HP should be 17 (Max hit die + avg hit die + con modifier). What am I missing?

Third question: I found a post on a DnD reddit site where someone calculates the stats of a wolf in case the ranger is level 7. It goes like this:

Wolf

Medium beast, your alignment

Armor Class 17

Hit Points 35 (6d8+6)

Speed 40 ft.

STR 12 (+1)

DEX 17 (+3)

CON 12 (+1)

INT 3 (-4)

WIS 12 (+1)

CHA 6 (-2)

Proficiency Bonus +3

Skills: Perception +4, Stealth +6, Skill of Choice, Skill of Choice

Saving Throws: Str +4, Dex +6, Con +4, Int -1, Wis +4, Cha +1

Senses: passive Perception 14

Actions Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 11 (2d4 + 6) piercing damage. If the target is a creature, it must succeed on a DC 12 Strength saving throw or be knocked prone.

I think I was able to figure out everything, except the HP.

My first assumption was to start with the given base 11 HP as a level 3 companion. Than at level 4, it gains an additional 7 (5 hit die +con modifier). And the same thing goes on for level 5, 6 and 7, to a total of 11+4*7 totaling 39.

If I start from the 2d8+2, and just add a hit die each time the ranger levels up, I can understand the 6d8 mentioned in the post, but I don’t get the +6 modifier. Shouldn’t it be +10? +2 base modifier at level 3, and +2 for each 4 levels totaling at +10. And now the problem is that averaging this value leads to 40, not 39, this problem is coming from my first question.

I am completely lost here.

One last question. The Bite attack says +6 to hit. I can explain this as the DEX modifier became +3, and the proficiency bonus also became +3, however I dont understand the reason why DEX modifier is used for the Bite attack instead of STR.

Thanks a lot for the answer!

How much times the strength modifier does a chained barbarian add when making a bite using Animal Fury?

The assumption is bite is the only attack the barbarian makes during the turn, and the barbarian has no other natural attacks. I seem to get three different answers on this:

The barbarian adds 0.5x the strength modifier. This is because the rules on Animal Fury state that “If the bite hits, it deals 1d4 points of damage (assuming the barbarian is Medium; 1d3 points of damage if Small) plus half the barbarian’s Strength modifier.”

The barbarian adds 1x the strength modifier. This is because the 19 STR cannibal from the gamemastery guide has its bite damage listed as 1d4+4, which is consistent with this.

The barbarian adds 1.5x the strength modifier. This is because a bite is a primary natural attack, and the natural attack rules state that “If a creature has only one natural attack, it is always made using the creature’s full base attack bonus and adds 1-1/2 times the creature’s Strength bonus on damage rolls.”

So which one is it?

Can Forest Gnomes secretly converse (like Thieves Cant) with other Forest Gnomes/Firbolg/Speak with Animal Users via Speak with Small Beasts?

My party has two Forest Gnomes and a Firbolg and they want to use their racial features to secretly communicate.

Forest Gnomes have

Speak with Small Beasts: Through sound and gestures, you may communicate simple ideas with Small or smaller beasts.

Firbolg’s have:

Speech of Beast and Leaf: You have the ability to communicate in a limited manner with beasts and plants. They can understand the meaning of your words, though you have no special ability to understand them in return. You have advantage on all Charisma checks made to influence them.

Speak with Animals reads:

You gain the ability to comprehend and verbally communicate with beasts for the duration. The knowledge and awareness of many beasts is limited by their intelligence, but at minimum, beasts can give you information about nearby locations and monsters, including whatever they can perceive or have perceived within the past day. You might be able to persuade a beast to perform a small favor for you, at the GM’s discretion.

  1. Through their shared knowledge of Speak with Small Beasts can Forest Gnomes communicate simple ideas to each other?
  2. Can Forest Gnomes understand a Firbolg speaking to them as it would a small animal even though it could not respond in turn.
  3. Would a Speak With Animals user be able to eavesdrop on either?

How many times does a Mature Animal Companion attack per encounter without orders?

The Mature Animal Companion feat for Rangers (CRB p173) is really ambigious:

If you have the Hunt Prey action, your animal companion assaults the prey even without your orders. During an encounter, even if you don’t use the Command an Animal action, your animal companion can still use 1 action that round on your turn to Stride toward or Strike your prey.
(emphasis mine)

It makes a lot more sense with use instead of have, otherwise I might not even have a Prey for it to Strike.
But in that case, next round, when the Prey is still alive, will my Animal Companion just stand around?

Animal companion: roll additional HDs or not?

When a druid reaches level 3, his animal companion earns two hit dice. Do I have to roll them to give him more hp or is it only a number to use, for example, for spell effects? The manual also says that they “gain a Constitution modifier”, so I would roll them, but a level 3 animal companion might have more hp than the druid itself, which seems a bit overpowered to me.

At third-level, are rangers allowed to select a drake as their animal companion?

I wasn’t able to find anything about this in 5th Edition. A drake seems that it would exceed the 1/4 challenge rating stated in the PHB.

In this specific campaign, our Dungeon Master allows anything that is accessible on D&D Beyond not including Homebrew content.

I did find the Drake Warden Ranger archetype, which I assume is for Pathfinder, and thought it might be possible that I’d overlooked a similar variant in D&D 5E.
