This mod aims to improve the vanilla Wyverns mechanics with new creatures & abilities.

So far, it has several new features and mechanics such as:

diving mechanic,
can strafe while hovering sideways and backwards
roar ability,
barrel roll,
continuous fire breath attack or 11 other breath types
body/pose adjustments,
random body proportions for each wyvern. Every wyvern is different than others
sleep pose
new sounds
new attack and new ability/behavoir
9 new chibis
pet ability
Simulated tail movement... ish

They spawn next to vanilla Wyverns in Wyvern spawn containers.

Serpent wyverns - 4 body variants and can get one out of ~12 different breath attacks. The onse that already exist in the mod.
Elemental Serpent wyverns. 4 variants. They look like Serpent ones but only have default vanilla breath attacks. They dont spawn in wild. You can only convert them from vanilla/Serpent with Wyvern bench
Zombie. 3 variants.They dont spawn in wild. You can only convert them from vanilla/Serpent with Wyvern bench. They inherit the breath of the wyvern used for conversion.

-Wyrm- It doesnt spwan in wild and it will inherit the breath of the poison wyvern used for conversion.

Added new item: Wyvern Spear to help you tame wild Serpent Wyverns. You can either craft it in Wyvern Bench or get it as you get the wyvern chibis.
How to tame? Drain a wild Serpent wyvern's HP down to less than 20% -> Pin it to the ground using a chain bola and a ballista -> Throw the Wyvern Spear in it (dont poke it). See the video.
Added Conversion from Vanilla to Serpent wyvern option and other way around plus few more conversions. Check the video, second half.

Attack mappings: Check HUD pannel(poop button)

Vanilla bite attack stays the same. Same button
Vanilla breath attack is replaced with continuous breath attack. Same button ( the fire might damage structures and stay on the ground for a while so you can set an entire kingdom on fire). Just hold it as much as you have stamina.
Player/dino grab -> C for PC. It will grab them and attach to the mouth instead of the feet. It works both in air and on the ground
While on the ground, press X for PCto do a wing flap attack(the old vanilla Taunt attack. It will give you extra speed boost of 30% for 5 seconds)
While air and you are moving forward, press X for PCto do a barrel roll attack (It will give you extra speed boost of 30% for 5 seconds)
Shift +R for PC will do a Roar.
Grab and eat attack/ability. This one is special. LCTRL on PC. For this attack, it will grab a dino/player in its mouth either if its on walking or flying and it will consume them to get a health regen buff. Once it picked its victim, its over.
A special similar ability. If some dinos, tamed or wild are walking too close to them, and they are grumpy, they will grawl and consume them to get the same regen buff. So pay attention with your pets and keep them away from any wyvern.

Some other fetures:

* You can change the wyvern pose in Radial menu. Also while mounted on the wyverns.
* You can set them to rest/sleep to regenerate HP faster.
* There are some custom sounds depending on the dino if its female or male and also if the player is female or male. Interracting with them to Sleep/Wake up will be a bit more immersive.
* To get the Chibis&Wyvern Spear, you must kill Wild Serpent Wyverns with a Crossbow. Last hit that kills it matters, not the entire HP draining process. Now that is a challenge. Every time you get a random one. There are 9 in total for now.
* They can grab Flyers too
* They are faster than vanilla
