Wyvernfell

Wyvernfell is a parameter determining how much damage your attacks deal to the Wyvernsoul Gauge of the monster. So how does it work precisely?

Disclaimer, during my testing, it became clear that the progression in the gauge is not linear. The middle of a square is worth more than its extremities, making it obviously basically impossible to get precise numeric values.

Wyvernsoul Gauge

The Wyvernsoul Gauge is located under the monster health bar. Your attacks depletes the gauge and when it’s totally emptied, the monster falls to the ground, getting Toppled. You’re then allowed to choose between performing a Synchronized Rush who will deal a certain amount of damage while filling your Kinship Gauge or leaving the monster Toppled on the ground, guaranteeing you critical hits for the incoming turn.

Some monsters have multiple Wyvernsoul Gauges to get through, most notably Elder Dragons. Breaking a Gauge will put them in the Vulnerable state, pushing them to use more Head-to-Head for a few turns.

Some monsters also use their own Wyvernsoul Gauges in a special way like Arkveld at the beginning of the fight or Deviljho when starved who won’t take any Wyvernsoul damage, recharging their Gauge instead before allowing you to damage it again.

Wyvernfell

Two parameters mainly determine how much Wyvernsoul damage your Monstie do:

the move Wyvernfell value
your Monstie own Wyvernfell value

These are pretty easy to understand: the higher the value, the more damage you will deal to the Wyvernsoul Gauge.

The Monstie base Wyvernfell value is linked to the species and is between 36 and 60, with the Bingo Amount Bonuses sometimes being able to add between 5 to 15 to the value.

For the moves, only Active Skills deal Wyvernfell damage, regular attacks dealing 0. The Wyvernfell values go between 10 and 70. The two strongest moves are Gale Trap from Sand Barrioth and Fruit Frenzy from Bishaten. But keep in mind that random multi-hits attacks like Fruit Frenzy will miss some of their hits making this in truth a potential 70, not a guaranteed.

Increasing Wyvernsoul Damage

Active Skills

There’s only 2 buffs/debuffs impacting Wyvernfell damage:

Wyvernfell Up
Wyvernsoul Defense Down

Aside from that, nothing except critical hits affects Wyvernfell.

Building the perfect Wyvernfell Monstie

Going through the game Monsties, it becomes possible to build a pretty solid Wyvernfell specialized Monstie.

For the species, the Monstie with the strongest Wyvernfell value is Paolumu, starting with a solid 60. It also has a Kinship Attack with 120 Wyvernfell who totally fits for the concept of the build. Looking more closely, the second best candidate is Yian Garuga. Despite only having 44 Wyvernfell, it also has a 5 bingo bonus of 15 Wyvernfell, raising its potential to 59. It also has a base 10% Crit Rate, giving it some chance to do 1.5 Wyvernfell damage sometimes.

For Active Skills, Pickaxe Beak is definitely the best for this build. Coming from Yian Garuga, it has a 40 Wyvernfell value for a weak 15 stamina cost, making it already pretty solid. But its main strength is the fact that it stacks the Wyvernsoul Defense Down debuff, increasing your Wyvernfell damage every time you use it. Due to the fact that your main attack is dragon, giving your Monstie a dual dragon element can be good to improve its regular damage.

Other Active Skills that work well with this build are Dracophage Shot, giving you a Tech answer and easier Bingos, or Gale Trap who has the strongest Wyvernfell value in the game and will deal great damage to the Wyvernsoul Gauge once the debuff has been stacked enough. Just keep in mind to renew the debuff before it expires. You can also consider buffing skills like Egg Skill: Icebreaker or Blade Rush.

For Passive Skills, you want to get Dragon Buster (XL) first for obvious reason. Some great genes to use after this are:

All-Out (XL): +40% damage to your skills but at the cost of +20% stamina cost (which isn’t that much since your skills cost 15 and 20 stamina)
Critical (XL): 15% Crit Rate so 15% chance to deal 1,5 Wyvernfell damage
Dragon Atk Boost (XL): +30% damage for Pickaxe Beak (and Dracophage Shot)
Elemental Assault (XL): if against something weak to dragon
Stamina Surge (XL): the stamina regen helps if you use All-Out
Soul Kinship (XL): faster riding, allowing you to use your powerful Kinship Attack sooner

You can use Kora as a support. Aside from her defensive abilities, her Gravios Bishaten Embers grants 3 more turns to debuffs, allowing you to increase the duration of Wyvernsoul Defense Down.
