Spotlights

New Features
Perks
Both trees have a total of 30 spendable perks currently.
Most perks from the Lupine Tree (the new one) benefit both forms (Humanoid and Werewolf).
Perks from the Hircine Tree (the old one) are focused on the beast form, though a few benefit both.
Later perks give you a small chance to increase your attributes when feeding, increased chance with higher player level and more werewolf perks unlocked. A more detailed explanation of all the perks can be found in the Perk Rundown Section.
Lupine Feeding
Lupines feed on the sorrows of the dead, this process deals damage to them, but is the only way for them to progress through their perk tree. This feeding or Purification allows them to obtain knowledge attached to said sorrows, later on allowing them to progress through their skills among other things.
New Howls
Upon selecting the tree you desire to progress along, you will be given an ability allowing you to choose the howls respective to that tree, the Hircine tree has the vanilla howls, with a few caveats added by some of the new perks. The Lupine tree features 3 new howls that influence the world around them. . The following are the howls added by the Lupine tree. 

Howl of the Tempest
Inflicts minor shock damage in a large area, with a small chance to paralyze targets in the area of effect.

Howl of Cursed Earth
Inflict Major damage to Stamina and Magicka in a large area, a later perk increases the damage done as well as applying a slow effect.

Howl of Prismagine Blur
Gives the user invisibility for a short period. A small chance that those in its area of influence will go into a frenzied state.

Equip the Choose Howl power and use it to select the howl you wish to use.

Archival Siphon
This is the biggest benefit one can gain from the Lupine Tree, this perk allows the player to gain skill increases when feeding. Comes in three levels, each level giving you an additional roll at a skill increase. The chance is determined by both the Players level and the amount of werewolf perks they have earned. Archival Siphon focuses on three skills of your choice when it chooses what skill to increase when you feed. You can choose the skills it selects with the Choose Archival Skills power added when you purchase the perk.

Unique Equipment
A later perk allows the user to create a special piece of equipment used by their werewolf form, offering a unique benefit. The equipment comes in a vanilla shape, La Femme Lycanna shape, and an invisible version if you do not like how they look. The armors are automatically equipped when you transform, after you have purchased the perk that allows you to craft them at a forge.

The Hircine Tree equipment offers your werewolf form 25% damage reflection.

The Lupine Tree equipment offers your werewolf form increased armor and either a bonus to health regeneration in the day, or a boost to howl recovery at night.

Attribute Boost
In the later perks, you have a chance to increase your attributes (Health, Stamina, and Magicka) when feeding. Chance is based upon character level and werewolf perks earned. The chance is much lower than that of Archival Siphon. You can purchase perks that increase the boost to the attributes, up to 5 in each. Another perks also increases carry weight when you gain attributes when feeding.

Digging as a Werewolf
When you are in werewolf form, you can now look at the ground and dig for items once every six hours. Item obtained vary in quality and rarity. Common items include Ores and Bones, but occasionally you may find Gemstones or Gear buried in the earth.
