Cat School:
Most Witchers of the Cat School are ruthless killers. Cat school witchers as well as their equipment do not deal a lot of raw damage, but can inflict deadly hits. They are propably proficient in kill hunmen. So I Increase armor resistance to hunman attacks and add chance for instant kill.

new 3 pieces bonus:  For each piece of the set, Strong Attacks will increase Fast Attack damage for 5 seconds by 12%, whether it deals damage or not.
new 6 pieces bonus:  Decrease fall damage. Running in combat no longer costs Stamina. Rear attacks deal 100% more damage, and instantly kill opponents at the cost of 1 Adrenaline Point(s).


Griffin School:
Witchers of the Griffin School are noble knights, they possess higher standards of social etiquette compared to other schools. Griffin School have specialized in the use of magic and is also the only school that specializes in horse warfare. So I improve its ability to fight on horse.

new 3 pieces bonus:  After using Stamina to cast a Sign in its standard mode, the next Sign cast within 3 seconds will be cast in standard mode without using Stamina. Each piece of the set will increase sword damage on horseback by 30%. 
new 6 pieces bonus:  The size of Yrden traps is increased by 40%. While you are within an Yrden trap, Stamina regeneration is increased by 5/s and Sign Intensity by 100%, and damage is reduced by 20%. Greatly increase resistance when riding.


Bear School:
Witchers of the Bear School, unlike the Wolves or Griffins, tend to be loners and do not forge strong bonds with their brethren. These Witchers rely on thier powerful individual abilities to deal with any problems. I don't like to see these warriors hidding in Quen.

3 pieces bonus:  When a Quen shield shatters, there is a chance a new one will be cast at no Stamina cost. The bonus increases by 5% for each piece of the set. 
new 6 pieces bonus:  Gain 0.2 Adrenaline Point when successfully parrying attacks, now swords can parry Strong Attacks of heavy weapons and most monsters. Strong Attack damage is increased by 50% with Heavy Knockdown effect at the cost of 2 Adrenaline Point(s).




Wolf School(Wolf and forgotten Wolf):
We are very familiar with Wolf School because our main character, Geralt of Rivia, is one of them. The Wolf school attaches great importance to  swordsmanship and emphasize the combination of it. But it is nearly impossible to be done because of the game mechanics. 

new 3 pieces bonus:  For each piece of the set, each percent Vitality lost increases Sword Damage by 0.2%, and each instance of Bleeding applied to enemies increases sword damage by 1%. 
new 6 pieces bonus:  Force to counter when parrying during enemies attack. Each Adrenaline Point increases the possible number of Bleeding effects that can be applied to a single enemy. Strong Attacks will make enemies blind and bleed at the cost of 1 Adrenaline Point.

As to Forgotten Wolf..... Although it's been many years, I think Wolf set and Forgotten Wolf set must have something in commom. After all, we are Wolves, right?

new 3 pieces bonus: Each piece of the set will decrease enemy damage affected by Yrden by 10%.
new 6 pieces bonus: Force to counter when parrying during enemies attack. To enemies affected by Yrden, Aard deals additional damage, and Strong Attacks will freeze enemies at the cost of 1 Adrenaline Point(s).


Viper School:（Improved from my previous mod）
I was really hoping official add an unique set bonus for Viper School in the NextGen update (they had time to make a new one for Wolf after all). But they don't.
Viper School was built for a noble aim—defeating Wild Hunt. Unfortunately, they degenerated due to the aim is unattainable,and they became murderers just like most Witchers from Cat School.  They're good with daggers(So I made it to light Armor) and like to poison their weapons.

new 3 pieces bonus:  When any sword oil is applied: Add Slowdown effect to melee attack. Each piece of the set will increase the critical hit chance of light attack by 10%. 
new 6 pieces bonus:  When the corresponding sword oil is applied: Inflict an extra permanent Poisoning effect on enemies. Enemies parrying attacks will also be poisoned. Increase instant kill chance by 7% to slowed or poisoned enemies.

Manticore School:（Improved from my previous mod）
Witchers of the Manticore School are accustomed to facing beasts with heavy armour and lots of poison, so they developed high patience to fight against the foreign monsters' poison and the toxicity in their own potions. They also have some expertise in alchemy and are used to carrying a lot of potions and bombs.
(Actually, Manticore School are different from other Witcher school.They are all equipped with specially made shield,more like guards. But I fail to achieve this.)

new 3 pieces bonus: When Toxicity exceeds the safe threshold, Vitality won't be lost. Each piece of the set will increase the duration of potions by 10 seconds. 
new 6 pieces bonus: Critical hit chances and critical hit damage also apply to bombs. Bombs are thrown without any delay, and critical hit chances of bombs are increased by 50%. The maximum number of charges for bombs is increased by 4.
