Bleed Formation
The bleed synergy is based around Sinara’s 4-star skill. This synergy is the only synergy that can’t work with other synergies (weakness and female) as her 4-star silences commanders’ active skill.
Let’s have a quick look at how this synergy works before looking at a typical formation and analysing it. The bleed synergy works around the troop normal attacks :

All lineups deal normal attacks every second and Sinara’s war skill grants melee troops (cavalry, infantry, and spearmen) a 70% chance of performing 1 more additional normal attack (20% chance of striking twice during the battlefield) in the same second.
In a battlefield this is how it looks like: most of the time the extra normal attack is dealt in the same second.

Now we will look at how the synergy works when we have 5 commanders that all work to increase the damage dealt by the normal attacks of the commanders:

The report here doesn’t have Night King but he is a very good commander for this formation.
So this synergy works as bellow:
Sinara: her skill silences all allied commanders, preventing them from using their Active Army Skills. In exchange for this silence, Sinara’s Fearless Advancement grants melee troops a 70% chance of performing an additional attack (normal attacks) and a 20% chance of striking twice during the battlefield

Jon Snow: Jon Snow grants at the start of the battle a reduction of enemy normal attack damage by 15% for 15 seconds and he also grants a 20% chance for allied troops to deal a 150% critical hit. And this second skill lasts for 25 second.
Here bellow we have from the first second the JS skill that procs

And furthermore in the battle this is his critical hit:

Dearon: After 50 normal attacks, he deals damage to all enemies with damage coefficient of 50%. And if the enemy is inflicted by ‘Bleed’, they take an additional hit with 150% damage coefficient.
Bellow here we can see that he deals damage to all lineups and that the damage is increased because all lineups are affected by the bleed.

Rhea: Rhea’s 4 star skill is split in 2 main parts. The first one consists in her inflicting a bleed after allied troops have landed a critic damage. And in the second part, after a total of 20 normal attacks dealt by the front row, the next normal attack of the troops is transformed into a critic hit which deals a damage equivalent to 120%.
Here bellow you can see how her skill pops in a battlefield:


Vorian: his skill can be broken down into three key components:
-
All columns under Vorian's command inflict bleed damage on the enemy for 5 seconds, triggered every 3 normal attacks.
-
The column led directly by Vorian benefits from an additional 40% chance to inflict critical damage of 180%
-
Each time an allied lineup lands a critical hit, they gain a reflection effect, which can stack up to 5 times. This reflection returns 50% of the damage dealt by the attackers.
Here bellow we can see from the first second of the battlefield, 2 on 3 of vorian skills proc which grants a great advantage to the troops lead by him.

The other skill as written procs after 3 normal attacks and a 5 second in the battle:

Here we can see how the reflection effect is show in a battlefield and It allows to reduce damage taken by allies from enemies.

Other useful commanders in the bleed synergy:
Lareo: Lareo procs every 4 normal attack where he increases the ally lineups’ health by 5% and grants a 50% chance to get a crit attack in the next normal attack that deals damage coefficient to 120%

Kevin: Kevin has 15% chance (30% when it comes to inf, cav and spear troop type) to grant a shield to the lineup with the biggest loss and it reduces by 10% all non-skill damage for 2 second and this can go to 50%. He is one of the best mid pay to win commander when it comes to countering weakness in this bleed formation.

Julien: Every time commander Julien’s lineup launches an attack, the lineup damage is increased by 2% and that can stack to 16 % like in the report bellow:

Barret: Barret skill procs after 8 normal attacks dealt by allies and it consists in him having a 50% chance of inflicting a bleed on the enemy lineup, so he will deal the equivalent of 20% extra of troops attack every 5 second of the game

Now let’s talk about dragon skills that boost the bleed synergy:
Dragon Bleed Skill:
This skill is a must in every bleed formation as it increases the allied bleed damage by 10% which can lead to dealing huge damage to the enemy during the battlefield.

Dragon flame skill:
Another essential skill in the bleed combo, this skill is increased by Sinara’s 4 star-skill and it consists in having a 40% chance of the dragon launching an attack of a 180% coefficient of damage after 10 normal attacks. This skill can proc up to 10 times in a battel.

Castle Skins:
For bleed we have 3 different castle skin:
These 3 castle skins grant each an increase of the bleed damage by 25% and added to that, the Castle of Triumph increases the normal attack by 5% and the bleed damage again by 5% making it a 30% increase in bleed damage and 5% in normal attacks. These bonuses don’t stack and only the castle skin who’s attributes are activated will have his bonus on.
