Gift of the Woods
Gift of the Woods is the second perk given to the Woods King. It grants the player with health regeneration (The exact same as 25% Adrenaline, or 1 health every second) and 25% increased body size, like the Faction Leaders.
 * Although it may recover health over time like adrenaline, it is not adrenaline.

Rare Potato
Rare Potato is a perk given by the K-pot-ato Helmet. With this perk, if a player destroys a potato, it increases the chance to give a good weapon by making the weapon swap to weapons with a quality value of 1. However, very rarely, you can get a single M9 out of it.

Mass Medicate
Mass Medicate is a perk given to the Medic. With the perk, the Medic can heal players surrounding the them. The possible healings are: This effect is triggered when the Medic is healing themselves, and if the Medic is using a Consumable, the consumable will show on the Medic as an emote.
 * Restore health (Red circle)
 * Increase adrenaline (Green circle)
 * Reviving Downed players (Purple circle)

Mass Medicate reduces the time for using a consumable (but not revives) by 20%.

Mass Medicate also allows for medics to use Med Kits and Bandages with full health.

Endless Ammo
Endless Ammo is a perk given by the Marksman Helmet. With this perk, the Player reload his gun without consuming Ammo, even Flare Guns.

Using

 * Leadership
 * Use the max Adrenaline to your advantage to move faster, which can be useful for hunting players down, strafing and running away when at low health.
 * The adrenaline also allows you to heal extremely fast without the need of any medical supplies. So most of the time, you can be easily healed with a bandage or two. However, it is still recommended to use a med kit whenever you have 35% health or below.
 * Firepower
 * Use the extra ammunition to add offensive pressure to your target. If they are hiding, gun down their cover with a gun and switch to your secondary to finish them. If they are hiding behind an indestructible object, throw a grenade at them.
 * The Firepower perk gives immense bonuses to close range weapons, like a 50 bullet MAC-10 and an 8 magazine Saiga-12. Use this extra ammo to quickly clear out small groups of enemies.
 * Windwalk
 * Windwalk is perfect for rushing and running away from enemies, as you can move at fast speeds even on water.
 * Gift of the Woods
 * The effects of this perk aren't significant. Consider it a slight stat buff.
 * Do not overestimate the health regeneration. Pills and Sodas are still recommended.
 * Think of it as a nerfed, portable Sauna that doesn't show particles
 * Rare Potato
 * If you find random weapons around, shoot them at potatoes. When you have 2 guns that you are satisfied with, use this perk to give your teammates good or better weapons.
 * Mass Medicate
 * Keep close to the teammates. When they need to heal, just click one of the consumables (full for you), and call the teammates to heal both them and yourself. It is also useful when attacking one of the Bridges in 50v50, as the medic can heal many players faster than adrenaline with just Bandages.
 * Endless Ammo
 * Use the Perk's advantage to fight with opponents with guns that requires special Ammo without running out of Ammo.
 * Keep reload your guns when not fighting to not waste time dodging the bullets while reloading.
 * If you are skillful enough, you can find a Flare Gun, spam Air Drops to bait players, and kill them.

Against

 * Leadership
 * The leader usually has a posse of 3-6 people around them, possibly more, so grenades are useful for eliminating the "bodyguards".
 * In this case, it is better to spam grenades to add pressure and take out more people.
 * When the leader became alone,keep crossfire.It will make leader on low HP.
 * Faction Leaders also have the Leader Helmet providing massive armoring, as well as an AN-94 or Super 90. To help against the armor, try high damage or high DPS weapons, like the SV-98 or the MAC-10. SMGs such as the MAC-10 and Vector are typically stronger than their weapons when close enough so try to use that to your advantage, however be aware that they may have a close range weapon too.
 * Their increased size makes them slightly easier to hit.
 * Firepower
 * Since they have more capacity than other weapons, use a Tree or Stone to shield yourself from the Lieutenant's ammo, and when they finally run out, attack.
 * You can also use an LMG to out-gun the Lieutenant, if you have one. The PKP Pecheneg and M249 is best for this strategy.
 * Windwalk
 * Since Windwalk leaves behind a trail of glowing leaves, follow them when the king tries to run away.
 * Don't shoot at the king until you are sure that several shots will connect to deal a sizeable portion of damage.
 * Use high adrenaline to catch up to the Woods King.
 * Using melee weapons to damage the Woods King is a risky but effective strategy, as those don't trigger Windwalk.
 * Gift of the Woods
 * The small health regeneration it gives isn't that important, and the increased size makes them slightly easier to hit.
 * Rare Potato
 * The only effect of this is that they end up with rare weapon combos, which happens anyways, so just fight as you usually would against them.
 * Mass Medicate
 * This perk can be difficult to fight if the Medic is spamming Bandages and adrenaline supplies for nearby players, which can attack you in turn. Go for the medic when there are fewer enemy players nearby.
 * Grenades, especially MIRV Grenades, are extremely effective against a group of enemies huddling around a medic.
 * Endless Ammo
 * This perk can be somewhat difficult to fight, especially in long battles, due to the Marksman will never run out of Ammo. Fight the Marksman as normal, but keep the fight as short as possible.
 * When the Marksman is hiding behind a ton of unopened Meteor Crates, flush him out with Throwables, especially Frag Grenades, MIRV Grenades, and Strobes.

Trivia

 * In the code, perks are just images, names, and descriptions, while the stats are actually decided by the role you have.
 * During the first woods event with the Shishigami no Kabuto, you could trigger the windwalk effect by being shot by a teammate.
