Medic's melee
Can inject himself once.
40% movement speed nerf coupled with 150% damage resistance for 6 seconds.
Activating uber before the effect's diminish saves the medic. Otherwise, after 6 seconds, the medic is dealt with 600 damage. Or it could be 5 seconds long continuous damage totalling 600, as long as tanking the 120 damage per second. Activating 40 seconds worth of charge would be concise with the idea. Activating any kind of uber but the ones that require less amount of time and effort should be qualified.

During the effect, the jump is limited to one at time, and total of 2 in 10 seconds.

Another - Scout's movement speed drink
Drinking this soda restores scout's health to max.
Gives the scout 200% movement speed for 10 seconds.
During this, scout is not able to heal from medikits.
Scout is damaged over time, resulting in 60 total damage.
To activate this, Scout is required to kill 2 enemies at point blank.
The weapon of the method does not matter. Melee can contribute to the count. As long as the finishing attack is from a point blank distance.

The duration for the uber is administrated separately.

Field doctor
When the patient dies, it gives the doctor a charge for an uber.
3 segmented uber. When the uber is applied, it allows for multiple players to be healed.
The uber can be stacked, meaning the medic can heal up to 4 players at once.
The died players under the medic's extra beam also gives the medic one more uber charge.
The uber lasts 4 seconds.

Derringer - Spy's
When firing this weapon, it swaps the HP and Cloak meter in % metric.
When the HP is 50 and the cloak meter at 100%, firing this weapon makes the spy's HP 125 as it is max. And the cloak meter should be 40% because of the 50/125 situation.
The derringer's damage is 70. It stores 2 rounds only.
A weapon related compensation should be made. Paring this with specific weapons should give an adjusted stat and effects.

Vampire - Medic's melee
Simply sucks HP to convert to medic's.
Every 1.5 damage should be turned into 1hp for the medic.
30% damage reduction.

Kind of a joke weapon Complicated and not very intuitive (this is the weapon name) - Demoman' launcher
Dragon Dragon something jokes

Fires all 8 rounds in one click, a really quick barrage is fired. Dispersing accuracy.
When the pipe is exploded, the location is casted with a small circle of both team colors.
The circuit lasts 15 seconds long. When inside the circle of your team color, you get crits negation and 30% damage resistance. While you are inside the enemy team color, you get 30% damage vulnerability against all attacks. These effects are applied to the players of the both teams.
Only being able to be fired only when all 8 rounds are loaded. The weapon fires the projectiles of both team colors in 50% chance. Or 4:4. Only the projectiles of the player's team color damage the enemy. The projectile of enemy team color doesn't deal damage against anyone except the demo himself.
The circle itself is of a size only 1 or 2 man can stand inside.

Tide of the waving shadows
Cloak watch that allows the spy to turn invisible almost instantly.
When invisible, the spy is completely invincible, not even affected by airblasts and knockbacks.
While being cloaked, the current health of the spy becomes the max hp. Preventing the spy from taking medkits while invisible practically. When decloaked, the max hp slowly starts regaining.
Getting attacked while invincible reduces the remaining cloak meter, but it doesn't reveal the location of the spy there. The enemies that you bumped becomes transparent against enemy's sight. So that if a teammate disappeared suddenly, the guy is probably colliding with the enemy spy. This could be temporal, but might be good with 5 seconds extra duration. While in this state, the spy is able to stay invisible for 2 seconds. But the charge is filled up after 2 seconds. When you bump the enemies, the charge is filled instantly to the max. Becoming visible again is completely silent, and the spy can't decloak at will. The spy plays a shortened version of inspecting animation before being able to attack right after decloaking. Or it will simply swap weapons forcibly back to the knife, when the spy had a knife to begin with. Though almost instantly cloaking and decloaking, the visual effect is that the team color of translucent spy is replaced with pitch black. So It would be visually a complete dark human figure before the spy's figure turns into the normal vibrant color. This "Bumping into someone to retain the cloak" could be made active for teammates, so that spy can get closer to the enemy first hand without being spotted. Spy has a collision during this state of invisibility. The teammate can be phased through like a regular play, the enemy is felt solid like in the normal gameplay too. The enemy will likely notice that someone bumped the player. It's likely better to prevent the spy from becoming a shield. The damage that should have dealt to the spy should be applied to the pseudo "Host", but it might be dealing damage twice to the host. Simply making him not accept any hit registrations during the spy is having a direct contact with the teammate, this is it. All of this is only when the cloak is applied. Spy blocking people's path would be a problem, it's such a nuisance. The spy should be not prioritized for pushing people off. The enemy players should be able to push the spy to any directions with less force. But it reduces the feedback of collision with the spy, so it would make it harder to notice the slightest bump with the spy. Actually it might be better changing the spy's invincibility to a really hard shell. Otherwise it would be too easy to re gain the meter after getting attacked, though it's 2 seconds. Actually there was an idea of cloak watch that allows the user to pass through the enemy collision already, in this thread, by someone that's not me. So If it's okay, I'd make this capable of phasing through enemies, and make a distinct screen effect of slightly darker vignette added. Adding the sound of sort. All of this should come down to "I know there is a spy that's attached to me." But not being able to communicate with teammates about that is likely, so I'll make it visible to others that the spy is colliding. By making the colliding targets transparent against its friends.
