Tyreese's Circles

Tyreese's Circles is a powerful mechanic in the game, creating glowing circles on the map which slow all kinds of walkers down, including Commonwealth Walkers, who otherwise are immune to status effects. Unfortunately the circles are plagued by several bugs, so it is worth spending some time understanding the mechanics in order to avoid unexpected defeats.

## How Circles Normally Work

When Tyreese (or any melee survivor, if Tyreese is the team leader) uses a charge attack, a circle with a radius of 2 is created at the spot of the main attack. Here Jesus makes a charge attack and creates a circle:

The Circle is now fixed in this place:

* When Tyreese is the Team Leader, up to 4 circles can be placed on the map at the same time. The circles last 4 rounds. Note that there is no timer or other indicator showing when they will disappear. If Tyreese is a Team member, he can place up to 2 circles on the map.
* If the max number of circles is existing on the map, additional charge attacks will not create new circles.
* Overlapping circles have no additional benefits
* Any walker that walks into a circle must stop after 1 move
* Any walker already inside a circle can only make 1 move
* Any walker exiting a circle can only make 1 move
	+ This has been reported by some, but it is unclear if this really happens: (HOWEVER, a walker is allowed to entering a circle with its first move and exiting with its second move)
* Walkers starting their turn inside a circle will take will take damage (this includes CW walkers), with the amount increasing based on the level of Tyreese's LT. Note that the damage is "non-lethal" so walkers health will not decrease below 1 HP
	+ Note that fire damage is inflicted before the circle damage, so a walker with more than 10% health will always stay alive after having taken fire & circle damage
* The Lucky trait has no impact on anything regarding the circles
* Since the main function of the circles (slowing walkers down) is based on the basic function of the circles, it means Tyreese is a good hero from the get go.
* If Princess is the team leader, Tyreese can get charge points from walkers being injured from the circles.

## Bugged Behavior of the Circles

* **The bug with Tyreese's Circles has been fixed in update 6.3 and the section below is no longer relevant.**

### Walkers walking into each other

* The most commonly occuring bug with circles is that walkers will start piling up on each other. This is due to the mechanic of walkers having a movement range of 2. When a walker just outside a circle is in turn to move, it will look for a vacant tile 2 steps away, inside the circle. It will then start to pass through another walker to reach that target tile, but when it enters the circle it must stop, and ends its move on top of the other walker(s) already occupying the tile.
* In the picture below, the circled walker wants to move to the empty tile two steps left by first going diagonally down and left. Since it enters the circle it must stop on top of the stunned walker next to RGG, and since it ends its turn next to its indended target it will attack RGG.
	+ If the empty tile two steps left of the walker had been occupied, there would have been nowhere for the walker to go and it would have stayed in place.

* Another example of the same behavior. The two circled walkers want to move 2 steps forward, but each end up on top of other walkers as they need to stop when they enter the circle:

* If you reload the game in a situation where several walkers occupy the same cell, the extra walkers will be relocated to nearby vacant cells. This can sometimes cause new problems, as walkers can now suddenly appear in unexpected places.

### Walkers being overwatched getting extra movement

* A walker that is being attacked by an overwatch attack can sometimes make its full move, disregarding the circles
* In the example below, a fast walker is 3 steps away from Tyreese. As it is being overwatched, it is allowed its full move and ends up being stunned by Tyreese. Note additionally that it being crippled doesn't matter in this case. Video Link.

### Moving from one Circle to Another gives an extra move

* If the walker starts outside a circle, and there are overlapping circles, it is allowed to move through to the second circle using two movement points. Note that this depends on which circle is "on top" of the other. For example in the example picture higher above, the two circled walkers can not make two steps, even though it looks like they could be transitioning from one circle to the other.

### Walkers can attack through hard corners while inside a circle

* Once walker enters a circle, it can attack against hard corner. This is also true when the walker enter a circle then exit again.

### Attacking stacks of walkers

* If you attack a stack of walkers, all of them will be hit and damaged.
* If the stack is hit by a push weapon, the top walker will be pushed, but the others will remain in the tile.
* Note that if the stack contains special walkers, it could contain both stunned and unstunned walkers.
