## Guidelines

Call for Fire is one of the Most Difficult abilities in the game to use, given that it has multiple parameters that you must type into the chat bar to alter it's effects. Here are some rough suggestions to guide you:

1. Directional: "-d ###": If you are dropping multiple shells, controls the angle they will fall towards after the initial point. An angle on the unit circle. (i.e. -d 90 (Alignment of shells facing North), -d 360 or 0 (East), -d 270 (South), -d 180 (West). There is also a "-d c" meaning circular, but it is less accurate than using -d 0 when using a single shell, so only use "-d c" when you are too lazy to use directional shelling or need to drop shells quickly.
2. Shell Count: "-s #": Determines the number of shells you will drop with your next CFF. Ranges from 1-5.
3. Interval: "-i #.####": If you are dropping multiple shells, this determines how long apart in time they will drop. Ranges from 0.2-5 seconds.
4. Radius: "-r #": If you are dropping multiple shells, this determines how far apart in space they will drop. Ranges from 2-5 tiles.

Some general tips:

1. Shell Movement speed is Radius / Interval (i.e. tile/shell \* 1/(seconds/shell). You would ideally want to match your shell movement speed to the speed of your enemies. For 99.99% of cases, you only need interval to do this, since a low radius of 2 with a quick drop of 0.2 seconds allows you to theoretically hit an enemy that moves at 10 ms, and a low radius of 2 with an interval of 5 allows you to hit enemies that are so slow, that they haven't implemented them yet! **So get good at using and knowing interval, and you won't need radius.**
2. You will want to be kiting as FSS unless your kiter is in comms and knows you are shelling.
3. The first shell drops on your mark 5 seconds after cast time, meaning you will have to lead the shot and not kill yourself at the same time.
4. If you are curious about the damage distribution, here is a snippet from the game's source:
```
 <AreaArray Radius="1" Fraction="1"/>
 <AreaArray Radius="2" Fraction="0.6"/>
 <AreaArray Radius="4" Fraction="0.4"/>

```
