Question about CF

Hi I just recently started playing with a bow and im confused about how crossfire works, It says that there are 5 levels of charging but how am I supposed to know what level my CF is charged to?

 

You either to have to manually count the seconds yourself, or just use your feeling.
And, oh, when your charge is at 5 or when you got hit by the enemy, the glow which is usually yellow is turned to red.

 

Just wait it and count
If you see the glow is red without getting hit,your handcannon is ready.
If you get hit while charging,the glow will turn red automatically and the dmg depend on how long you managed to keep it on.
Also there is an instance where you want to release cf but instead your char have question mark on head and no cf released (I think this happen if you charge then immediately tries to release it)

 

Go to the settings>graphics>support skill icon
Turn on the buff count so you'll know the level of charge is

 

ty all for the info
