Nothing you don't want fury its a evil shot it will blind you and if you have a slow PC it will make it crash!

I only have 1 skill point in it i would never recommend maxing it or ever being nice to it.
If you want a strong cannon skill
max shoot,
round shot, barrage,
and rapid reload
it makes broadsides super strong (makes them stronger than maxing board sides but, maxing board sides for sailing also increases the damage )and when using round shot it never runs out of ammo
Fury can only carry a max of 125 shots which will run out in 2 1/2 minutes if your in major svs.
