the explosive ammo for cannons?

[Samantha Wildhound]

I dont like fury much (and NO expert by any means, i can barely hit a war galleon im so blind)
But maxxed with both, and lightning still does a better job, farther range, and more damage per hit,

however fury does have good points, its a good last ditch weapon if youre out of lightning, or the ships get too close, as for every 1 shot of lightning, you can shoot 3 furies, be aware it has the range of a basic cannonball though give or take (to me anyways)

I wouldnt get them again, but thats just me, as I have been able to take out every ship in the game with lightning, and I have a hard time with doing it with fury. (maybe i just cant aim! )
