Grenades

[MacIronhawk]

There's an EITC corvette by outcast and one between tortuga and rumrunners.
EITC can be found(normaly) by Padres Del Fuego too.
There are Orges usually between outcast and padres.
The EITC galleons aren't too common but if yoiur out by Padres and Outcast you can find some.
It takes time.

Also once you get the grenades I say level them up as much as you can. You really don't want to end up like me and have level 13 grenades at level 38 nort.
