Grenades......of course

[Edward Edgemenace]

Option 1: Catacombs lava with a healer. If you can hit the front left raider from way back there, the boss usually doesn't come with them.

Option 2: Outcast island. Collect 3 or 4 or 5 (depending on what you can handle) and run like mad to Maggie Rigrage for healing. Then turn and throw 10 smoke bombs then finish them off with anything. Even without someone else, Padres to outcast is 45 seconds of sailing, when you need ammo. (But bring a friend - the rounding errors in-game are enormous - 20% becomes almost double rep.)

Option 3: find the six spineskulls/flotsams. Use other weapons to take out flotsams, then use pistol or staff to collect 6 spineskulls, then throw 20 smoke bombs at them, then 1 siege. TP to French island for ammo.

No matter what option you use, be certain you use ONLY very quiet servers to level grenades. NO MATTER WHAT, make sure server is quiet.
