Lvling Grenades When You're Notoriety is High

[ruisen2000]

I use gathering method when leveling my gun, i gather all 3 unchinfists/thralls together wth a pistol, then when they're in front of me i fire away with my blunderbuss!
For treasure room i prefer to use seige and bomb all 4 sea beasties at once, only 30-40 rep at once, but lots of fun!
