I did the same thing on my NG+ run in the game, because I was using light armour :P on my first time around I was using a very Heavy armour set, and got blown up by a ball and then ended up being gobled up by 4 slimes XD I laughed so hard :P
I had luck with the Hardstones in 2-1, I found three miners with sacks that gave me a huge amount of Hardstones, enough needed to go from Bow+3 to Bow+7 immediatly xD
Also, I'm using the Purple Flame Shield+1 and a Winged Spear +3 or a Mail Breaker +7 as my main attack weapons, no spells yet (i'm only saving up for Warding though, I think it's the only necessary spells for me, at least until I get to NG+ again).
