best way to increase skill levels, particularly those of combat skillls and more notably that of holy shield. ed on places other than the weapon does affect smite some, but 1 to skills will actually effect it noticeably. so I wouldn't worry about ed. Of a choice between redeemer and heavens light, I would go with the redeemer. that +damage modifier transfers to smites base damage, and bypasses the pvp penalty. If you are playing pvm, then the heavens is better, with crushing blow, more sockets, and higher skills. If pvp, then only against high life opponents (4-5k or more), then crushing blow can make a big difference there. Otherwise, go with a redeemer. Since you are trying to reach 6 fpa without fanat, you really will need a phase blade. try shopping for a phase blade, then using flawless gems on it until you get a rosebranded (preferably of quickness and with 2 sockets). However, if you get such a weapon, optimal socketing would say ber ber. However, you are hinting that you cannot afford it, so shaels or ums would be best. Just make sure you hit 65 ias total. With that and a phase blade, you are hitting 6 fpa smite. Anything else means that you probably won't hit 6, at least not easily. good luck!
