HM farmin vs nm farming

is it better to farm late in the game in nm better than farming hm early in the game?

Hard Mode has a larger variety of items which may be deemed more profitable than Normal Mode.

Hard Mode.... anywhere.

Hardmode drops = worth more gold usually.

So on average you will probably make more from fewer HM drops then you would more NM drops in any location. But im not saying that for certain.

Ive found just doing missions over and over again give ample supply of drops to make 2-3k each run. Just replay a few HM quests or missions or dungeons and sell all the drops to merchant.

Thats how I do it (a good one being the snowman dungeon in HM makes a small bit of gold and nice xmas treats at the end).

Hard Mode has some drops, such as Tomes, that don't drop in normal mode.

Although I found quite a difference in the quality of drops when I vanquished Elona (and most of Cantha), I haven't (yet) been overly impressed with the HM drops in EoN.

im kinda new what is hard mode and how do i do it?

U gain Hard Mode if u complete a campaign, when u did the last mission u will gain Hard Mode, then appears in your P ( Party ) Screen the button NM ( Normal Mode) HM ( Hard Mode ) With a Yellow and Red picture.
