to automate the gameplay, for those who like to have a high level toon without spending hours to reach this.
i mean... thats the reason to bot. money is probably earned better elsewhere.
i made a nice ammount in wow too. but as you see it in HB. most users use it to level, to do pvp for them, just to ease up the combat. people who earn money with public bots are the minority i think.
i will give you some numbers, how much real money is in neverwinter:
selling prices (Goldbroker):
100g: 2.89$
1M astral diamonds: 15.98$
source:
Buy NeverWinter Gold,Cheapest Neverwinter Nights Gold For Sale-Nwgolds.com
other sources almost identically price
now think, you sell to this brookers. your cut in wow was about a third. NW is similar i think. 1/3 for you, 2/3 for brokers (is broker spelled with 1 or 2 o's? sorry, english isn't my native language)
so you will get 0.96$ for 100Gold or 5.32$ for 1 milion diamonds.
how long do you need to farm this?
gold:
a group of mobs at lvl 60 drops about 70 copper. add the greens, that drop sometimes, you will come to about 1 silver per group (usually 3 mobs) you cant sell greens to other player for gold. the AH supports astral diamonds only.
so you have to kill 100 mobgroups for 1 gold, 10.000 mobgroups for 100gold.
10.000 mobgroups aren't killed in 24 hours
diamonds:
you can earn 24k AD (astral diamonds) per day by doing tasks. some by doing professions. mostly you will get them from selling stuff in the AH. how much can you do in AH?
probably 30k/day, if you have a good day (many gems, some blue drops)
so on a very good day, you will have about 60k. thats a very good day, played by hand. not botted.
so you still need 16 days a 60k to reach the milion to cash out your 5.32us$.
face it. botting NW wont make you rich. it wont give you any real life income, cos your enery bill will be higher than your income.
but, if you like the game, and you especially like the endgame content, the bot will help you to achieve the endgame content without spending hours to level each and every toon.
