I meant half a day in LonaRPG - when you run out of time (Hourglass = 100) and the night or day begins.
So...
1) Go to the goblin tower
2) Save womens (lead them to the blue door or one of the rooms where the blue door should spawn)
3) Come in goblin tower again (everything respawn)
4) Save womens again and again (you can save about 15 per half a day)
5) Go to the Noer city for reward
Result - you will spend about 1-2 hours real time but you will get a lot of experience and money.
