There is a "rumor" called NPC relations which affects the character in general. Well, it's not a rumor, various in-game actions affect the way the NPCs "feel" about your character. What can't be easily proved is what someone gains if he is doing his best to achieve maximum relations with NPCs?
I was wondering what happens with NPC Relations in general and how the game converts my actions to points, so I decided to make a new char and start checking relations according to various things I did in game.
I made a new char and "cheated" to make him lvl 145 , afterwards I started doing stuff. Click the image on the right to see what happened after each action.
As a general rule, it seems that relations have a max of 32k points, various actions in game affect the points you get. e.g. Selling items to NPC, doing quests etc.
The next time I will try the following scenarios:
Quanato PK Temoz
Quanato PK Quanato
Temoz PK Quanato
Temoz PK Temoz
Crafting & Modding of items:
Craft G9, G10
Make G7,G8 item mounted
Add +AA or Bless to G7+ item
If you have more information (with proof) on NPC relations then either post them here or in http://forum.ragezone.com/f98/
