Favorite being the highest then Love and then Like
*Remember when gifting courting items they wont work if gifting to the same sex.
Companions also have levels of affection:
Lvl5 8000-10000 (max)
Also remember when gifting I think of this as world of Warcraft green common blue rare and purple epic being the harder to get you will gain more affection off the higher ones. I wouldn’t gift any further than 2 under your affection level as there will be no gain, gifting higher level will increase the gain. Thats all you really need to know really.
