NPC Affinity Guide

 All NPCs in the game that you can interact with via an shop, craft or enhaning has an affinity bar that are showed bellow their names when talking to them:

As you can see my Affinity with Yomi is really low. So what is this used for?

Every level you unlock you get benefits from the NPC services, this means for example that if I reach

You can level up gainning affinity exp, this means that if I get lvl 1 with Yomi she will let me buy SG restoration;

Okay so How do I level up the affinity with NPCs?

Interacting with them. If the NPC is an shop, buy items from it. If the NPC is an crafter, craft easy items from it. It doesn't count the stack you buy/craft directly, it counts how much time did you buy/craft so do it 1 by 1. You should see messages of affiniy gain in the chat every time you interact and also there is an limit every day, thats the problem and why you should start soon doing this. The mesasge when the daily affinity is capped should happear in chat too so keep an eye in that.

The most importants NPCs to level affinity are Janice and Trisha (Crafter and Enhancer). Both are neccessary to be leveled up asap to at least lvl 3 because Janice gives you 20% craft items reduction and trisha 3% of extra enhance chance which is really cool. With janice you can craft low level craft items to higher tier 1 by 1, with trisha you can swap enhance low level tier items 1 by 1.

PD: Affiniy Levels with NPCs aren't shared among characters.
