Hey guys just started, about the time the 6000 jewel event was going on. I did one 3000 jewel draw and got Huanglong. So couple of questions since i couldnt really find a beginner's guide.

1. Is Huanglong a good Eidolon to build a team around? Is thunder a good element to be using?

2. If i were to use Huanglong which soul should i be aiming for?

3. Should i save my jewels fora really good gacha event or does it really matter.

4. Should i be going through the questline as much as possible or spamming a lower level one to level up?

5. What do the sub-characters and sub-weapons do?

Thanks again guys.
