Elyos Leveling Guide (37/38) - 40
This is a great place for you to level starting at level 37. The Kysis Flame Tribe mobs are pretty darn squishy and don't hit for much. Also this place is pretty out of the way which means not many people will come over here to gank you. In addition if your faction owns a nearby Artifact or the Keep then you will have some place nearby to run incase anyone does come your way.
As if it wasn't enough already that the Kysis where squishy, gank free and didn't hit very hard they also drop Kinah. There are two camps of Kysis you should know about. One camp has Kysis that are specifically level 39 the other has Kysis that are level 38. At level 36/37 if you come here you will want to kill the Kysis at the Red circle on my map below. If you are 38/39 you can head over to the Blue circle and kill the higher level ones.
Loot:
200 Kinah Each
Mana Stone
Armor Flux
Weapon Flux
You can hang out at the Kysis until level 40 or switch it up at level 39 depending on what you prefer. A good place to go at level 39 is the Drakes just north of you on Kysis Isle. There are quite a few drakes here and not many people usually venture up here.
When you hit level 40 where ever it may be, it will be time to leave The Abyss and merge with the "Outside of The Abyss" Leveling Guide.
