Suggested Level: 26
The 2nd boss who guards the solar crystal is a Ninja and Ranger hybrid. It’s located on the Western Chaos Tower, for specific location visit THIS PAGE (it’s located at A2=2)
His attack patterns
 Summon 4 ninjas: The ninjas are very quick and can attack in both melee and range, they have low HP though so you can kill them quickly
 Blade rush (3): Really dangerous and hard to evade. Movement speed will help you dodge this attack
 Incendiary arrow: Make sure you move from the fire on the ground that appears from incendiary arrow.
Bow and Armor are the best ones those available on The Capital: City Center
 Vintage Chardonnay (+ 5 weapon power, + 5% Life Drain)
 Choker of the Red Feast (+10% Life Drain)
Those accessories are available on the forbidden library once I reach level 25.
I only use premeditate on charm, so I can disable summoned ninja and make the boss attack it. It will give you a lot of time to deals damage to the boss. While the boss attacking the ninja, remember to use your multitarget attacks on other enemies.
Here is the video when I fought this boss
Video/Guide for other classes will come (If i play the game with those classes)
Please leave comment, if you have any questions, tips (for this class and other classes), etc.
