Suggested Level: 24
The 1st boss who guards the solar crystal is a necromancer and barbarian hybrid. It’s located on the Eastern Chaos Tower, for specific location visit THIS PAGE (it’s located at D3=3)
His attack patterns
 Summons 4 skeleton warriors: You can affect these skeleton with charm, stun, etc. If you have charm skill (like my ranger build), I suggest you use it on skeleton mage, because it can heal other enemies.
 Tornado: It will slow your movement, and please don’t tank this attack (especially if you’re a range character), because it deals a lot of damage!!
 Quake: It’s like Barbarian Skill, you can evade this attack simply by going left or right (He always does this 3 times in a row, so don’t stand after evading the first quake!!).
 Red Body (???): His defense is going up drastically!!
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.
Here is the video when I fought this boss
I only use premeditate on charm, so I can disable skeleton mage 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 skeleton mage, remember to use your multitarget attacks on other enemies.
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.
