help me to build enchanter

A better weapon would be Pramia(Fire), Lumekining(need to be lvl 230 to get, Water), and/or Jupiter(Wind, high lvl production item). Of those 3 Pramia would be the first in reach.

DPR is good until you can get an Emido. It has a ton of really good stats.

Magia Hood is much much better than Ciel and not very expensive so I also recommend getting that. In general if you are relying on autoskills for damage you should stay away from any sort of Neutral autoskill as they all do poor damage.

Lotus Seeds Ns is something you can easily farm, its dropped by Kijimus on Starfall Road near Sofya City. The stats are Autoskill +5% and Crit Rate-20%. A better option would be Javali Bangle, it reduces Attack Interval by chance when attacking. It makes you attack twice as fast when its active, and if you have a good amount of Autoskill % that will be almost all the time, so its a huge DPS boost.

Xtals are a whole other story and Enchanters got some expensive ones.

Oh and for stats you want max INT ASAP. 135+ AGI for max ASPD, then you wanna max DEX and add a bit of VIT, like 50 or so. Then proceed to continue on with AGI. After you stat release INT is your top priority followed by AGI and then VIT. This is for Autoskill builds as Magic Blade spam isn't really suited to DPS as much.
