how are you going to tell him to max es and not get telekinesis? no offense but that is some horrible advice.

to the guy with the question: you need to get telekinesis as high as you can as a synergy to es so it reduces the amount of mana you lose everytime you get hit. if you don't get telekinesis and duel, 1 hit will usually eat all your mana and the next hit will kill you. theres no need to max es because it levels off as you put points in it anyway (diminishing returns). +skill items and buff is plenty good for casting a es.

heres some gear you can use to buff es if you don't mind people *****ing about bm:

+9 es memory stick
+3 es ormus
+3 lightning circlet
+3 ammy
+2 on 2 rings
+3 on torch
+1 on anni
+9 skiller gcs
+1 from bc

adds up to a total of level 35 es if you only put 1 point in it.
