12+4 fast casting
12 water magic

ice spear
(5 energy, 1 casting time, 0 recasting time)(after fast casting has 1/2 cast)
flies toward target foe hitting for 46 damage if it hits, has 1/2 the range of a normal spell

water atunement
(10 energy, 2 casting time, 60 recasting time)(after fast casting has 1/2 cast)
for 55 seconds you gain 30% of the energy cost for water magic spells

aura of restoration
(10 energy, 0 casting time, 20 recasting time)
for 60 seconds you gain 152% hp of the energy cost for spells

with this build i could cast 2 ice spears a second, and according to "The Edge"
i would have about 50 mana (from items and armor), so i should probally be able 2 cast about 14-15 right in a row because of mana regen and water atunement, while healing myself quite well (about 15 hp every cast and about 2 casts a second)

is this a good idea (maybe there is something im missing that makes the information i have wrong, like having to waite so long before you cast another spell), and what other skills could i bring to make it better, or what attributes could i change

It might sound ok on paper but its really not that much damage. You have to be way to close to use Ice Spear to make it effective. I find the Water line is better for AoE damage such as Maelstrom, but if you want single target damage in Water go with Trident. I like to keep Fast Casting between 8-10 because you get the most out of your skill points in that range. Add on another attribute line or get some more skills in there (you get 8, why try to work with fewer?) and complete your build.

Let me put it this way .5 second cast + .75 second after cast for ice spear makes it slow add in the fact that 43 damage is before armor and a simple conjure frost wand attack does a similar amount of damage... so why waste energy?

what if i changed it to fire magic and did flare, tiny bit less damage but dont have two be as close

and from what i just read on another forum a guy said that he is pretty sure the .75 is only added if you use the same skill twice, so what if you did like a arcane echo and then spammed those 2?

No, as I have just learned the .75 seconds is added on to any skill that has an animation. Flare is the same thing, it just isn't that much damage for a lot of time and energy. A simple Conjure XX will do just as much damage as spamming Flare for much less energy and it will allow you a lot of other possibilities with your build.

ok so mabye i was wrong about it doing the same damage i think with flurry it comes close again? anyway back to the subject this still doesnt change the fact that flare,ice spear, and stone daggers suck its just not worth it in reality the DPS is just sub-par. Its not efficent and the only way to make it efficient is use up more skills on your skill bar which is worse. Rangers/warriors can easily out damage any elementalist set up to spam skills. I'm not saying elementalist suck either just that the setup you suggested isn't going to have the damage you desire.

Sorry dont mean to come off like an ass its just the way the skills are setup and the fact that you can't readily see how it works unless you have tried it.

i understand no offense taken draken, i trust you know a little more about the subject then me, ill just scratch the idea and work on a dif build i just needed some other opinions from people with a little more experience then me

Look at the elite skills develop a build around one that you like. This is not to say that all elites are good but most of them are elite for a reason . Also check out the build section on this site alot of them are good.
