I'm not sure what a 1:7 hybrid is...maybe a mag balance of 85%-90%
I'm pretty sure with a spear, this build would deal a ton of damage, but most people with this mag balance usually tend to choose s/s for the extra defense because of the lack of HP. I'm no expert on this, but I think a spear would be okay with the hueksal passive. You might actually want to wait for someone who has had experience with this build to post though, don't listen to me
90 ice would definately be needed though
Anyways, here it goes:
1) Will Lightning/Cold/ Heuksal be enough skills for this build.
Yep, definately! You might want to take fire to 30 for a little extra immunity and the first nuke.
2) how much hp will this build have at lvl 90? With the Heuksal Passive included of course.
Er, I'd have to calculate that..probably over 10K atleast
3) will this build be affective in grinding and in pvp at 90?
There are spear users like this at 90 cap, and with the extra cold defense you should be fine.
4) how many lvls of pure str will this build need? i think its full str till lvl 11, then int all the way.
Well, I wouldn't do it that way. When you get to level 30 you want to have a high mag balance for the nukes, so maybe throw in some health after level 25. I'd probably go full int until level 25, then maybe alternate. 3 Int, 3 Str, 3 int, 3str...or just do whatever you need to.
5)how will this build compare to pure int sword? i know it will have more hp, but wat about dmg? and which one will have higher defence?
Assuming both have cold maxed, same equipment, and the same mana shield, higher defense would be the s/s nuker...they have a shield, remember.
6) wat armor would i wear? i was thinking protector, but will garment be reasonable?
Protector will work well, but when you get the extra 42 defense from the ice passive/buff you can switch to garments I think.
7) for this build, do i have to take bow to 30 just to train faster?
If you want to! Another option is getting pwrlvled at the ongs. You can get to 30 in almost a day without sp farming.
