i heard that in hellbound from each sub ull be able to pick on skill.
if it will be true, and u'll be able, what do u think will be the best compilation [class main +class sub with skill]

i was thinking about gladi +soul guard [OL]+ frenzy [DESTRO] + zealot [tyrant].

what do u think about it?

I don't think it's really like that. If it were like that i'd choose destro + angelic icon from pala + fist fury from tyrant + battle heal from bish.

As i understood if your main is a certain class, subs get some advantages.

some buffer+some summon+battle heal from bish+ some nuker from nuker or final servitor from some summoner. [1 buffer, 2summons, 1healer]
unbetale on oly.
1. summon>servitor>buffs> attack with summon and heal him> u pwn them!!

actually u earn a passive skill if i remember right when i checked that.Its about P/M atk P/M def . 5% i think check that==> www.l2.stratics.com

i don't see anythink about it- ican u quote it? ;]

You don't choose a skill of the subclass to your main.
There's 3 Skills that u can choose, and their are not any of the skills the class have. It's like a different skills.
If you choose ANY Warrior as subclass, u can get one skill that make u get +Stk Spd when Attacked (like Counter Rapid Shot, but for all weapons). If you have ANY summoner, u get one that you gain Atk Spd and Casting Spd when attacked (oO).

Knight classes gives P def, buffers do elemental resist.
And another many things. 3 Skills per Sub.

seems cool, might give it a try if it works

There's Skills if you sub (The SAME skill, whatever of your subclass is SpS or SH)

Mage (Necro/SpS/Sorc/SH)
Enchanters (a.k.a. Buffers) (Shillien, Elder, Prophet)
Warriors (Warlord, Gladiator, Bladedancer, Swordsinger, And I think Dwarves come here too)
Knights (DA, Pala, SK, TK)
Summoners (Phantom Summoner, Elemental Summoner, Warlock)

Well, I don't remember if Scouts come with Archers and Daggers together. But, whatever :p

It sounds really cool
