Well... you have several choices ... its up to you , what you like
to play and do you like to do massive dmg and die alot or
do moderate dmg and survive alot ....
Let me tell you good sides and bad sides of every build
Warrior: <<Make it full STR.>>
S/S- great tanking ability ...
doing lowest dmg from all euro classes but not as low as blader.
If you want to be last man standing ... make s/s
(sub-cleric)
2Handed-my favourite one ... doing great dmg (highest of all three clases of warrior) ...
has knockdown , stun and knockback ... I just love it ....
(sub- cleric / bard)
Axe- Not much people like this build ... they perfer s/s or 2h ....
tho it has some good passive buffs ... but IMO , dont make axe warrior ....
It has some nice combos tho ... but .... dont make it xD
(sub- cleric / bard)
Rogue- <<Make it full STR.>>
Okay ... this one is nasty ... if I can't make 2 handed swordsman ... I would make rogue.
Crossbow and Daggers ... great .... Rogue's tanking ability aint so good ...
It will happen you die alot ... but dont worry ... it grinds fast and relly...
IMO I think he destroyed balance in SRO ... High hp , High dmg ....
(sub- cleric / bard, tho I perfer bard)
Wizard- <<Make it full INT.>>
highest dmg in SRO , fastest leveling ....
has alot of sp to farm ....
dies hell of alot .... has some nice skills...
I suggest you to make it if you want kill alot and level up fast.
(sub- cleric / bard)
Warlock- <<Make it full INT.>>
I cant say much about that build ...
I know it has nice surviving ability ... it can leech hp ...
give curses .... it takes time from him to kill .... but ...
not much people make Warlock ... (as I saw from my expiriance)
If you wanna be unique ... make it
(sub- cleric)
Bard- <<Make it full INT.>>
Well mostly you will use it as sub-mastery ...
dont take it as primary

just forget it
(sub- cleric)
Cleric- <<Make it full INT.>>
Really awesome build.... every one wants it
in party .... not the dmg dealer of party ... he supports , buffs and heals ...
tho it can make highest dmg in game with pure-offering.
I like it ... thats next euro character I'm going to make
(sub- wizard / warlock)
