First of all i wanna tell you all that it doesn't matter if you're hero if u'r main is a buffer [that is on high rates] . I mean , wtf ? are u gonna pvp with your buffer ? NOT! What i'm trying to say is that u must get hero on some pvp-useful main's . Like bishop(my favourite) , he , aw , th , etc etc .
Bishop(Cardinal):
1st (the 60 seconds) Buff yourself using a robe , weapon:Holy Staff (can't remember exactly the name - it's a C grade wep) with body blessing SA
2nd (the 20 seconds) Equip a heavy armoor , with duals and get ready. (that is if you don't have any att augment)
3rd(the fight) First , mass block shield and mass block wind walk . So you can do more damage and he's got less speed(you can hit him) . Then , if he's a mistic/archer/or whatever uses mana , just Hit+mana burn , at a certain point , he'll run out of mana (if you don't get killed till then) and the match is yours . IMPORTANT: Use Greater Heal , not Greater battle heal because it consumes too much mana so u will not hang on more than 2 minutes.
[[[-> Another tactic on some servers , where the trance chance is 100% , hit him till u'r sure his cp and at least 5% of hp ran out and then keep sleeping him (using trance) till the end of the fight .
Paladin(Phoenix Knight):
1st(before the oly match) Get like 5% hp and some cubics if possible
2nd(60 seconds) Buff yourself , and before the 20 seconds use Angelic Icon (for this you have to follow step 1)
3rd(the fight) first of all try to shackle him several times , then just get to him and stun+hit . (Other important skills:Shield Slam(takes out enemy's target) , Judgement(3x normal damage) . )
4th-Calculate how much does an oly match last , and if ur' not dead till 20 seconds remaining till battle is finished , spam stun the target and keep healing yourself + Touch Of Life
Important notice: If u'r dealing with a bishop , spam aggro on him when he's healing himself . This way you can thank him for winning the match.
Spellhowler(Storm Screamer)
1st(60 seconds) Get the bodly blessing C grade staff and buff yourself with Shield and Concentration (keep using the skill on you untill u get the bless the body from the SA - don't pass the 20 seconds because u will be using the fight mana )
2nd(the fight) If mistic , try to silence on him , maybe ur lucky and KO your enemy. Use Wind Vortex , Surrender to wind first(and then repeat on a interval of 20-30 seocnds - depends on the server) and then use Hurricane and Aura Flash if enemy is a dagger (takes out his target , close mass attack)
For any other classes , post a request by a comment on this topic .
EDIT:
Overlord(dominator)
1st(before the match) Get the body blessing C grade wep
2nd(60 sec) Buff yourself: Glory of Paagrio(m def) , Power of Paagrio(p atk) , Shield of Paagrio (shield success rate) , Wisdom of Paagrio(cast spd) ,Blessing of Paagrio(p def) , Sight of Paagrio(accuracy) , Eye of Paagrio(focus) , Soul of Paagrio(m atk) .
3rd(the fight) Equip a heavy armoor , and a blunt . Hit the enemy with the blunt till your cp is down (+hammer crush) . Then , equip a staff , activate Arcane Power , and hit the enemy with steal essence . Also try Dreaming spirit+seal of binding (if close range enemy) , Seal of silence(if mistic) , seal of despair , seal of winter(if fighter), Seal of Slow(if binding not successful , close range enemy) . IMPORTANT: don't use ritual and the ally restore cp skills , unless you can use MP pots.(the mp consumtion of those skills is imense , so it doesn't worth)
4th- If close to the end of the battle , and none of you dead , sleep the enemy and recharge ur cp .
