there is a skill reset item but its a cash item, and seeing that we are all playing overseas....we don't have the won (thats korean currency) to pay for the cash items. So here is my suggestion:
make every type of character, Elsword, Aisha, Rena, Raven, and look at their skill trees. Browse through their skills and decide which skill path you are going to take. Make a few of each character, test out all the skills, and go from there. By the time you reach lvl 8 you should be able to acquire lvl 1 of Skill rank 3, given you save up all the skill points. And going to lvl 8 takes at most what...1 hour? less?
As for whether you should go Sword Taker or Over Taker....its up to your fighting preference. If you like to hack n slash, then go Sword Taker, he has some cool non-skill moves that can keep your interests, I know it did for me until leveling became a pain.
Go Over Taker if you like massive aoe attacks with imba cannon dmg from your nasword arm. Imo, Over Taker is for crowd control, and Sword Taker is for 1 on 1 situations.
Anyways, pm me if you guys see me online, my IGN is Overlimit, UrisOmega, or OmniFire. Though atm I am focusing on Overlimit to try out Magic Knight class.
