Yes you can but you will have to go back to your Dark Elf starter zone or the next zone higher then a start zone (Gludin and Gludio for example) if you want to learn the skills for your class once you meet the level pre-req.
Bladedancer and gladiator are the only 2 classes that get masteries in dual swords. Bladedancer is DD/support, always wanted in groups, and glad is pure DD.
You can start finding groups in catacombs and necropoli when you are level 20 and have done your class change (sign up for 7 signs to gain access at priest of dawn or dusk, depending on which one wins on your server - it's usually dawn).
Is it possible to goto the human start zone as a dark elf?
I'm playing a Dark Elf and my friend is playing a Human.
And, yes, im a total newbie :)
I'm biased, but I think DEV has better hunting spots than TI.
Besides...it is unbecoming for a Dark Elf to cater to the whims of an inferior species. Are you not Shillien's chosen? Have you no spine?!? Tell the Human to come to you! :D
Just because you can use dual swords at D-Grade (20+) doesn't mean you should. A 2-Handed sword will deliver the best DPS since, as a Palus Knight you get Sword/Blunt masteries which affects 2-Handed swords but not Dual Swords. Top D 2-Hander has a base patk of 112, top D duals have a base patk of 107. The 112 Patk combined with your high STR and Sword/Blunt masteries will make a Claymore the obviously better choice.
Once you hit C-grade (40+) it is necessary to get Dual Swords as you can not perform your primary function which is Dancing. Dances are buffs that affect the entire party and stack with normal buffs and that makes you wanted in nearly every party.
