..and SinX has far higher damage output.
If both of them know nothing but rush each other and start BB/bash/SB each other, SinX is likely to oneshot LK given good equip. If LK's got some skill, he can easily take out the SinX. If SinX have skill, he won't give LK much chance.
yeah sinx is a hard enemy...because sinx can hiding and cloaking..and use EDP..
but LK will win if use a good equip and use a skill area...
Skilled Sinx > All other Melee Jobs.
Doesn't really matter if LK has or not good stuff (Inca = Byebye DEF), only Element, Size and/or Race reduction can help LK. As it was say, LK wears Ghost, so, Cursed Water and ther it goes Ghost. Without Link, only EDP and that katar can 1 shot KO that LK easily, and if he doesn't die, I'm sure than after that he'll berserk (like almost all LK). LK can have a lot of HP... But don't forget, Sinx and Palis have one of the highest HP Modifiers in the game (the highest one is LK), so .::AsSaSsiN-X::., is not an excuse than LK has lot of HP, cause Sinx also has lot of HP... and Sinx has also more destructives skills than LK has.
I think that if that sinx is medium experienced and that LK is medium experienced, Sinx can easily win. But if LK has more experience and skills than Sinx has, it could be dificult for that Sinx. As an unexperienced LK (i mean, if you are LK and don't really know how to act against that Sinx) I would wear High Orc, well upgraded Valkyrians Manteau, Orc Lord, Thorny Shield + Bison Horn and Sheep Hat (if is it possible). That will reflect (+7 Valkyrians) like 64% Physical Damage (if your HP is like 25k, he must hit you 25k in orther to kill you, but he'll receive back like 16k damage). If Sinx 1 shot KO you, there's high change that he'll also die (depends on his HP). If he's low HP and you can survive, he'll probably die. If you are not sure you can survive, you must wait until you can see him goin' to atack you, so go berserk and he'll die. If you die and he survives, change that shield and use a strong shield (with Hig Orc or, if still unsure that reflecting damage won't hill him, with alice). Im' sure that after he dies by his own damage, he will not try you anymore or he'll only try either soul destroy or grim.
