What does leveling Night Devil Do?

Okay, quick question, simple answers xD, i was too lazy to look on the co site.. not sure if it's even on there. What does leveling night devil even do.. just change it's color? Health? Speed it hits? or none. xD

gives your more speed 3x than normal.......... so..... if you tg with ND..... you will gain experience faster than using robot or water elf......... its good also in lvling nix...... it gives you more speed means faster dropping rate of nix.....

Magic Def, Health of ND, Speed Hits and its color.

ND is good against magic attack, terrible against physical, good to use in death tactic if you wear strong gear. Fast attack, longer range, good to use in TG to hit faster or double stakes, other then that not much else since it was weakened 100 or so patches ago. As for leveling your on the money, but it also last longer, which is a downside.

Well, i was just wondering if lvling it helps :p i've had it.. but never used it outside tg, so it does increase speed?

yep

i looked on co forums and asked in game when i was lvling nix, everytopic or person i asked said it only goes for longer there is no speed boost by lvling nd
