This is a guide about the choices in levels for almost every skill and information with techniques on how you can use it. Contains mostly PvP stuff and will only say what you would want to do if you are wanting to PvE as well.

Level 6 Rising Slash for additional hit and connection to ariel combo.

Level 6 Imapct Wave for those times in PvP where you have no more lifts and you can't afford to drop.

Level 6 Destructive Swing for invincibility frames and utility to knock someone down.

Brush Off: Max it for PvE purposes to shrug off those deadly burn debuffs :(
Level 3 in PvP for ability to shrug off 2 debuffs.

Health: Max it because I do not know why you shouldn't max this. Good for tanking in PvP and staying alive in PvE.

Mana & Mana Regen: Don't you just hate it when you run out of mana in PvP and then you can't do anything as you await punishment to your HP. I guess it isn't really needed in PvE considering you have a Taoist that can use healing chakra to regenerate your MP. It is your choice if you want to get it or not.

Ariel Evasion: Max so you can stay alive!!!! Why wouldn't you max this!?!?!?
Tumble: Max Tumble definitely for dodging in PvE and PvP and also to initiate Dash faster.

Optional - Soccer Kick: Ehhhhh, if you have an extra skill point you can't find to dump into I guess.

Frenzied Charge: What? Level 11 Frenzied Charge for a Magic User!? Frenzied Charge is a killer move and does some nice damage >IF< you hit all three hits. Best way to do that is to use it against a wall. FCharge is also good as utility to catch an enemy from far away.

PvE: if you do not want this skill, dump the skill points into maxing Brush Off or put it into Parry, Parry Stance, etc.

Courageous Shout: Max it for the full buff duration for a boost in extra damage for 15 seconds in PvE! 7.5 in PvP I believe. A very good skill to paralyze the enemy for a few moments as well in PvP.

Luring Slice: Level 8 because it doesn't increase the damage buff after that level. 50% is a huge debuff in PvE and it lasts very long too. Combine it with CShout for a 80% damage debuff taken to enemies! 25% in PvP is still very good and you can deal a lot with Moonblade Dance and Crescent Cleave.

Counter Cross: Why level 6? This is a very nice damage skill evasive for PvP, and somewhat alright in PvE. At level 6 or 7, it can deal a nice bit of 6-14k depending if it crits to someone. You can also hit TWICE if you aim it right!

Cyclone Slash: Level 1 for utility in PvE and PvP. It doesn't do very much damage. The debuff for 30% damage in PvE and 10% in PvP is pretty good. Player will QQ when they can't Ariel Evade out of the extended range of the EX.

Moonlight Splitter: Impressive damage in PvP and a hurting skill in PvE. You can use this to stall the enemies on the ground or in the air. It does not scale well in damage after level 16. That will save you a bit of points. But if you want, you can max it for that extra bit of damage.

Technique: Use Impact Punch, Rising Slash after using Moonlight Splitter EX on the ground on an enemy in PvP. MLS EX will stall the enemy, leaving him hopeless on the ground.

Aim torward the ground and not actually at the enemy. It will create ripples of sword energy to stagger them.

Crescent Cleave: A MONSTER of a skill. Should be Maxed AND equipped with a Tech ring for +16 skill level. Be sure you HOLD S DOWN for damage in a VERY narrow angle. This can lead to FORTY THOUSAND damage in PvP to a player inside Cyclone Slash and is fully Debuffed with Luring Slice and CShout. in PvE, the boss will take a nice bit of damage if all the hits are in. It is a very nice DPS skill.

Technique: Wait untill the enemy in PvP is VERY low to the ground. Unleash the narrow variant of CC EX and watch the beautiful 2-4k numbers pop up everywhere as he glides along. This will maximize the damage output.

Halfmoon Slash: This skill is amazing and the absolutely hardest single hitting skill a Lunar Knight has. The EX gives it a whopping 10% additional pain and an extra 30% damage to a second slash. This is a whopping 43% more damage in PvE and 30% in PvP. If the second hit doesn't hit in PvP, the second will surely stagger you.

PvE: Go for a Damage Crest, no need for an action speed crest as the EX will come with speed.
PvP: Action Speed Crest isn't required but sure is helpful. It does not benefit from casting speed in PvP.

Technique - PvP: Use this against a wall for a guaranteed wall bounce twice with the EX.
Can be used to attack an enemy while his dodge skill is on cooldown OR to bait his dodge.

Moonblade Dance: Level 12 for MAXIMUM POWERRRRRRRRRRRRRRRR.
NO BRAINER HERE, ITS ♥♥♥♥♥♥♥ AMAZING SKILL AND SHOULD BE MAXED WITH A DAMAGE INCREASE PLATE AS IT WILL DEAL SO MUCH DAMAGE IN PVE AND PVP ENEMIES WILL QQ WHEN THEY FEEL THE WRATH OF THIS AWESOME YELLOW PISS SKILL.

Flash Stance: This skill sucks balls in terms of damage. It is ok damage in PvP and is good for support from far away or to stagger with right click.

Pasives and EXs: OBVIOUSLSY GET IT!
