These tips are translated from Chinese C9 fansite, hope they can help Scout players :)
1. Number 0 button is the shortcut key of sheathing sword and running away, so you don't need to put a skill in the shortcut button.
2. Button Q not only can prevent ranged attack, you're also under invincible status in the instant of pressing Q(About 0.5 sec).
Eg. If you are combo attacked by Blade Master, although you dodge, Blade Master may use charge and close to you again, if the skills which used to escape or protect life are in CD time at the moment, maybe you can press Q, then use Evasive Attack(回避攻击) or Speed Arrow(急速射击), it's possible to strike back.
3. After pressing Q and hiding, except for nornal attack, you can use Evasive Attack(回避攻击) or Speed Arrow(急速射击) to cancel the status.
Eg. Ranger use Charged Aim(聚气瞄准), then you press Q to hide, usually the ranger will not release the arrow in this time, he will go on aiming at you and waiting invisibility effect ends, so you can use Speed Arrow(急速射击) before the hiding status ends, hit the ranger by surprise.
4. Speed Arrow(急速射击)'s speed is much faster than other ranged classes' skills, you also can use Evasive Dash(翻滚) while using Speed Arrow(急速射击).
Eg. When an elementalist are casting all ranged skills, as long as the distance is appropriate, you can use Speed Arrow(急速射击) then Evasive Dash(翻滚).
5. Buster Impact(破坏冲击波) has two consecutive attacks, and the invincible status will keep about 2 sec, after launching the skill, it will have a 0.5 sec un-invincible attack(normal attack) first, then it's invincible status. During the 0.5 sec, if your opponent response quickly and strike back during the time, the skill will be interrupted. So it's recommend to level this skill more than 7, attack range is about 130%, so that it can avoid the case.
6. Turn Slash(半月斩) is not a patent of Assassin, make use of the 1 sec invincible status of this skill, follow with Traps is a good trick in PvP, and Turn Slash(半月斩) can shorten the time of releasing traps.
PS: Turn Slash(半月斩) only can follow by action skills, then it can shorten the of of releasing.
Turn Slash(半月斩)+ Lethargic Mist(软筋香) / Find weakness(弱点感知) / Flame Trap(燃烧陷阱) / Fire Support(炮弹支援) / Buster Impact(破坏冲击波) is available, if necessary, before use the skills, please release Turn Slash(半月斩) first. Turn Slash(半月斩)+Enchant Fire(蓝冰之火) / Bullet Trap(钉枪陷阱) have no effect.
Eg. When you press E and grab opponent, how to max damage? Try to use E + Turn Slash(半月斩)+Fire Support(炮弹支援) + Buster Impact(破坏冲击波), if opponent is floated by Fire Support(炮弹支援), + Find weakness(弱点感知)
7. Pumpkin Bomber(重磅炸弹)'s attack range is a 2x2 square, an eligible Scout need to know jump and throw the Pumpkin Bomber(重磅炸弹), and an advanced Scount need to know turn round in the air, throw the Pumpkin Bomber(重磅炸弹) and knock down opponent. In order to max the knockdown effect, you don't need to always jump and throw Pumpkin Bomber(重磅炸弹) in far distance, you also can throw it in close range, it will let opponent hard to guard against.
Eg. When you are chased by Blade Master or Taoist, and you think you're nearly caught, you can jump in the air and transfer perspective, then throw a Pumpkin Bomber(重磅炸弹), it will probably hit the opponent, and the opponent will fall to the ground. Of course 'jump in the air and transfer perspective, then throw a Pumpkin Bomber(重磅炸弹)' is hard to operate, need more practice.
8. Many Scouts don't pay attention to Lift Kick(回身踢), but this is a useful assistant skill, it also is the only active floating skill of Scout.
Eg. Knock down opponent, release Flame Trap(燃烧陷阱), wait for the opponent standing up, if you want to knock him down again, but Buster Impact(破坏冲击波) etc. knockdown skills are all in CD, you can stand by your opponent and when he stands up, use Lift Kick(回身踢). Because the first reaction of most players will want to escape when they see Flame Trap(燃烧陷阱), so if you use Lift Kick(回身踢), it's most likely to float him and knock him down.
