1, Law of Axe Landing Point; Draven's axe landing point is regular. If you stand still, the axe will fall under your feet or within 100 yards from left to right (it won't fall behind). If the axe is thrown out, the hero moves before hitting someone, and the axe will fall about 400 yards in front of the hero's moving face. For your understanding, the explanation in the figure is as follows. Draven is an adc with very high requirements for chopping. It's hard to play Draven well without walking or splitting. The judgment of the falling direction of the axe is the direction of the hero before the axe is thrown out and hit people. Therefore, if the hero of the other side sticks to your face, you must quickly adjust the whereabouts of the axe by moving it to cancel the attack. If you slow down a little, the system will judge that you didn't move after the attack, and the axe landed at your feet, so you can't fly a kite. If you shake it too early after the cancellation, sometimes Draven will move and twitch before the attack. Most players will face this problem. In addition to more practice, they can also master the shaking before the attack, and move immediately after the shaking before the attack. This is something that Master Dreven must master. Another solution is to open W first and then E to push the enemy away and then output. 2. You can't cut the axe all the time if you fly with Draven's axe. A large part is to master the range of the axe and the size of the hero model. Picking up the axe at the edge limit saves a lot of walking time and is more flexible in pursuit. I think this will probably be weakened after the fire in the future, just like Zach's passive organization, which used to be easy to pick up. After weakening, the falling distance is far, and the judgment range is much smaller, resulting in the hero's basically zero appearance rate now. It is necessary for every Draven master to grab an axe at the edge of its impact point. 3. Many Dreven fans are concerned about how many axes Dreven can have in three axes and multiple axes. I looked up a lot of information about this, but I didn't come to a convincing conclusion. I have done many tests myself and come to several conclusions. First, I tested the time that Draven's axe flew in the air. As you can imagine, this time is a fixed value. The flying time of the axe here refers to the time when the axe bounces in the air after hitting the enemy, excluding the time after hitting the enemy. This time is affected by the attack speed, and the time for the axe to fly back is fixed. After a lot of tests, this time is probably 1S (this time is critical, but I can't measure it accurately. The value may be 1. 1, 1.2, 1.3. Let's use 1.0 for discussion here). Draven 1.0 attack speed can have three axes (test results), two in hand and one in the air. This special attack speed is beneficial to our analysis. At this attack speed, adc attacks once a second. We regard Draven's throwing an axe (actually Ping A) as a period of time 1S, waiting for the axe (the time when the axe flies in the air) as a period of time 1S, and collecting the axe as a time (an instant). It takes 2S from when Draven throws the axe to when he receives it (throwing the axe 1S, waiting for the axe 1S). Let's assume that Draven is a professional acrobat, playing with three knives with both hands. The three knives are numbered A, B and C. The condition for playing with three knives well is to throw the other two knives after throwing axe A and before catching axe A, that is, 1 throws two axes, so the attack speed is 2.0, contrary to the fact. This reduction to absurdity shows that there are wrong conditions in our proof process, so where is this wrong condition? In fact, Draven is not a professional acrobat, but a professional magician. The second after he threw axe A, he didn't throw two axes, B and C, but only threw one, but visually and emotionally, we all thought he threw two. Explain in detail: Draven only throws 1 axe in the first second of the axe flight, which means there is a possibility that Draven never throws an axe with one hand but keeps spinning, just two axes alternate back and forth in the air. Using this theory, we calculate the critical attack speed of 4 axes, and the calculation result is 2.0. But in fact, when the attack speed is 1.5, I can handle 4 axes in the test. The problem is that the flying time of the axe in the air is inaccurate, which is about1s-1.3s. This difference has a great influence on the critical attack speed. The critical attack speed of different flight time is shown in the following table (automatically excluded if it exceeds the actual range). The critical attack speed of three axes is about 0.8, so it can be determined that the flight time of axe is about 1.25S, the critical attack speed of four axes is about 1.5, and the critical attack speed of five axes is about 2.5. Nevertheless, this is a relatively close data that I can measure, not an exact data. I look forward to friends with special testing tools to complete this work. In fact, on the whole, multi-axis has no qualitative influence on improving the output of Draven, and Draven does not need to attack speed very much. In general, a red fork is enough, and my red fork is rarely used. Uncle De has twitched with three-phase coordination and W acceleration. The article will be analyzed in detail after loading. I touched here. It is difficult to achieve an attack speed of 2.5 in actual combat. What Draven needs is attack and crit. That is to say, the maximum number of four axes that can be used in actual combat requires the attack speed to be around 1.5, that is, 1.5 attacks per second. For the attack speed of 1.5, as long as the three axes can reach the maximum output, the two axes will obviously produce ordinary flat A, which will lead to the waste of output, and the significance of the four axes will not be so great. Let's talk about the three axes first, which is what every Dravidian master must learn. Generally, the attack speed of the Dravidians is around 1.3. If he can only use two axes, he will definitely have a flat A after a while, and of course it will take a while. Generally speaking, it is enough for ordinary Delaware players to master two axes, and it is meaningless to deliberately pursue three axes and multiple axes. For master Delaway, three axes also need to be mastered, which can improve the output in a certain sense, while four axes and above are meaningless to improve the output. 4, Q skill damage calculation Draven uses the critical strike calculation of Q skill flying axe without additional damage. The calculation formula is: crit damage = attack power *200% (250% after endless)+attack power *0.85. After three-phase stress, the calculation formula is: critical strike damage = attack power *200% (endless back 250)+ attack power (three-phase passive)+attack power *0.85. We can calculate that the later attack power is 500, and the maximum crit damage is 500 * 2.5+500+500 * 0.85 = 2175. So if you want to hit a fatal blow, it is a good choice to use the force of three phases. In addition, Uncle De's critical action is different from ordinary action, and friends who observe it carefully must have discovered it long ago. 5. About the card Q The so-called card Q here means that the falling place of the Q skill will not cross the terrain. When standing in narrow terrain, 90% of the axe will fall under your feet, thus saving the time of picking up the axe and maximizing the output. In advance, card Q can only stand and output, and needs to grasp the battlefield situation and have a better lineup. Playing dragon or dragon at the same time can improve efficiency. Here are just a few places to get Q cards, and so on. Finally, you keep practicing.
