What is the glory of King Old Master Q's skill?

Gas field broke out in Old Master Q, moving speed increased by 25/28/3 1/34/37/40%, and damage was reduced by 50/54/58/62/66/70% for 2 seconds. At the same time, it will rebound the hero's ordinary attack, causing the same physical damage to the attacker and reducing his movement speed by 50% for 2 seconds. Rebound will be accompanied by a normal attack effect on orb, and each enemy will be bounced at most once.

Passive: Every ordinary attack has a 25% chance to launch two ordinary attacks, and the second ordinary attack will only cause 50% damage.

Old Master Q plus point method:

With the improvement of skill level, Old Master Q gained a lot of skill one or skill two. Adding a skill can extend the deceleration range and duration of the additional deceleration effect after hitting the enemy, and adding two skills can improve the movement speed and injury-free range after opening the second skill.

The mainstream way to add points is the main pair 1. Of course, if you like the main pair 1 or 12, the same point is also possible. As for which skill to point out from the beginning, it doesn't matter, it is possible.
