The core of her entire kit. Using any of your abilities gives you points to a system unique to Mulan called Skill. You gain points of Skill every time you use an ability that deals damage, the amount of points you gain is equal to the amount of damage dealt at an enemy god. You can also gain Skill from attacking minions but that stays at a flat percentage for each minion hit. That's not all, you also have a little meter that when filled reduces the cooldown of all your next ability. Note: This CDR dose does not affect your ultimate.
You hit in a 180 cone in front of you twice, that's about it... Or so you thought.
When you become Skilled: You gain an attack speed increase for a short duration after using this ability.
When you become Adept: You deal an additional attack in a large cone in front of you.
When you a Master: You gain a permanent passive effect that provides a percentage of attack speed that stacks with the steroid you got when you became Skilled.
This ability will act as your main clear as it deals the most damage out of all 3 of your non-ultimate abilities. It can also help with taking objectives like Totem or towers when you become Skilled with this ability.
You thrust your spear forward, hitting and slowing all enemies in its path. As simple as this ability is, there's more than meets the eye.
When you become Skilled: You gain health for each target hit up to 3.
When you become Adept: You gain an additional attack.
When you become a Master: You gain a permanent passive effect that provides a percentage of physical power.
Mostly used for close-range poking as well as sustain during laning and team fights. You want to use this as your fist ability to utilize the slow if you want to save Grapple later on (we'll get to that).
Standing still, you fire an arrow tied to a rope. If you hit an enemy god, they become stunned and are pulled to you while you're pulled to them. When you meet each other halfway, you attack the target. As you guessed there's a pattern with her first three abilities, and this one is no different.
When you become Skilled: When you successfully connect with a target, you gain physical and magical protection.
When you become Adept: At this stage, you gain the ability to use to pull yourself to a wall.
When you become a Master: You gain a permanent passive effect that provides a percentage of movement speed.
This is either your engagement or escapes depending on how you want to use it. You gain the benefit of protection before you start a fight or chasing a fleeing target. As an escape, you will need to become Adept in this ability before consider using it as an escape option.
Dashing forward with your sword attacking three times in the dash after that Mulan roots herself and slams down her spear knocking up all targets within the radius of the attack. After that, she fires an arrow from her bow passing through all targets it hits. Mulan gains Skill from hitting enemies with the respected used during the stages of the ultimate. This is a great tool to use to not just set-up/disrupt fights but also as a way to accelerate her abilities into the next stage in their evolution.
