Amos, the Mortal Reminder

Passive - Vagrant
Amos does not use mana, but instead pays for spells in the form of the 6 bullets in his revolver.
Amos is a melee fighter, but can change to ranged with his abilities.
While in melee form, Amos does has [scaling number] bonus armor and magic resist and [scaling %] more movespeed.
While ranged, Amos does [%] more damage and must expend bullets to attack. The revolver does not reload on its own.

Q - Sharpshooter
Active: Amos switches to ranged form. This allows him to expend bullets to fire ranged attacks. It also changes W - Deft Feet to W - Deft Hands
Passive: Deal [scaling number] flat bonus damage (+%AD) on autoattacks in ranged form.

W - Deft Feet/Deft Hands
W - Deft Feet
While in melee form, Amos has access to a dash, which stops when colliding with enemies and cannot go through walls. After using Deft Feet, Amos gains [scaling %] movespeed for 2 seconds.
W - Deft Hands
While in ranged form, Amos can expend all current bullets (or none) to reload his gun, dropping cartridges on the ground equal to the amount of bullets left in the gun. Each cartridge remains for 4 seconds, exploding when an enemy unit walks over it, doing [scaling cumulative number](+%AD) damage and slowing them by [small cumulative percent] based on the number of cartridges. The reload speed of Deft Hands scales down with CDR.

E - Dartboard
Amos has access to [1/2/2/3/3] throwing knives which he can throw in both ranged and melee form. In melee form, the knives are thrown straight forward and collide with enemy units on impact. In ranged form, the knives are thrown in an arc to a location, allowing them to go over units and terrain. The knives do not use bullet ammo, but replenish faster in melee form.
Each knife does [scaling number](+%AD) damage, and ignores [0/5/10/15/20]% of the enemy’s total armor.

R - High Noon (melee or ranged)
If in ranged form, High Noon can be used at any time to shoot one bullet, however this does not benefit from armor rend and cannot be fired in rapid succession. The cooldown between shots increases based on the number fired until at the 6th shot it reaches full cooldown. (1+ minutes)

In melee form, Amos quickdraws his revolver, and for up to 4 seconds may aim 6 shots which, when the 4 seconds are up or all 6 shots have been queued, will fire in extreme rapid succession in the direction they were aimed, stopping at the first target hit. Each shot does [basic attack damage]+[low scaling number](+low %AD) and rends the target’s armor for 5% each shot. If every shot hits a single target, the -%armor bonus is doubled for the duration of the debuff. Amos may choose not to shoot all his shots, and 1/6th of the cooldown is refunded for each shot not fired for the first 3 shots - afterwards, the ability goes on normal cooldown.
Only Amos benefits from the -armor on the target.
