Werien, the Adaptive Predator
Here's my new concept on a champion that literally adapts to the game.
Werien is a semi-tanky skirmisher than can become a fighter or an assassin. Werien is melee.
Abilities:
Passive: Adaptation
This is the signature part of Werien. Passively, Werien forms Adaptations based on what he encounters in the game. There are 6 possible Adaptations, shown here:
Night Vision: Enables Werien to see stealthed units outside of brush within a short radius. So this is pretty much just a weaker version of true sight. Werien gains this Adaptation after being near 5 stealthed units total, and this doesn't count for units inside of brush (unless they activate a stealth ability inside of a bush, such as Teemo's passive). Visual effect: Werien's eyes turn green.
Swiftness: This grants 15 movement speed to Werien, and reduces the effectiveness of slows inflicted upon him by 15%. Werien gains this Adaptation after being outrun by an enemy champion or being unable to outrun an enemy champion 5 times.Visual Effect: Werien's legs become muscular.
Honed Claws: Werien's basic attacks ignore 15% of the target's armor. Werien gains this Adaptation after killing 75 units. Champions count as ten units for this.Visual Effect: Werien's claws are larger and sharper.
Hardiness: Grants 20 armor. Werien gains this Adaptation after he has taken 2500 total physical damage. Visual Effect: Werien becomes bulky. (Can't think of another way to word this)
Resistant Fur: Grants 20 magic resist. Werien gains this Adaptation after taking he has taken 2500 total magic damage. Visual Effect: Werien's fur turns into a darker shade of brown.
Bloodthirst: Grants 10% Lifesteal. Werien gains this Adaptation after being below 50% health OUTSIDE of base for 3 minutes total. Visual Effect: Blood drips from Werien's fangs.
Q: Weakened Prey: Werien causes a target to bleed, dealing 20/40/60/80/100 +80% AD physical damage over 4 seconds. During the duration, Werien has additional effects (I'll cover it later) and the target is slowed for 16/22/28/34/40%.
W: Pounce the Prey: Enters a crawl that slows you for 90/85/80/75/70% for 3 seconds. Over that time, your next attack will gain range and will cause you to dash rapidly towards the target. The range is increased the longer you stay in the crawl. That attack also deals bonus magic damage equal to 10/12.5/15/17.5/20% of their missing health if your Q has been used on them. You gain a quick MS buff as well once you reach the target.
E: Ravenous Frenzy: Gains a surge of decaying 70/76/82/88/94% attack speed for 5 seconds. During this time, your basic attacks heal you for 3/6/9/12/15 +20% AD health.
R: Fatal Strike: Violently lunges at a target, dealing 150/250/350 +100% bonus AD true damage to the enemy. This spell deals 150% damage to targets you have your Q active on. If this kills the target, then you recover 100/150/200 health instantly and all of your basic abilities' cooldowns are refreshed instantly.
