Path: Precision Slot: Keystone
PASSIVE: Attacking an enemy champion begins to build up a charge, basic attacks for ranged build up 1 charge, 2 for melee. Each singular charge gives bonus 10% movement speed for 1 - 2.5 seconds (based on amount of charges) upon stopping attacking become discharged, gaining movement speed equal to the amount of charges build up. Max charge cap at: 6

Path: Domination Slot: Keystone
PASSIVE: Hitting an enemy with abilities or basic attacking, creates a black area in their health bar for 1.5 Seconds (refreshed upon basic attacking). The size of the black area in the health bar is 40% of the damage that the enemy take from one of the cast abilities, area increased if a other ability does more damage then the previous. The max size of the black area is 40% of their maximum health, in addition enemies cannot be shielded or healed above the black area.

Path: Sorcery Slot: Keystone
PASSIVE: Upon casting an ability more than once increases the abilities damage by +5% (AD or AP, adaptive damage), reduces the cooldown by 5%, and reduces the cost by 5%. This effect stacks up to 5 times and lasts 5 seconds (refreshed upon casting the ability again) and the effect ends when no longer casting the same ability.

Path: Sorcery Slot: Keystone
PASSIVE: Obsorb the damage you take overtime, and when falling down to 25% maximum health gain a shield based on the amount of damage stored. (90 - 60 Second Cooldown) based on level.

Path: Resolve Slot: Keystone
PASSIVE: Each ally and the user of this rune will receive a seed that is placed in their inventory that grows over time. It is fully grown within 5 minutes, and can be consumed to instantly restore 25% of the champions maximum health (120 Second Cooldown). If the allies inventory is full, the seed will be automatically consumed upon being below 40% maximum health.

Path: Resolve Slot: Keystone
PASSIVE: Begin a game with an anchor that is placed in your inventory.
ACTIVE: This anchor can be activated to be placed in a targeted location and will remain there unless it is relocated by the user of this rune or an ally. Upon right clicking on the anchor, become untargetable and get pulled to the Anchor's location no matter the range, then this cannot be done again for 60 Seconds. The champion who has this rune, allows his allies to pull themselves toward the anchor as well.
etc. A keystone shouldn't shut down any champions kit. Also negates any Lifesteal runes, items and items that grant sustain

shield mechanic?
(or
)
if they happen not to go Conqueror or PtA. Almost every tank item has HP and is even stronger on Cinderhulk Junglers. I'd rather see a weaker version of this into a normal rune.
lantern on steroids. No Get-Out-of-Jail-Free cards, unless it's Stopwatch which roots you (stasis) and doesn't come online for 10 minutes. How would the ally relocate the anchor?
