LoL 14.19 Patch Notes - All Rune Changes

Lethal Tempo is back with a new rework! We removed the previous one because too much of its power budget was in pure attack speed, which made other sources of attack speed redundant. If there other thing it granted was a tunable effect, this would have been manageable, but alas attack range is not that. After giving some time to re-adjust marksmen items, we are bringing Lethal Tempo back, this time with an effect that synergizes with your other attack speed purchases. 

• Tempo Change: Attacking an enemy champion grants a stack of Lethal Tempo for 6 seconds, up to 6 stacks. Each stack grants 5% Melee / 4% Ranged Attack Speed. At max stacks, attacks also fire a note that deals 9-30 Melee / 6-24 Ranged, increased by 1% per 1% bonus Attack Speed, as bonus adaptive damage.
• Tracking: Lethal Tempo now tracks how many of your attacks against champions are Perfectly Timed (Perfectly Timed: Attacks launched within 0.25 seconds of when your attack is ready after previously attacking a champion)

We're happy that Presence of Mind provides fuel for champions to whittle down their opponents but the current shape predisposes it to damage over time effects. This new model resores a similar amount of mana for most champions without being substantially stronger for very specific ones.

• Mana/Energy Restore: 1.5 - 11 (melee) / 1.2 - 8.8 (ranged) (based on level) or 1.5 energy per second for 4 seconds ⇒ 6 - 50 (melee) / 4.8 - 40 (ranged) (based on level) mana or 6 energy instantly, 8 second cooldown

We want Shield Bash to be more specific in its purpose instead of giving two relatively meek effects, so we're removing the invisible resistances buff and amping up the "bash" part of "Shield Bash."

• REMOVED Passive Resistances when Shielding: 1-10 (based on level) ⇒ 0
• Bonus Health Scaling: 1.5% ⇒ 2.5%
• Shield Scaling: 8.5% ⇒ 15%

We want to reduce mana restoration in runes that do not require champion interaction so we're converting the mana restoration effects of Biscuits health.

• NEW: Healing on Consumption: 12% of missing health
• NEW: Maximum Health Bonus on Consumption: 30
• REMOVED Biscuits no longer restore or grant maximum mana

We've changed Nimbus Cloak to feel punchier without being significantly more powerful by changing its flat move speed buff into a higher-intensity decaying one. The overall distance traveled is about the same as before but your initial burst of movement speed will be faster. 

• Movement Speed: 5-25% for 2 sec ⇒ 12-35% decaying over 2 seconds
