There are similarities to Imperial Mandate with this Passive. When you auto attack an enemy you will apply a debuff and deal bonus damage for the first application. If an ally uses an auto attack or ability to damage the enemy, it will detonate the mark dealing additional damage.

You can constantly refresh the passive buff if your ally keeps attacking the same target. There is no cooldown. You can apply 'fresh' stacks of Leverage if you attack a different unit and then go back to the intended target, this is similar to Miss Fortunes passive Love Tap .

The damage dealt is based of the targets MAX health, so you can get huge amounts of damage from the passive alone against high health, low magic resist targets!

Fires a hook out dealing magic damage, rooting the target. This ability is blocked by minions. If you land Handshake on a target, you can recast the ability in a small circle in any direction around the landing point of the ability.

On the recast you can 'knock' (counts as airborne) in any direction, including outside the original cast range of the ability. If you knock your target into a champion, they will be briefly stunned and take damage. The target you push, even if they are a champion, will not be stunned and will not take another instance of damage.

Tips:
The range of Handshake is particularly small and the animation windup is quite long and predictable. It is advised to use your E Loyalty Program, to slow enemy champions to help with this engage.

Once you have landed the first part of the ability you can run in a direction and recast at the same time. Particularly useful to get away from a gank.

Buffs an allied champion (including yourself). Increases the targets movement speed and attack speed when moving towards visible enemy champions. The buff's effectiveness is increased the longer the duration. This buff is refreshed if the allied champion gains a takedown (Kill or Assist) on the enemy team.
If a champion has Bailout and they were to 'die' they are instead restored to 100% of their maximum health and then start to take a huge amount of true damage until they lose all their health again. Generally, without taking additional sources of damage this should last 3 seconds.
If an ally gets a takedown in the burning state, they are instead set to 35% maximum health. This can only happen once per application of Bailout.

Tips: In a team fight, generally best used on a high damage champion. This is because we need them to score takedowns in order to 'revive' if they are put into the burning state, or allow them to snowball in the fight with the increased movement speed and attack speed.

Using this similar to a Zilean Ultimate is also possible, but mastering whether to save it for a target that is about to die vs using it earlier in a team fight for the boost is something that will take time and practice.

Launch Rockets around yourself, towards, and at a target location to shield allies & damaging + slowing enemies.

This is your bread-and-butter laning phase harassment tool, to set up engages and general protection in the middle of a team fight. There is an AoE around Renata on cast and at the destination. It feels weird to be 'hitting' your ally champions with rockets, but you are shielding them when doing so!

Tips: Works great with approach velocity to maneuver around minions to find the perfect Q: Handshake land!

Launches a slow moving, long range AoE cloud which if its enemy champions and/or minions will berserk them into attacking their own allies. The berserk debuff also grants champions hit increased attack speed.

Tips: A little bit on the weak side early on but amazing when you have more points in, as it increases the berserk duration.

If possible, use through a minion wave to get their minions to attack their own champions.

This ability is useless IF the enemy has NO auto attacking scaling champions. For example, if the enemy had a team full of ability power, the auto hits the enemy would be doing would be marginal at best.

This ability is treated as crowd-control so works with Glacial Augment and Approach Velocity. Anathema's Chains will also increase the duration of this ability.

This ability can be Cleansed / Quicksilver Sashed. It can be blocked by Yasuo & Samira's Windwall and Braum Wall
