This build is built around damage reduction and finishing the kill to get the elimination to reset all your skills.
Each Nade fired gives you 16% damage reduction that can stack multiple times
Each Nade fired gives you 8 ammo back so you can finish the kill before reloading
Tyra with 3 nades and double the ammo is pretty hard to deal with.
I would advise Nimble and Caut as priority picks.
You need that movement speed to get that line of site on fleeing champs to the finishing blow.
Remember though you dont have to get the kill to get the reset.
Speed will help you get to your team mates save them and get resets.
Try not to fight alone, while you can easily 1v1 a person it much better to jump on low health targets and kill two people that will reset all yours skills.
