Rylo is a female yordle, wielding a shield and an axe. For aesthetics, the axe is rather large for a one-hander.
(Innate) Passive: Armor denting[]
Rylo's mighty axe hacks into an enemy when she strikes them, reducing their armor by 10/15/20 for 3 seconds. This effect has no cooldown and can be applied constantly, however it does not stack. The amount increases at levels 6 and 12.

In terms of strategy, a basic initiate and rotation in a teamfight would be to open with Aegis Leap, and use Rush and Valiant Vanguarde whenever needed, Rush for interrupting harsh channelling ultimates such as 
Katarina's blade lotus . And Valiant Vanguarde can be used to block burst damage, such as 
LeBlanc's double Q combo.
