Welcome! This is my first guide, please give me tips and stuff. Anyways, sona has been my all time favorite support because at lvl 1-6 she can chunk squishies in lane. She is also very smooth because she can poke without receive any counter damage. She also has the luxury of not having to AIMMMMMMMMM! WIth the current GP5 items along with pick pocket, Sona gets a lot of money during laning phase. Her lane is very strong with pokes and heals. Her range is much farther than many supports and that advantage lets her be safe.
REmember to move back after u have fired q, dont want any funny business. ALSO remember to move around because sona should be hard to pin down after she gets boots and e.

Sona Absolutely must poke in lane. If she does not scare the enemy team or deal damage, she only has her utility left. And we dont want to waste her damage now do we. Remember to always stay behind minions at lvl 1 because minion chunk sona w/o armor. Also in teamfights, sona should be between tanks and adc and apc
For example:
TANK TANK TANK

SONA

CARRY CARRY CARRY

THen she moves foward when a tank initiates and ults-
TANk SONA TANK TANK

CARRY CARRY CARRY

When shes done with her ult, she moves a little bit back to where she was

TANK TANK TANK

SONA CARRY CARRY CARRY

WIth this formation, sona stays safe and gains maximum area for her auras.
She should be spamming q and w because those 2 aruas can happen at the same time for a breif amount of time. attack and defense is essential in fights.
