You’re not a support. You’re a menace with a warding item.
River Jax doesn’t play lane — he visits it. You exist to tilt the enemy jungler, midlaner, and sometimes your own team.

Lvl 1:

If your ADC can stop crying go all-in. Most of the times it will work.
Stay in 3rd bush in lane, wait the enemy, and suprise when they think you leash.

Lvl 3:

Time to roam. Leave lane, enter river, and start your pilgrimage. Mid, jg, scuttle — all are valid sacrifices.
Make sure to stack your sup item after each gank you do.
Yes, that means steal your Yasuo's xp and make him cry too.

Mid Game:

You’re basically a second jungler now. Ward, fight, steal XP, repeat. Split when possible, punch whoever looks squishy.
Try to secure all the kill, you need gold to snowball.

Counter Strike (E) = anti-gank button.

Ward bush, leap in, bonk, leave — repeat until someone dies.

Don’t listen to pings unless they’re question marks.

Always press no. (Wait for someone to go afk if things turn bad)
