irelia is a mid game champ so if you farm farm and farm you will be beast if you get countred try to play passive farm under turret and call your jungler to help you. best counters for irelia are darius/jax/olaf when your playing agains darius try to play passive untill lvl 9 and you should runa nd atck speed item like wits end or statikk shiv and ask jungler to help you. when your playing agains jax try to be agresive at lvl 1-5 cuse you will lose trades when he hits 6 agains jax u should get phage and wits end and ninja tabi when you hit lvl 9 and you should be able to beat him and try to hit as many minions with your ult as possible. laning agains olaf is hard in early game avoid his E try to play passive till lvl 9 ask your jungler when you get wits end you should be able to beat him and if you bait his q try to engage oon a minion so your q is reseted. and remember irelia is the best at lvl 9-15 no1 can beat her at that level.

irelia"s team fights in mid game are so stronk you can burst the adc in 1 combo if your farmed well.

so yea that was my guide hope you like it i"m still trying to main irelia i told you everything i know.
