playing sion suport is troll. it can work but its like picking.. sion instead of naut or leona. however its fun and can catch people off guard especially in a decent matchup. picking spellbook + relentless gives you a strong roaming power, your high base damage + smite from the spelbook means you can easily get enemy jungle camps, but giving up smite for this instead of objectives double smite is kinda troll but still possible.

i want to preface this by saying this is a genuine ass pick (duh). if you dont win lane and omegasnowball early, your chances to lose grow more and more as the game goes. maybe im just a bad player, but i find that if you dont win by minute 20-25, you might as well genuinely ff. you get outscaled like hell, as youre basically playing vegan sion.

im also a low elo noob so i guess this entire guide might as well be entirely irrelevant !

your goal is to bully the lane as much as possible, because if you dont win early you become useless. never leash, if you see ur adc trying to leash gently try to ping them away, but dont pry and spam, so they do not get tilted, as they already probably are from your pick. stand in far bot lane bush level 1 and try to get an early charged Q for free. depending on your comp you can of course invade the enemy top or bot jungle for a kill. if you hit medium to full charged Q, enemy bot wont be able to follow up for free, so you now get a vital free lane advantage.

bush control is imortant, so its recommended you take sweeper lvl 1. look for Q's as much as you can. your E and ult are pretty much sole engage tools. this is why taking approach velocity is so important. you are melee with no dashes.

your W passive is not really working when you play sup, but to make best use of it, try to use your support item stacks on minions instead of champions, and prioritize cannon minions, as they give more health. this way you will get more health, but less gold. and dont forget that you can kill enemy jungle camps fairly easily.

try to roam whenever you can. and if your adc is very ahead and plays something long range and safe, you can try to roam off your timers, but be sure to communicate it and actually get something from the roam. this is where tp from spellbook is very useful. roaming itself is very important (duh) for this strategy. you have to get other lanes ahead, and be on objectives. if you are able to see an enemy comp and can say that you cant lane and cant roam, it might be best to pick something more "traditional" (yuck).

an example of a masterful 6pek style roam

sion has a passive (shocker), but you will end up not utilizing it intentionally. unless you play on a zimbabwean supersever once and a revelation comes to your mind, or just watch enough baus streams. you can do an inting sion botlane. however, do not force it with randoms in soloq. your adc will likely get lost, not knowing what to do, not following up, then you will get nothing and your team will flame you, and if it happens often enough you might actually get banned.

when playing with randoms, and you see that youre getting ganked and you you know youre unlikely to get out alive, it is often best to try and land your CC and then die immediately. if enemy has low enough health and they used their CC's, you can very often get a kill or two (or a flash, or they just get out alive anyway...). some people simply forget they are playing against sion and disrespect the passive, then die.

when you play duo, esecially with draven or other strong pick, you can "intentionally look for a death angle"(c) and get your adc free double kill and a free lane. and the opposite applies, if you are losing lane, both low on health, wave is about to crash and enemy bot is only about 50-70% health, you can look for a death and either kill, or burn their flashes and get your adc uncontested farm. but if you play against something like cait lux (demon lane) or they have a lot of cc then its very tricky, and might actually be impossible.

basically, see for yourself. if youre not sure then its okay not to use your passive intentionally, but i want to say its okay to make mistakes because thats how you will learn.

i also cant stress enough how many times enemy lived on 1 hp from my passive and you just cant reach them without phase rush and youmuus.

thats pretty much it.
