Hey there you LOL gaming fans/players this is a guide on lux support and how i like to play her it dosen't mean its the best guide but i hope you enjoy useing her as much as i do.

Ok so the runes i use are greater mark of potency for Marks greater seal of resilience for Seals greater glyph of clarity as my Glyphs and finally i use greater quintessence of potency as my Quintessence.
This rune setup gives you the early - late game survival whilst keeping your lane in check with harass.

OK so there will be some questions about my mastery's as I run her defensively with allot of mana regeneration and abit of offence when it is needed this build should help you stay in lane until about lvl 6 if you need to port back early don't worry its not the end of the world.

So the skill sequence i use is for early game zoning so your adc can farm without fear whilst maintaing a good amount of control to avoid ghanks from junglers the idea is to place your lucent singularity behind there minions to keep them out of farm range if used correctly you can harass the opponent out of farm for long enough to ensure a well farmed adc.

I personally use flash and exhaust the reason i use these to spell's is so that you are able to flash either in to a fight so that you can root the opponent into place or to use the exhaust as the help your adc needed to finish an opponent.
Also remember that both spells can be used in defence for your own survival and your adc.
You can also use clarity if you find that you are having mana issues or heal if your adc is getting hammered into instead of exhaust

Lux is a very aggessive support with alot of control early and late game she has the ability to control multiple targets at the same time for different angles however she dose have some mana issues in the early game so remember that but please give me some feedback on this guide as it is my first and iam open to suggestions.
