This is not a guide, but a quick reference for supports to check for updated information on important aspects of the meta/game that are not immediately apparent. It is not designed to be read top to bottom, instead it's designed so that a support can use it as a quick reference for certain areas he's unsure of. If you have no idea what's going on then please read the entirety of the compendium.

A compendium is a collection of information gathered by those who have experience with that subject. The subject of this compendium is support, thus support players are welcome to provide information via comments/email and I will update them as I am able to do so. No single player has experienced everything in LoL, and ever will.

As a support, you are essentially the eyes/mouth of your team. In this position, you need to be able to inform and direct your team mates to provide optimal performance in game. A good support can make a world of difference.

This collection is champion independent. It is wise to be able to play a variety of support champions, so that you can fill in an extra role that your team composition might be lacking. Please look up individual champion guides, the people who wrote those have much more experience than I ever will with an individual champion.

Thank you for reading the entire forward, please enjoy and utilize the information held within to assist your team secure their next victory.
