I decided to create this guide after recently having a lot of success playing Nasus support.

This build works for two reasons, Face of the Mountain and Siphoning Strike. Nasus scales really hard mid to late game if he is able to farm stacks using Siphoning Strike. You need to get Targon's Brace as soon as you have 350 gold because it refreshes charges every 30 seconds instead of 60. Only use your charges with Q and save a charge to last hit siege minions.

In lane your job is to harass the enemy ADC with Spirit Fire and Siphoning Strike. It's very important to land Spirit Fire in tactical areas that will make the ADC miss on CS or move to a more vulnerable position.

Wither is such a great support spell. With 45% cooldown reduction it's like always having a mini Exhaust available. Use this as a gap closer or to peel for the carries.

No one expects a Nasus Support in champ select, so take advantage of this.

This game was ideal. We totally shut down their ADC which is what you should try to do every game.20 min FF

Updates in progress.

3/24/2016 - Updated runes. Testing of attack damage marks continues. These may not be necessary due to the way Relic Shield works for securing last hits. I will be testing if Greater Mark of Hybrid Penetration are a better replacements. I also moved 5 points from Intelligence to Precision. Input is appreciated.
