This champion build is meant to be a tanky support Nunu. Nunu has a great tank and can support very aggressively and quickly. This set relies on his ADC and the ADC's AD, so you should be sure to have an actual ADC-champion on your lane. Nunu can support by annoying the enemy ADC with his Attack Speed reduction and boost the ally ADC with Blood Boil, while he is also effective in later teamfights when Consuming jungle creatures while ganking and boosting every AD-champion with an extra Attack Speed. Nunu's ultimate is best to use in fights around objectives like a tower to defend, dragon, baron or a low-health cary.
