This should be just the same as Ornn top as you will be using the abilities just the same. Engage the ADC and try to lock them down as much as possible use all the CC to make sure then are dead from your ADC before they even have chance to kill yours. Brittle on the W will extend CC on the targets if used before auto attacking them. This can be useful if you are close enough to engage with Q,W, then E into the pillar to extend the knockup because if the Brittle proc, auto attack when they come down and that should be enough CC and damage for your ADC to finish them off. More than often though The combo will be Q, into E knockup on the pillar, W, Auto. ORNN MUST coordinate with the ADC. He can not finish off the enemy without follow up damage.
