League of Legends (LoL) Question: Liandry's Torment

Sounds awful. Ornn has almost no AP ratios and there is no way the item is worth just for the passive and that little bit of health. If you want to do more damage then Sterak's Gage and Trinity Force are much more reasonable choices.

I think personally that it's just a complete troll. Most of your damage as Ornn comes primarily from your passive, if you want to make full use out of it you're going to need to be tanky enough to proc it. Otherwise you're basically not a champion.

instead of liandrys try to get something tanky because his w does already hp% magic damage also he doesnt have a lots of ap scaling
