Swap spirt rode for Mantle of Discord if they don't have hard CC. Sell boots when needed and grab another CD item such as soul gem or spear of desolation. Bumba's can work with this build if you want that over gem of focus. However, with the recent nerfs to it's pen it feels kinda lack luster.

Some people choose to not level her ult. While leveling her ult does nothing for the minions. However, with this build stance swapping is very common due to having max CDR 4 items in. With this build when you get spirt rode or mantel you are almost unkillable in a lot of 1v2 or 1v3 in mid game because of the defense provide from spirt robe along with the mitigation you get from her passive. Add a extra 15% mitigation if hit with a hard CC and you almost never die unless you are purposely running into their abilities.
