Poppy's ult makes her do 40% more damage to her target, while not being able to targeted by anyone else than that champion. It's almost as strong as Kayle's shield now is, but with the bonus damage, and if you use it at a burst mage who just used his/her burst, then it's even better, because they don't deal any real damage with basic attacks, so you are almost immune to damage.
