Interesting, I didn't tried that but if it works it is really op, imagine Black Cleaver and PTA together, probably enemies will have negative armor (i mean not rally but that combination seems op for a duo ad lane) =))

Well to start with pros

You can literally cast Q on anything, ally or foe, even wards (I'm gonna even upload a video soon how to use wards Q)

I'd put it directly in guide but many people prefer that kind of chapters usually very short from what I noticed.

Her W is a delayed stun, but the stun is aoe (think about Zoe E but when she stuns you she also stuns everyone around you)

Her ult is extremly powerful as it gives shields and damage to everyone in it's way, the shields weidth is also ridiculously huge making it impossible to miss (the damage part can be missed tho)

literally her E, not much to say there that I alerdy didn't said in guide

Her stacking system (mist souls from passive) allow her to scale infinitely in both range and damage.

For cons:
Her autos are extremly slows and even if you build full attack speed she will still hit very slow.

She have no mobility, just a small bonus movement speed in her camo, but it's almost meangliess.

A squishy champion is a champion that can be easily killed not having a lot of hp, defensse or skills that allow a huge defense (for ex alistar ult reduce around 50% of all damage he takes), making them vulnerable to burst.
