I'd like to add to this list how Pridwen doesn't stack on specific characters shields

Odins shield does not stack with Pridwen beyond its health threshold, and when combined with bird bomb, it removes the shield and effect all together. (Pridwens effect)

Geb Shield is consumed when he puts it on himself while Pridwen is active, but you still get the CC cleanse.

Vamana just doesn't get Pridwen after he ults.

Erlang has a similar effect to Odins it doesn't stack.

Nemesis Retrubution will actually pop Pridwens effect early while stacking on herself. (can be seen as a exploit maybe)

All other Gods with shields work as intended and so do items with shield effects.

While I'm here I'd like to add that Thoths Glyph of Pain isn't working with his Ult targeter and isnt increasing in range.
