If you look closely, it says "Cost: 100% of maximum health", as in the fact that Shanoa dies, which should be changed to current health now that I think of it. The damage dealt is at most 1000 +300% AP.

And as for the name being the same as Renekton's ult, I didn't think about it, but the name is taken from the ultimate glyph from the game Shanoa is from.
