Fix tooltip on Wretched Hag's ult and SotM

[Q]

So the tooltip shows the minor increase in damage but not the reduction in cooldown (which is the only real reason to get SotM on Hag).

Cooldown is 135 at all levels without SotM. With SotM it's 120/100/80 but the tooltip does not reflect it.

Confirmed.
