nOOb question # 11: Keeping track of killed units

[Ish]

If you prepare to cast ressurect and hold it over your troops it gives the amount it will ressurect, and a percentage.

If the percentage is 100% that means that more creatures in that stack have been killed than the spell can ressurect. If for e.g. it says 70% it means it took 70% of the spells power to ressurect that stack to full numbers.
