Why apply Slow to a unit that's already Blinded?
To prevent a fast unit from acting on the next turn. Example:
My troops: a group of Druids and a group of Elves.
Enemy troops: a group of Phoenixes.
Turn 1
- Phoenixes fly towards the Druids.
- I cast Blind, move the Druids back, and skip the Elves' turn.
Turn 2
- I cast Slow on the Phoenixes and skip the Druids' and Elves' turns.
Turn 3
- I attack with the Druids, apply Blind, and skip the Elves' turn.
Turn 4
- I attack with the Druids, attack with the Elves.
- The Phoenixes die.
The battle is won, but if I hadn't applied Slow to the Phoenixes on the second turn and just attacked, the Phoenixes would have woken up on the third turn and killed me.
