Need to surprise or trick and enemy? Hiding your army? Need to take a vacation from the food trick?
You need to change the speed of your troops!
TO MAKE THEMREALLY FAST:
1. Conquer a wild, then bring back the conquering army.
2. Dispatch one scout with a hero to the wild.
3. Dispatch all other desired troops to the wild... they will merge with the hero+scout.
4. When you recall that troop from the wild, all the troops will return at the speed of the SCOUT, which can be very fast.
Note: you can do the same thing with a friend's embassy. Obviously you can skip the conquering part.
TO MOVE THEM REALLY SLOW:
(This one takes advanced planning!)
1. Conquer a wild, then bring back the conquering army.
2. Dispatch 1 rickshaw + hero to the wild with a time delay (1-499 hours).
3. Dispatch all other desired troops to the wild... they will merge with the hero+rickshaw.
4. When you recall the troop form the wild, all the troops will return at the speed of the RICK+BIVOUAC LAG, which can be very, very slow.
I forgot to mention... to move troops really slow, you can also use a friend's embassy... using an embassy means you don't have to worry about how many troops your target location can hold.
Another note: when slowing your troops down using a wild, remember that a wild can only hold (100,000)*(wild level) troops. So lvl 10 can hold 1 mil troops, lvl 5 can hold 500k troops, etc.
Implications of this:
If you delay 240 hours or more, any wild you conquer will be lvl 0 and unable to hold your army by the time you merge your troops.
How to get around this:
After sending your rick out, abandon the wild. Wilds randomly get a new level every day when the system resets. Reconquer the wild <24 hours before your rick arrives.
Obviously, this is why it's easier/better to use a friend's embassy... you don't have to worry about how many troops an embassy can hold.
