I'll just add a little here, incase anyone might need it, because suprisingly i still see people asking what a certain token does even up to and past Pandoras Box.
Tokens:
Rescue: Prevents troop loss whilst active.
Inspire: Increases Hit & Shield by 20%
Storm: Increase Hit & Shield by 50%, but doubles attack cooldown (from 30s to 60s), generally don't use unless against your final enemy of the dungeon.
Faster: Halves move/action cooldown (usually from 10s to 5s unless you are on rough terrain, though u will usually see 9 and 4)
Sweep: Halves attack cooldown (from 30s to 15s)
Replenish: Halves cooldown for replenishing your troops.
Hopefully didn't miss any.
