Splitting up
Four dwarves in four tunnels is four separate fights, and none of them can be revived. Stay within reach.
Hoarding nitra
Nitra spent late is worth less than nitra spent early. Call the pod when the team is low, not when someone goes down.
Ignoring the extraction
The pod timer is a hard limit. Start moving before it starts counting, not after.
Solo resupply
Calling a four-charge pod alone wastes three charges. Call it as a team.
