If you use only 1 up, you'll get 8(1.5)=12 relics. You can use these relics any time to give any main team player an extra upgrade per relic. So you could give yourself 6 extra upgrades next round, your Lt. 3 extra upgrades, your Berserker 2 extra upgrades, and your SB 1 extra upgrade, or everyone gets 2 extra upgrades, or give yourself 3 extra upgrades for each of the next 4 rounds, etc.
