also about the boosters (maybe you won't find that info so easily)
- the skill point gift from a friend, gives directly 4% skills in a player of your team. it's auto
- the green booster,replenish 15% of condition to a player
- 5 reds are fixing an injury of one day. but if a player has an injury for 10 days, you don't need to use 10X5=50 reds.
15 reds are fixing any heavy injury. Just use them all at once (tabbing the red button 15 times)
- the blue pack gives +1 lv in morale. But if you use 2 packs at once, it maximize the morale to superb.
