Skill Points are used to improve your core stats in Battlecry.
You can spend them to increase your maximum Health, Ammo, and Supplies. They can also be used to boost your attack and defense power.
For example, 1 Skill Point adds 10 Health, while 2 Skill Points increase your Ammo capacity. Other upgrades scale based on how many points you assign.
Using Skill Points wisely helps you stay active longer in battles and gives you an edge in combat situations.
