yes. lvl4 skills are important since they enable you to deal combos with related units. after they are all lvl4 raise them to 5.
thank you
How can you reduce the inventory when it is full
you can feed gulin with wild game, and you can store potions and material for making equipment in erland's bar. be careful not to have a full inventory since it can cause you to miss items that are needed for missions.
thanks
Where do I get a cpu key for the power core
you get it from ralf after completing his first mission. notice that if your inventory was full in this conversation it can cause you not to get it.
