Please reply, I need your help. I've got at least 2 skill cards for spear but I can't use them. The game told me that "Can't use this skill card on currently equipped weapons"?

I've tried equipping different spears and it still doesn't work. Anyone know what's wrong?

Are you sure you're using Spear Skill cards? And they apply to the currently equipped weapon, the one you're holding on to. Having them in 1 of the 4 slots isn't enough.

I'm such a moron. Yes, I really have to actually hold the weapon in my hand in order to use the skill cards. Thanks for pointing it out for me.

Glad you realized it.
