Hi all! I have a couple questions about combat, as per the title. 

• Is it possible to have skills that target random enemies and
• Is it possible to level up the damage of skills alongside the heroes? I can see that it's possible to unlock new skills as the heroes level up, but I don't want previous skills to become obsolete because their damage output is less significant. 

I'm new to coding and game making in general, so, while I suspect it's something to do with variables, I just don't know how I would go about it. Any help would be appreciated, thanks a bunch
