NGU Idle tips for a noob?

So I've recently graduated from the Forest to the Cave of Many Things in adventure mode, and I was curious what the general consensus is for choosing gear. I want it to be as easy as upgrading to every clothing item and weapon the area gives you, so if this is the case please let me know, but I feel like if I change out all my forest gear, I will lose all my energy power. Again, maybe all the magic buffs are worth it, I just have no idea. Trying to think about the accessories hurt by brain even more.
