50 points for help! Legend of Rocky Hero, a series of questions about the shield lady.

I'm playing Shield Lady. It's my first time playing it. I'm currently level 23.
I don't like PK, I just like dungeons.
Ask the following questions,(5 points per question)
1. Do I have to learn all the skills on the skill bar? (I heard that skill points are unlimited?)
2. If I don't have to learn all of them, what skills should I learn? If it was an active attack skill, such as counterattack, Everlasting Fragrance, and the like (those that took the defensive route)
3. Currently, I have learned Defense Level A, Shield Level B, Defense Enhancement Level C, Heavy Armor, Plate Armor, and so on. I have first learned the equipment and personal attributes route. I have not learned any attack skills. I want to max out one and add another. Is this a good way to add? Or could it be that a certain skill was upgraded to C or B and then upgraded to something else? Sequence?
4. Is it better to train as a Paladin of Light than a Paladin of Dark if you take the defensive route? As the dungeon's defensive shield lady. (Does a Paladin of Light absorb damage while a Paladin of Dark deals damage?)
5. Bonfire, Meditation, Potion Enhancement, Cloth Armor, Intelligence, etc. Is there a need to add these skills? Why?
6. Is it better for the Shield Lady to specialize in the sword or the hammer? My sword is only at E rank and my hammer is not out yet. Should I max out both? What level was suitable?
7. As a shield lady who walks the path of defense, what's the difference between holding a hammer and a sword, other than the difference in attack power? What weapon was the best?
8. Do I have to max out the levels of Heavy Armor, Plate Armor, and Shield? What was the difference between a big shield and a small shield? (Why do I see in the posters that those with big shields are all holding swords and those with small shields are all holding hammers? Is there a difference?) Why did they have to do this? Then should I take a big shield or a small shield?)
9. What's the fastest way to farm skill points? I don't have any coins now. I can only farm small dungeons (which don't require coins) but I only get about 20 skill points at a time. How can I farm skill points quickly? I hate that my skills are too slow.
10. How to Earn Money Quickly? I want to earn more money to buy equipment in the later stages (I don't like to make my own equipment, I like to buy the finished ones), but the equipment in the later stages is in the hundreds of millions. It's too expensive. Then what's the fastest way to earn money? According to my level, of course, I can also make a budget according to my leveling route...
The above 10 questions, please understand this game, understand the shield lady friends to answer, thank you,
If you don't understand, please don't mislead me. I don't accept copying. 5 points for each question, a total of 50 points. Please answer seriously. Thank you.

Answer 1

He could feel a strong force blowing past his body, and he could feel himself being blown away. This made me hear a voice that was very unfamiliar to me at the time.

The voice was: " Hello, I am the noble thing in the legend of Loki the Hero. I am a precious elephant. I am an incomparably powerful warrior. I am a hero who saves the world. I was the most expensive elephant in the world at that time. I will accompany you until the world develops into a better place."

When I heard this voice, my surprise was indescribable. I was very surprised because this voice told me that we have a powerful mission and that we must save the world together.

This voice tells me that we must go to a mysterious place where an ancient spirit hides an extremely powerful force. We must find the hidden spirit and take its power to achieve our goal.

When we create a new world, we must have great power. This is our dream and our mission. We must move forward together and work hard for the beauty of the world.
