Learn how to fight
You can't survive elder scrolls online (ESO) if you don't know how to fight. The best way of doing this is choosing a character with good fighting skills. This means that you should use a character with good blocking, dodging and interrupting skills.
The other thing that you need to know is how to operate your characters. The good side is that knowing how to operate your characters is easy.
For example, when you see your enemy winding-up for a killer blow you only need to double-tap a movement in order to dodge the blow. You can also right-click in order to take the sting out of the incoming attack then left-click to interrupt the next attack.
For you to level fast you need to quest. Quests tend to dish out more points and you are able to survive in the game. This means that if you want to survive you need to take as many quests as you can. The good side is that there are many tutorials that will teach you on how to quest effectively and within a very short time.
Enchant your weapons and morph your abilities
Once you are experienced in a given skill, you can morph your skill so that you can become more powerful and useful. You should note that although morphing is very good and plays a huge role in making you better, it costs you a skill point that you could have used to gain a whole new spell or ability.
In addition to morphing your skills, you should also consider enchanting your weapons. Using glyphs is the best way of enchanting your weapons and armor. If you can't get ready made glyphs, you should consider crafting your own glyphs. You can do this by gathering and combining runes.
Get ultimate ability as soon as possible
For you to be able to easily defeat your enemies you need to get ultimate abilities. To be on the safe side you should ensure that you gain the ultimate abilities very early in the game. You can earn the abilities by using unlocking spells and abilities that you meet in your journey.
