Below is a quick Final Fantasy XIV guide to surviving Eorzea:
*TP is gained by attacking with your two standard attack types or by being attacked and while not fighting slowly drains back to 0.
*MP is restored via items, a certain ability Disciples of Magic gain, finishing a Leve, or by touching an Aetheryte.
*Never forget about the Teleport option within your menu. You can quickly get back to any location you have visited with a full sized crystal. If you should want to cancel it, simply go into active battle mode (F).
*Always pay attention to the colored dot beside a selected enemy’s name in order to give you a clue to how your strength compares to it. Green and blue generally mean not much of a threat and yellow, red or above are very dangerous.
*Also remember that this dot represents your Final Fantasy XIV Class Rank against the enemy strength and not Physical Level (more about this is found later on).
*It can often be quicker to gain ranks or levels simply by heading out of the city and going on a killing spree. Leves are good for money and items, but not so much earning experience.
*Equipment has durability ratings. These are hugely high but do degrade over time and eventually will impede your abilities. These can be NPC repaired back up to 50% of your total in Limsa Lominsa or, if you have the required items, you can repair them yourself to a higher percentage than that. Generally you will not need to do this often, especially if you upgrade your equipment regularly, but pay attention to durability in your item list.
*When you die you will have a sickness which will impede your abilities to preform, it is risky to fight while this is active. The effect of this sickness lasts 3 minutes.
