Getting started in Expert Mode
Expert Mode is an extra-difficult mode introduced in Terraria version 1.3.0.1 which makes the following happen: Now, if you think you're ready for the game, then let's jump right into the action.
 * Enemies have twice the health and damage output but drop more loot
 * Some enemies have modified AI to make it more difficult
 * Bosses have scaled health depending on the amount of players and some have revamped AI
 * Regeneration and vampiric healing is less effective
 * If you're a Softcore player you lose 75% of your coins rather than 50%, and enemies can steal any dropped money they walk into
 * You stay dead longer
 * Defense is revamped to become more effective than in Normal Mode

Day 1
The beginning spawn is like any other spawn; you will be in a forest with the Guide next to you and your inventory has Copper tools (if you made a new character). Now, you should probably go cut down some trees the moment you hear the sound that plays when the loading screen transitions into the game. While you're busy cutting away trees, kill any Slimes that come near you as you'll need their Gel (and they do pack a punch with Blue Slimes dealing 14 damage and having 50 health). Survey the land around you; if there is any sign of red or purple grass and trees then steer VERY CLEAR of it. Eaters of Souls and Face Monsters can kill you in two hits. Look for any Iron or any higher tier ore in the ground too, as they'll benefit you in the early-game, especially if there's a lot of it near the surface. Be sure to get Stone as well when you're getting ore. Check for chests on the surface, as you'll find items like Recall Potions and a decent amount of money from pots if you want to get the Merchant in the first day. Make sure to take any chests you find with you so you don't waste any Iron or Lead.

Once you get around 150-200 Wood, build a Workbench if you haven't already and a small home (whether you built it with wood or in a cave, it doesn't matter) and in addition to the Workbench, build a Furnace somewhere near your establishment (20 Stone, 4 Wood, 3 Torches) so you can make some bars out of any ores you gained. If you've got enough ore for items, be sure to get the pickaxe first (unless it's Copper or maybe Tin, then use it on a broadsword) as it'll help you the most when it comes to saving time. If you've got the time and the money, build a second house for the Merchant to appear and place a Campfire anywhere near your houses. If you have a sword, bow and other combat items

Before night ends, you should have probably gotten these:

If you happen to find uncommon or rare accessories (like an Aglet or maybe even Hermes Boots) then immediately equip them as they'll most likely improve your survivability especially if they have modifiers such as Warding or Violent.

Night 1
Once it gets dark, that's when Expert Mode shows its true form. Hopefully your home is secure and you can defend yourself if necessary, as Zombies and Demon Eyes will appear all over the place like they would in Normal Mode. The difference now is that zombies now have health near or at 100 and Demon Eyes usually have 120 now. In addition, some Zombies will hold one of their arms and will do even more damage from a longer distance, making them more difficult to dispatch at close range, and the poor knockback and shooting speed of a bow against swarms proves to be ineffective. A good idea is to get on top of your house if it's short enough for you to get up and see/shoot the zombies and tall enough so Zombies can't reach you. That way you only need to cope with Demon Eyes first. Another method is to just place a hole in the wall of your house or a barricade so that you can shoot through it without having to worry about zombies coming in and threatening you.

If you have a Merchant, you can buy more Arrows and Shuriken from him if you run out of either. Be sure to kill every Zombie as they can pick up money dropped on the ground and despawn while holding it if they get bored and leave, essentially losing potential funds. Demon Eyes can do the same but they don't hit the ground often enough for it to happen, though they are harder if not impossible to stop once they escape if it becomes day.

Once night ends and the zombies are shambling back to their graves, sell any unneeded Shackles (preferably the ones that don't boost defense or attack) if you have the Merchant unless you want to keep them for later if you want to craft them with other items once you get the Tinkerer.

Preparing For Underground
Now, the underground level is where things get a little less tense, but you gotta make sure to watch your step as there will be plenty of Black Slimes and Skeletons stalking you. The main difference here is that Skeletons are now capable of throwing high-damage bones and Jellyfish can become electrified and be invulnerable for a brief period. Pots will yield more loot than usual. As you get better ores, keep upgrading your pickaxe (Tungsten is the threshold as it can mine Meteorite, but a higher tier pickaxe is always better) and be sure to find any reserves for a sword or bow. Prioritize Gems as you'll want to get a Grappling Hook as soon as possible since you only need 15 of a single Gem to make one at an anvil (the Amethyst hook is the only Gem hook with a worse range than a standard Grappling Hook). If you're a magic user or are planning to become one, save some Gems for a Gem Staff as well as the corresponding ore. It is preferable to use Amethysts and Topazes for these as they only require Copper and Tin, respectively.

Be sure to light your path if you want to survive down there, especially if you don't have a Magic/Ice Mirror yet.
