Paladin Leveling
Here is your go to leveling guide for paladin, this guide will give you an overview of the common steps to take to achieve quick and efficient leveling while minimizing the hardships associated with running the game with no gear. If you want an edge on your leveling journey, please check out the following items. Lore, Stealth, Spirit Sword, Sigon Set, Eye of the Etlich. These will help you through your progress as they are low level requirement and high impact items.
The first step of any leveling start in the blood moor, kill monsters and spend your initial points into might, follow the path until you reach the Den of Evil where you can continue your leveling progress and complete the your first quest.
This quest will give you a bonus skill point that will help you continue killing monsters with ease by strengthening one of your skill.
Proceed to cold plains while killing the monsters you come across, pay attention to Champion Groups and Unique Boss Groups, those give more experience while being tougher. You can gage your strength and survivability while fighting those groups.
Follow the path in cold plains until you reach Stony Fields, when you have reached stony field, your next goal is find the "Stonehenge" of Diablo 2, this will get you started on your next quest: "Find and Free Deckard Cain".
To do this, you will need to follow the path until you reach the Underground Passage, be careful in there, the monster density is high and you will meet tougher beasts. Run through until you reach the exit for the Dark Woods.
When you reach the Dark Woods, start exploring until you find the Tree of Inifuss where you can get a scroll and fight your toughest opponents yet, Treehead Woodfist. Once you have defeated your opponent and grabbed the Scroll of Inifuss.
Now go see Akara and then head to the Stony Fields, go back to the "Stonehenge" where you can click on the stones. Click them in the right order and a red portal will appear for Tristram. There you will fight tough monsters and in the middle of the town, you will be able to liberate Deckard Cain. This is a good place to level and you can repeat Tristram as much as you want in new games (Online only).
Do Tristram until you are at level 14-15 where your strength will have augmented to a level where you can go through the rest of the game until Andariel with much ease.
Go back to the Dark wood, follow the path until you reach Black Marsh, once you reach Black Marsh, find the Tower and farm the levels, The Countess in level 5 will give you runes every time you kill her. Do this as much as you desire to stack up runes and make some runewords like Lore and Stealth.
Once you feel satisfied, move on until you reach the Tamoe Highland, there you will find the Outer Cloister and then the Barrack, in there you will find the Jail. Once in the jail, get to the level 3 and once you are there, find an exit to the Inner Cloister. This is where you will find The Catacombs, reach level 4 and the real fight begins. Go back to town to freshen up on potions and include poison potions, they will remove the poison effect of Andariel. Once you are ready, go fight, Kiting is usually the best move to do, attack then move out and go back in until she dies.
Act 2 has a similar pathing but no roads, you will need to stay close to the walls until you find the next. First you enter the rocky waste, there you will find the halls of the dead so you can go grab the Horadric Cube in level 3, you should find a chest in the middle of a room that contains your Cube. After you will need to find the Dry Hills where the Maggot Lair is, reach level 3 and kill the boss to obtain the Horadric Staff. When that is done, continue on your journey to Far Oasis and after that to the Lost city, in the lost city you will need to find the Valley of the Snakes. Entre the Claw Viper Temple and find the level 2. In the middle there will be a stash with the amulet Tainted Sun. Combine these 2 in your Cube and you will form the Horadric Staff in full. Go back to town and head top left of the village where you will find The Cellar Palace, head in there until you find the Arcane Sanctuary portal.
In Arcane Sanctuary, chose one of the 4 paths and follow the path until the end, at the end you will either find the Summoner or you will find a dead end, if it is a dead end, repeat the process until you find the Summoner. Kill the Summoner and then entre the Red Portal. You will then reach the Canyon of the Magi.
When you are in the Canyon of the magi, check your quest log where you will find the sign associated with the temple you want to entre. Once you find that Temple, entre it and follow through until you find a room where you can place the full Horadric Staff. This will open an entrance for Duriel, kill her and then explore the tomb, speak to tyrael when you find him and head back to town. Talk to Jerhyn in the top left of the map near the Cellar Palace and then Meshif who is to the right where the harbor is.
Act 3 first step is to head out of town, this act is the longest since the pathing is a lot more random. You will need to find the Spider Cavern in the Spider Forest for the Kalhim's Eye. After that you will need to get to the Flayer Jungle where you will find the Flayer Dungeon, head to level 3 to acquire the Khalim's Heart. Keep exploring until you find the Bazaars, there you will need to find the Sewers, in there find level 2 and you will find Khalim's Heart. Keep moving through the Bazaar until you reach Travincal, there you will need to kill the Council to obtain Khalims Flail. Once you have all 4 pieces, put them in your Cube and then use the weapon formed to smash the compelling orb, this will open the path to the Durance of Hate, find level 3 and then kill Mephisto.
Act 4 is quite simple, like act 2 you will need to follow the walls until you reach city of the damned, there you explore until you find the river of flame, explore until you reach the Waypoint. Once you have found the way point, you will be able to head to the Chaos Sanctuary where you will need to find 3 sets of seals, 2 per area, once you active the seals, a Super Unique will appear that you have to kill, once you kill all 3 and hit all 6 seals, Diablo will be summoned. Kill him and talk to Tyrael to move to act 5
In act 5, you will need to explore through the game, Frigid Highlands, Arreat Plateau and then you will be able to entre a cave called Crystalline Passage, keep exploring until you find the Glacial Trail, then you will need to find Ancients Way until the Arreat Summit. There you have to kill 3 Super Uniques, careful as they are extremely tough. They will give you about a levels worth of bonus experience once you kill all 3 of them. You can then proceed the Worldstone Keep, get to level 3 and then find the entrance to the Throne of Destruction. You will find a room where Baal will start summoning minions, there will be 5 waves of monsters, once you are done with them, head in and kill baal.
This is the full guide from act 1 to act 5 finish, repeat the same process for Nightmare and Hell.
