How to Level Efficiently
When you first start a character, you do not have a lot of skill points to beef up the damage of your main skill. To compensate for this, the game has sources of flat damage to skill damage via the affix “+x to x skill damage.”
For this build it would be, “+x to Additive Physical Damage” This is an extremely important affix to find on gear to make leveling easy!
As you play, you will find items with higher tier affixes that can add up to 1.5k skill damage! These affix names are in the item’s name so you can also know if an item has your damage type on it just by reading the item on the ground!
Affix names to look for:
Magic: 1-75
Arcanist: 75-150
Conjured: 150-500
Mythic: 350-1000
Rift: 500-1500
Next, we have additional affixes that also really help when leveling.

Zones to Farm
Outside of completing each act and moving forward through the campaign, there are zones you can farm for gear upgrade and xp. You do not have to follow this as some classes have a bit more power early and can directly skip to higher difficulty zones/dungeons.
Normal Area’s (1-50)
ALWAYS RUN ONCE AT START!
Act 1 → Outskirts of Inoya → Rat Den Dungeon
Until Level 16:
Act 1 → Woodhill Plains → Black Tower Dungeon
Until Level 24-30:
Act 3 → Dry Hills → Sand Cave Dungeon
Until Level 35:
Act 4 → Devil’s Breach → Devil’s Hole Dungeon
OR
Until Level 35:

Hell Area’s (60-100)
Once you reach Hell, any area will give you a lot of experience, but there is a quest I recommend you complete in Act 1 which requires you to kill 7500 enemies. The best dungeon for this is:
Act 1 → Outskirts of Inoya → Rat Den Dungeon
This zone has a lot of density! Be sure to update your loot filter and look for better runeword bases to either use or
What Quests Do I Do?
There are no required quests to complete each difficulty, but there are some that can give you supplies for early gearing.
Here’s the quests I recommend you complete.
Act 1 Normal -> 1 mid rune, rest low runes
A 15% movement speed charm
A 40% movement speed potion
(I only do this if my character does not have a good mobility skill built-in)
Act 1 Nightmare -> 1 mid rune, rest low runes

Act 2 Hell -> Few Mid runes
Act 3 Hell -> High Rune
