Path of Exile is an online action RPG, with a character you control an overhead perspective, you explore large outdoor areas and underground caves of dungeons, while battling against monsters and fulfilling quests NPCs to gain experience points and PoE Currency. There are some build tips you should know in Path of Exile.
There are 2 main defenses: Life and Energy Shield. As a rule of thumb, try to get at least +150% increased maximum Life from your passive skill tree into your build (To clarify, that is cumulative from +8%, etc., nodes. There are no gigantic +100% nodes.). Builds focusing on Energy Shield are not advised for newer players, as they are harder to gear and have several other difficulties compared to Life builds.
You need elemental resistances. An easy way to build up resists is through rings. It's a good idea to carry around different sets of resist rings and swap them out depending on the mobs you encounter.
Keystones are major, large passives that lie on the outside of the passive skill web. They have the ability to completely change the way a character plays, and builds are usually planned around which keystones will be taken.
When making new builds plan for about 80-85 skill points. You will reach this point around the time you complete Act III on Merciless and begin endgame content. No need to get all crazy with a 120 point build. By the time you have 80-85 points you'll have a much better understanding of where the skill points should be going. Also, this keeps your head from exploding.
In Path of Exile, with Path of Exile currency, you can exchange with other players for equipments, enhance your weapons, armors, duplicate Divine equipments and so on.
