Path of Exile is a Free to Play, Action Role-Playing MMO Game set in the dark Fantasy world of Wraeclast.
Path of Exile - ''It is designed around a strong barter-based online item economy, deep character customisation, competitive PvP and ladder races. The game is completely free and will never be "pay to win". Players can pick from six playable character classes, which each focus on either one or two core attributes: Strength, Dexterity and Intelligence.
Skill Gem System - Action RPGs have always been about two things: devastating skills and valuable items. Skills in Path of Exile are items - gems that grant abilities when socketed into equipment. A wide range of support gems allow the behaviour of skills to be modified. You can augment your Fireball to chain from enemy to enemy or split into multiple flaming projectiles. Up to five support gems can affect a skill at any time. Because gems level up independently and some are hard to find, they can be very valuable in trade.
Passive Skill Tree - All of Path of Exile's character classes share its vast passive skill tree. Starting at one of six distinct locations dictated by their chosen class, players can focus on the core specialities of their class or travel across the tree to build complex combinations of skills from various disciplines. Scattered across the tree are Keystone passives that drastically alter the way a character is played. Resolute Technique removes your ability to get critical strikes, but also prevents enemies evading your attacks. Necromantic Aegis grants the properties of your shield to your minions rather than to you. Combining these passives with clever item and skill gem choices allows players deep levels of customisation.
Path of Exile is completely designed around items. Any game system that can be itemised with random properties has been. The flasks are persistent items that have mods. End-game areas can be found as Map items that have mods altering their challenges and rewards.''
