Path of Exile's Delirium league is around the corner. There's a lot to be excited about with this expansion, but just as much to worry about.

Every 3 months, Grinding Gear Games announces a new league for Path of Exile. This hardcore aRPG that harkens back to Diablo 2 is arguably one of the best free to play video games ever made.

Each league includes new enemies to fight, locations or Maps to explore, and hundreds of new items to experiment with. While each league has gotten more ambitious with items, "Delirium" takes this to a new level with Jewels that add new pathing options to your passive tree and Uniques that can enable new builds. Of course, there is an equal chance for things to go wrong with this league. Here are 5 reasons we are excited to Path of Exile's new "Delirium" league, along with 5 reasons why we're worried.

Every zone in "Delirium" will contain a mirror that will spawn a thick fog and, spawning from that fog, a horde of nightmarish demons players get to slay.

These nightmares have modifiers that make them more dangerous than your average monsters. For leveling, this is going to be an amazing change of pace for those who've mastered the 10 Act campaign Path of exile currency has to offer. For endgame players, this will also be fantastic to give Maps that extra risk and reward factor to them.

Since these monsters have powerful modifiers that make them tougher than most enemies, this can result in some odd difficulty spikes if Grinding Gear Games doesn't balance it properly.

Of course, players can skip interacting with the mirror altogether if they wish to not participate with the mechanic, but then they are missing out on the whole point of the league. Since these nightmares also give existing enemies powerful talents, it could make leveling a complete nightmare or, worse yet, result in only a small subset of builds capable of beating endgame bosses like the Conquerers or Siris.Tied to every league release is a fresh slate for every player, veteran or newcomer. Players will have to level characters from scratch with no items carrying over from Standard or past leagues.

Thanks to this economy refresh, items that would normally not be worth much are now highly sought after. The first week of a league, for example, players are looking to acquire good rare items with resistances and life upgrades to push harder content. Leveling Uniques gain value, and coveted endgame items that drop from tough bosses are worth an insane amount of currency. The rush to getting currency to make your perfect build a few weeks into the league is one reason why Path of Exile is considered one of the best aRPGs of all time.

With dozens of leagues released for Path of Exile, most of them have found their way into the core game in some fashion.

Most leagues have been added to the core game through a random chance of spawning in Maps, typically around a 10% chance to occur. While this was fine for a few leagues, we are now at the point where two to three events can happen in one Map at once. With the inclusion of Orbs of Delirium and the league itself including older league mechanics, it can get fatiguing having to manage half a dozen meta-game systems at the exact same time every Map.

One of the most enjoyable parts of a new league in poe currency is the new bundle of skills and support gems players get access to.

While only thee skills have been revealed so far, each seems to enable certain playstyles or make certain characters more viable. Take Blade Blast, for example. This skill will detonate remaining blades cast from skills like Ethereal Knives or Bladefall. Not only will this deal great damage to bosses, but these blades can also be manipulated for Animate Weapon characters, granting a consistent way of generating Animated Weapons during boss fights where there are no weapons on the ground to animate.
