Summary
Lords of the Fallenis a soulslike through and through, and as such, it has a New Game Plus mode. For those unfamiliar with the mode, it’s when you finish a game and want to replay it while keeping most items and levels you acquired in your journey.
The most famous renditions of this mode add extra changes like it’s the case with Dark Souls 2, where plenty of new red enemies can be found. While Lords of the Fallen doesn’t add new enemies, it has its own features that mix the tried and true gameplay of New Game Plus in new ways.

You Can Start Over Without The Plus
Some People Don’t Need The Extra Difficulty
A New Game Plus journey can be harder or easier, depending on your build. It’s usually harder because enemies are stronger in one way or another, but for some builds, it gets easier for all the things you can start the game with.
If you don’t actually care about adding challenges and are just looking to do some leftover achievements, Lords of the Fallen lets you start a new game without adding anything new. While this might be boring to some, it’s more than useful for people looking to just fulfill their power fantasy and make the game a cakewalk.

You Keep Equipment And Levels
No Need To Find Everything Again
New Game Plus means tougher challenges, but only because you’ll be equipped to challenge them. Most of your hard-earned equipment will carry over to this new journey, as does the upgrade levels of your equipment, which includes your Umbral Lamp.
Speaking of levels, those also carry with you, meaning your build will remain untouched. As far as other unconventional items that you keep, there’s plenty, like:

Your Enemies Are Stronger
Par For The Curse In A NG+ Mode
It wouldn’t be a New Game Plus mode without stronger enemies, and they grow in power just as you expect. They deal way more damage, and their health pools make their original incarnations seem paper-thin. These differences only grow as you venture forth to deeper runs of New Game Plus.
Each New Game Plus run tends to be identified by the number after the plus sign.

Once you finish NG+, you may start NG+2, and so on.
Sadly, in terms of enemies, that’s about it for changes. It’s not that Lords of the Fallen doesn’t have some other tricks up its grimdark sleeve, but there are no new enemies in sight or movesets whatsoever. Still, if Elden Ring can get away with not adding anything, so can everyone else.

NPC Questlines Reset
You’ll Have To Meet Your Friends All Over Again
Since the world goes back to its initial state, it’s understandable that you’ll have to meet the NPCs all over again. This is often a good thing since achievement hunters can now finish quests that were locked out due to their initial choices. The three endings, for example, have widely different quest lines that block each other out.
Remember that you don’t have to start a New Game Plus cycle for the quests to reset. You can just do a regular New Game, as explained before. And if you got your ending but have some unfinished business in your current run, don’t rush ahead, or you’ll have to start all over again.

Boss Remembrance Aren’t Carried Over
Remember To Use It Before You Lose It
Boss Remembrances are among the most valuable items you can get from the hardest fights in the game. They give you access to plenty of items dedicated to their specific boss, from unique-looking equipment to awesome weapons. For New Game Plus, what carries over is that special equipment, not the remembrance itself.
A remembrance a lot of players miss is that of Adyr. It’s only acquirable when pursuing the Radiant ending, although it’s the easiest ending to get. Once you defeat the final boss, stay in your current run and go to the Shrine of Adyr, where you’ll be able to Soulflay Adyr’s Stigma.

You Can Unlock New Classes
They Depend On The Ending You Got
While the classes you may unlock aren’t exclusive to New Game Plus, they are where they’re mostly used due to their requirement. To get them, you have to beat the game with one of the three endings,each ending giving a different class.
These are the Radiant Purifier, Lord, and Putrid Child. They aren’t the strongest classes (except for Lord in some aspects), but they are different builds that nod at the hard work you put in to get those endings. If you’re not in love with your current build, having a NG+ run with one of these three can make the new journey feel refreshing.
You Have Fewer Vestiges
It’s One Way To Add Difficulty
While not much is added when it comes to enemies and their patterns, Lords of the Fallen does shake things up with its checkpoint system. You’ll have fewer available Vestiges for each New Game Plus run, and once you make it to NG+3, only the ones at Skyrest Bridge and Shrine of Adyr remain.
Something that many players dread in Soulslikes isn’t the difficulty of a boss but the run back to it after a loss. Of course, you’re not going to beat a tough enemy on your first try, but the exhaustion of having to cross the entire map for each attempt will remove some edge from your performance. While not exactly favored by the players, it’s a very different way to make New Game Plus an exciting challenge.
