Estranged son of the evil mutant Mystique, Kurt Wagner was raised by a fortune teller and grew up as part of a travelling circus in Germany. Using his unique physique and agility, he performed as the star acrobat for years until finally attempting escape. During this escape, Nightcrawler teleported for the first time, an event that lead to him being rescued from an angry mob by Professor Charles Xavier, who came to recruit him into the X-Men.Marvel Source
From there, Nightcrawler became a mainstay of the X-Men’s various incarnations, as well as other teams such as Excalibur. He uses his teleportation, expert swashbuckling and superhuman agility to defeat enemies quickly, but maintains a light-hearted and positive attitude and serves as a moral anchor for the team.
Your rotation for both single targets and area are the same and the basic rotation is:
Initiate with Infernal Brimstone > Flash & Grab > Shadowmeld > Dive Bomb > Flash & Grab until Dive Bomb is off cooldown.
Starting with Infernal Brimstone into Flash & Grab gets your One Step Ahead started and damage ticking in an area as well as pulling mobs into your Brimstone. Shadowmelding drops your aggro and causes the mobs to mill around in IB until you Dive Bomb for bonus damage. Flash & Grab is your spirit spender for both AoE and Single Target and does a lot for Nightcrawler's survivability.
Righteous Fury is best used in 3 second bursts to prolong the buff duration and maximize damage. I've noticed you're able to pop Righteous Fury, IB, Grab, Righteous Fury, Shadow Meld, Dive Bomb, Righteous Fury, Grab for an insane amount of burst damage. Mixing in an Obscuring Brimstone during Righteous Fury is also very effective.
All enemies will be Weakened and Vulnerable with this rotation and constantly moving between stuns, Dive Bomb and invisibility adds a lot of survivability. You want to keep constantly in motion and make sure to utilize teleport when you take too much damage. Teleport into Shadow Meld and Healthkit will keep you up even if you take a tick of Cosmic or get hit by a big ability.
Artifacts:
Pym's Shrinking Serum is a must. It gives you dodge, health and spirit regain. It's fantastic on Nightcrawler.
Crimson Crystal gives you more health and survivability and a good chunk of damage as well.
Advanced Super Soldier gives both defense and spirit which are two things Nightcrawler needs most.
Medallion:
