Guild Wars 2

I want to try out the fractals but not sure how the system works besides that it has tiers and that you might need agony infusions as well. Any help would be great. As well as a good for Nerco in fractals as well. And no I main nercos its my best class and any other would not be good.

Those two sites have pretty much everything you need to know about fractals in general.

Generally necros are rather disliked in PvE content but have been steadily improved with some rather nice utility. Just try to improvise and see which skills could be useful in any given situation. Wells in general are a solid choice since they have good dmg to them and good utility trough boon removal, condi removal and blinds, spectral grasp, spectral walk, flesh wurm all have their uses and can make runs smoother for you and your party not to mention the new awesomeness known as corrosive cloud and it’s projectile block.

Look to the wiki for full details. Short form (and will change in the new HoT system):

A fractal is three randomly selected short scenarios in a row, followed by a random fourth. Your personal fractal level goes up as you do fractals at or higher than your current level. At levels 1-9 you need no special gear. After that you start wanting agony resistance to absorb the unblockable damage that comes at various points.

At higher levels, like, um, 30? There start being special “instabilities” that give extra handicaps to fighting in the fractals.

I can’t help you with Necro, I prefer Mesmer for fractals and dungeons.

Spoj-chan is the best when it comes to Necro.

Take a moment and read his guide: http://dulfy.net/2014/06/30/gw2-necromancer-pve-guide-by-spoj/

Are you NA or EU? I can help you out in fractals if your NA.
