Spectral Fear Build
Your build seems fine to me.
In fact i ve been using a similar build for quite a long time. 2 things i d advise changing, even thought they are mostly a matter of personal preference:
1. Soul marks for foot in the grave.
It can really help for shroud stomping/ressing or as a CC ‘dodge’ or (my favorite) to make your heal uninterruptuble. WIth spectral attunement, spectral mastery and 3 spectral skills you ll have a lot of LF regeneratio anyway
2. spitefull spirit for shrouded removal.
With rabid amulet your retaliation wont do a lot of dmg and removing one condition every time u go in DS can help now that putrid mark removes only 3 conditions. The basic reason i use shrouded removal though is to get rid of fears without using my stun break and with foot in the grave get immunity to them… In some rare occasions u can also remove ‘harmless’ conditions that are used to cover high bleed or confusion stacks/long burns and therefore be able to send these conditions to the enemy.
Other than that i prefer to use S. Armor instead of S. walk since it gives more LF per hit, but its just a personal preference, nothing more.
To compensate for the loss of swiftness from S. Walk I use WH or runes of the centaur isntead of CD runes. These runes only slightly reduce my overall dps thanks to the + bleed duration which makes up for the loss of CD.
Spectral attunement is very good in my opinion since it allows u to refill your LF bar quite fast making this build very survivable.
As for fear duration… i m fine with +50% since most of the time i get 2 ticks anyway. Going for more duration to get a 3rd tick out of doom while casting it at close range doesnt work for me usually because people stun break before the 3rd tick anyway.
