1-2 Extra Chained Energised Hits and 2.5-10% Impact on Energised Hits.
2.5-4%Charge Speed on low Overheat. Stacks up to 5 times.
This my Damnation Plasma-Gun build works pretty well even without the blessings.
Just make sure you have the feats which is the most important part.
The Attack Speed ,and Reload Speed perks on the main 2 weapons are the most important.
Due to this being a build that relies on reloading to get rid of heat in the plasma gun.
The main way I use the plasma gun is shoot with charged shots or regular shots till you are full on heat then reload to immediately get rid of all the heat.
I mainly use charged shots on Orgyns ,or Elites, and Basic shots for Ragers and below.
By doing this with the feats One after Another, and Tactical reload.
This is a 50 percent bonus Reload speed [After You Kill Elite Enemy], on the plasma that is a 9.4 second reload, this lowers it to 4.2 seconds.
The extra 30 percent reload speed from elite kill doesn't disappear till your next reload which is a nice bonus
With this build Crushers can be One-Shot in the head with volley fire from a charged shot of the Plasma Gun
[On Damnation]
The Attack-speed on the Power Sword allows for a heavy swing to hit the enemy, before they can hit you on Damnation, Where they are more aggressive.
The enemy will knock you out of your heavy attack if u don't have the extra attack speed on the power sword.
So have fun poping heads Plasma Man!
