Hello there.
DISCLAIMER : This is all my personnal judgement please feel free to discuss with me
I recently farmed siphoning to get power extraction (that we will now call PE)and i must say im pretty disapointed.
The damage is low, and the utility is futile, and already occupied by others spells, that are much more powerful.
Let me explain my thought here.
PE mean you are stamina, and using this in a melee range, right ?
If you are stamina you have 2 melee options : 2H and DW.
If you are 2H, the Major brutality buff is already provided in one of the most nice abilities in the game, rally.
So just use rally, and brawler for AoE, that gives you more dmg (Mighty CP), a shield , and a heal.
#I see you coming with "well yeah but you use 2 slots" : 2H users USE rally, so with or without PE, so we just swap PE for Brawler here#
If you are DW ... well just use Steel tornado.
Bummer.
This skill has a larger radius (does it even after patches ? i must admit im not sure) , more damage, have an execute throttle, and is easier to get.
Then you will say : yeah, but then you dont have the Major brutality buff, and i will answer : yes, but you dont need it, because how OP Steel tonado is, even without Major brutality, it still does more damage than PE.
This spell have a great potential and i really LOVE it. The animation is really great and overall i like it, but it poorly fills niches that are already filled with way better abilities.
Just compare PE morph to the magicka one (sry i dont remember the name right now).
PE : You gain a bit of damage (oh really ? waw)
Magicka one : You gain an OP sustain, and it adds Major Sorcery (?), that adds, how convenient, 20% spell damage.
Now tell me what morph really do suck here ?
Once again, i love this spell, but it needs a rework.
Just somethink like making it equal to the other one would be great.
Stamina stealing, dealing (DAMN) physical damage that would scale with CP, health stealing, Shielding, Applying A debuff. Literally anything useful would make this spell viable.
TL;DR : Power extraction sucks ATM and needs a rework.
Note that never i said buff. and i mean it. It needs a rework.
Thanks for reading, and please if you feel i've not noticed something important, let me know.
