I just got it and have yet to use it. It seems very underwhelming. I have another legendary, Mossire’s Mukluks that gives +30% movement which works very well with the helix Residency(+5 biosynthesis duration).
My current epic that I would have to change out is
+14% heal power
+9.8% healing recieved
-42 Shield Recharge per Second
And it only costs me 756 to activate, opposed to
+12% Heal power
- 3.6% Movement speed
Miko Only: Add 50% of kunai poison damage dealt to your next healing beam pulse
Even without texting it, it just doesnt seem worth it.
