The cost of Tempest Rush/Tailwind is 10 Spirit and the Spirit Regeneration i have is:
Exalted Soul 1.00
Chant of Resonance 2.00
Right Hand 2.48
Left hand 2.43
Which added together results in 12.03 Spirit Regeneration, the Detail sheet says 13.47 but where extra 1.44 SR is coming from, I have no idea.
But despite I'm having plenty of redundant SR, my Spirit keeps depleting, so I switch to Tempest Rush/Northern Breeze, which lowers the cost of TR to only 8 Spirit, but it still depletes my Spirit, albeit slowly.
What am i missing?
