issues with spirit not working properly

issue is i have more then enough spirit at around 120 or so as a druid and it will not let me use bark skin and herald of ash at the same time and that is with no skill gems attached

Do you have taken the Lord of the Wilds passive node?

"

50% less Spirit
Non-Minion Skills have 50% less Reservation Efficiency

Look also in Lord of the Wilds wrong spirit costs.

Ok, lets say in the game you have 100 Spirit.

You take the node that halves your spirit and doubles costs. BUT you use a sceptre with +100 Spirit.

You get 50 from default and 50 from the sceptre (since its halved). Giving you a total on 100 Spirit again. (kinda pointless BUT you also get the buffs from the sceptre)

I have the 50 default (halved) + 20 (halved) on my armor + 60 (halved) on my sceptre) = 130

The summon wolves skill costs 60 spirit, Fire aura is 60 (doubled), +Clarity gem is 20 (Doubled), Sceptre aura/skeletons is free.

For an extra skeleton it will cost 47 (+50%, No idea why)

With the sceptre skill I get 130 (And double costs), Without the sceptre skill (and no sceptre) Id get 100 + 40 (armor)

Without that skill I'd be able to have Wolves (60), Fire (30), Bark (30), and Clarity (10) and regen (10). AND another necklace that can add up to 50 (Giving me space for another aura)

So all in all, its not realy worth it on its own (unless your doing minions) but I also get the buffs from the sceptre. I can get sceptres with more Spirit. I just dont have one right now.

Now that I've done the math, its NOT worth it at all.
