About the dervish primary.

Have you ever arcane echoed shadow form? Well check out it's despriction

For 5-17 seconds, all hostile spells that target you fail and all attacks against you miss. When Shadow Form ends, lose all but 5-41 health. This is an elite skill.


The thing is though if you arance echo it to bascially renew the enchant you do not go to 41 health or whatever until it actually is finished.

Now then, the description of the dervish thing,

Mysticism (PRIMARY ATTRIBUTE)
Whenever an Enchantment ends, you gain 3 Health for each rank of Mysticism and 1 Energy for every 2 ranks of Mysticism.

If the enchantment actually doesn't "end" you won't get the energy, stone daggar spamming won't work then unless it is bugged.

So reversal of fortune spam could still work since it would end, but i don't think simply renewing the enchants would work unfortunally.

So finding enchantments that end very soon would be very beneficial if you are not a /mo to CoP them all.

David Lionmaster was the first one that i saw mention the shadow refuge combo sounds like one of the best self heals for a non-healer.

So anyway, sorry to put a damper on some of your plans, but from what i have observed things will work out how i said.
