This isn't exact, but it's roughly

5 det = 1 mind = 1.5hp per 400 potency cure. Post above me holds to this formula rather well. This gives you a general idea of effectiveness.

Spell speed is always 10 SS = -0.01 seconds off the GCD, but scales higher on higher casts, and lower on lower.

Spell speed is always 10 SS = -0.01 seconds off the GCD, but scales higher on higher casts, and lower on lower.

Slightly more accurately, every 26 spell speed above your base of 341 reduces casting time and GCD by 1%. So for example 471 SS would mean 2.37s GC and 1.9s casting time for the 2 main cures.
