+1 heal prayers or +1 divine favor?

I can't really afford to get both and check them out... are there any experienced monks who can advise as to which of these two head designs I should get?

divine favor since it gives you or your target more health when u cast a spell. unless something like your healing breeze is 1 point away from the next health regen.

Well look at what staff, wand or focus item you are using and that should help you figure which one you need more.

+1 Heal.

i would also go for +1 heal.

+1 heal definitely.

There are just not so many divine favor spells you'll be casting all the time that it does pay off. By using the heal one, you get atleast the same +3 health to the spells (as every point of divine favor heals for another 3 points). But your alternate spells like healing breeze, healing seed and whatever get stronger.

Depends. Since we don't know what items your carry or which skills you use.

+1 Healing Prayers is better for full, 12/12 Healing Monk that just casts healing on allies/himself.

+1 Divine Favor is better for a monk also casting other skills on allies/himself.
