Beast mastery 12+3

Ranger skills :

Fertile Season - Nature Ritual
Create a level 1-8 Spirit. For creatures within its range,maximum health is increased by 50-474 and they gain +24 armor. This Spirit dies after 30-78 seconds.

Symbiosis - Nature Ritual
Create a level 1-8 Spirit. For creatures within its range, for each enchantment on a creature, that creataure's maximum health is increased by 27-125. This Spirit dies after 30-126 seconds

Monk Skills :

Infuse Health - Spell
Lose half your current health. Target other ally is healed for 100-129% of the amount you lost.

Heal Other - Spell
Heal target other ally for 35-151 Health.

Aegis - Enchantment Spell
All party members are enchanted with Aegis. For 5-10 seconds, they have a 50% chance to block attacks.

Life Barrier {Elite} - Enchantment Spell
While you maintain this "Enchantment", damage to target other ally is halved. If your health is below 70~46% when that ally takes damage, Life Barrier ends.

Light of Dwayna - Spell
Resurrect all nearby dead allies.

Essence Bond - Enchantment Spell
While you maintain this "Enchantment", whenever your target ally takes physical damage, you gain 1 energy.

I´m still sorting out wich skills are best for this tactic. (And im not sure if its a common used one, I for one havent seen one yet.

The basic goal of this build is to be supportive to your party, giving them an huge amount of extra hp. And reducing the amount of damage they take..
