Can Templar heal himself or/and others?
Templar have some spells that boosts his HP regeneration and provides additional protection, such as damage mitigation or greater defense and resistances. Also, there are some healing spells that use DP (Hand of Healing I); other like Empyrean Armor, which gives you some instant HP recovery and HoT effect; new Stigma, “Great Resuscitation”, added in patch 1.5, which will recover almost 2200 of your HP. You can alse redirect some of damage done to friends to yourself (Bodyguard).
