Can Sanctuary save our party from a wipe out if I cast it on myself as a healer?
I am playing in a campaign where our DM's creatures often deal high damage to our PCs and occasionally we run into a large mob.
I want to know if I can cast Sanctuary on myself to deal with a wipe-out?
SCENARIO: I am the main healer. I have multi-classed as a Cleric (Disciple of Life) and Rogue (Mastermind), with expertise in Perception and Stealth.
If I think we are about to be wiped out by a large mob, can I cast Sanctuary on myself to discourage my being attacked, then use my Cunning Action as a bonus action to make a run for it?
The idea is that I will run away at full speed for one or two turns, using my movement and both my action and bonus action to dash.
Then I cast Enhance Ability on myself, roll for a Stealth check and return to the scene in hiding - ready to cast Mass Healing Word on the party before the 1 minute is up.
My hope is that most of the mob will have moved away from the scene, some will have tried to follow me and I will be able to get the party back onto their feet to finish up any remaining mobs.
Could I use Sanctuary to this effect?
Casting Time: 1 bonus action

You ward a creature within range against attack. Until the spell ends, any creature who targets the warded creature with an attack or a harmful spell must first make a Wisdom saving throw. On a failed save, the creature must choose a new target or lose the attack spell. This spell doesn’t protect the warded creature from area effects, such as the explosion o f a fireball. If the warded creature makes an attack or casts a spell that affects an enemy creature, this spell ends. (PHB p. 272)
