I have a Life Cleric who would like to help the party's "Big Guns" be more effective in combat, but do so in a way that (hopefully) doesn't increase my healing load.
The Sanctuary spell forces enemies to succeed on a Wisdom save in order to attack me, unless the spell ends:
If the warded creature makes an attack, casts a spell that affects an enemy, or deals damage to another creature, this spell ends.
The Help action says I can:
[...] aid a friendly creature in attacking a creature within 5 feet of [me]. [I] feint, distract the target, or in some other way team up to make [my] ally's attack more effective.
It appears that I could cast Sanctuary on myself, wade into the melee so my more effective touch heals are where they're needed most, AND use the Help action now and then to give advantage to some of my party's attacks.
Am I correct, or would using the Help action be deemed as an 'attack' that would end my Sanctuary?
