Description: The caster and all nearby allies receive the effect of the Greater Sanctuary spell, including the 2.5 minute timer. No other creature can detect the caster. Attacking or performing a hostile action will make the etherealness vanish.

Notes

Can only be cast once every 2.5 minutes, although resting or dieing will reset this timer, casting before this timer expires will still expend a memorized spell slot.
You will receive messages during the sanctuary period at 120, 60 & 10 seconds telling you the time that remains before you can recast.
Summoning a creature is not considered a hostile action, but a new hostile effect from a previously-cast spell is.
Those affected by greater sanctuary cannot be directly targeted but are affected by anything with an area of effect. Even Isaac's greater missile storm, manticore spikes, and hail of arrows will apply normally even though these areas of effect individually target creatures with their projectiles.
