Ashiinen's Harmony

You say the celestial name of Ashiinen, and the weighing scale melts at your feet. A magical aura with a 30 ft radius encompasses you, affecting yourself and all creatures inside. 

All hostile creatures that start their turn within the aura must succeed a constitution saving throw (Spell DC) or become petrified. At the end of it's next turn it can repeat the saving throw. On a second failure, the creature is turned to stone. Whenever a hostile creature casts a spell of 8th level or lower within the aura, they must succeed a wisdom saving throw (Spell DC) or the spell fails. Hostile creatures have disadvantage on melee and spell attacks against allied creatures within the aura. 

Friendly creatures within the aura (including you) become immune to all status effects, have a +2 bonus to AC and regain 2d8 hit points at the start of their turn. Friendly creatures within the aura (including you) have advantage on saving throws against spells and other magical effects . Additionally, when an affected creature succeeds on a saving throw made against a spell or magical effect that allows it to make a saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and half damage if it fails.
