Stand Evolution

You have continued to train your stand and have unlocked a new ability. You may choose one of the options below, or come up with your own (at your DM's discretion)

Time stop- Once each time you summon your stand, you can cause your stand to stop time for 6 seconds. In this time you may take another turn, automatically succeeding on any attack roll or other roll (as allowed by your DM). You may also use it as a reaction to move out of the way of any attack or any physical saving throw.

Healing- 3 times each time you summon your stand you may use an action to use your stand to heal your allies. Your stand can cast Mending at will, and can heal any creature it is touching by 1d6+4 hp.

Explosions- When your stand hits a creature with an attack,  all creatures within 5 feet of the creature must make a DC 16 Dex saving throw. On a failure, the creature takes damage equal to half the damage dealt to the first creature and is pushed 5 feet away. On a success, the creature takes 1/4 the damage dealt to the first creature and is not pushed away.
