I agree 100% that the spell needed to be without sustenance part from the start of 5E, but now it's next to useless.
Unless this is an underhanded slap to the life cleric 1 level dip cheese, then I approve.
Now it heals less than Healing word and it's, on average 5 actions in melee vs. 1 bonus action at 60ft range.
Yes, it has some utility that you can hand it out for stabilization, that's why it's next to useless and not completely useless.
10 berries at 1st level and +10 berries per spell level would work fine now that it has lost "feeding" mechanic.
Option one: Change it so that eating a berry either allows you to immediately spend a HD to heal yourself or lets you gain one extra free HD when you spend them during a short rest (like Bardic Rest). Keep so you can only benefit from one a day.
Option two: Each berry acts as 1/4 Supply, thus if you want to feed more than one person, you need to upcast it or roll very well.
Option three: Both. You can either heal
or eat a bunch of berries to get a Supply, but not both.
But yeah, I agree with you, Horwith. This spell has gone from OP to nothing anyone ever needs to take. Druids can already cast
cure wounds, and this isn't competitive at all. The only benefit is you can keep the berries for a day.
Option 4: Change the material components to 1 Supply, transform it into 2d4 berries, each of which heals 1d4 hp or, if you are at max hp already, give you 1d4 temp hp.
