The Healing over time seems to be 2d3 per tick. Tested with 25 positive healing power with 0 healing amp and got numbers 2, 3, 5, 6, and 7 on both 4 bard levels and 14 bard levels.
The initial heal seems to be 3d2 + 1 per Bard level happening twice on yourself, and once on allies. Can anyone confirm?
