HP that are always added or removed. For example, a spell that heals 6 HP of damage would have 4 points of Hard Healing.
Damage or healing that requires a roll. Thus, if the same spell above healed 1d4 damage, it would have 1 point of Soft Healing.
Various things - such as area, damage or healing, etc. - cost one or more points. 10 points = 1 spell level.
So, let's scale a spell.
Components: A small bit of dead tissue
Casting Time: 2 rounds
Area of Effect: Special
Allows the caster to bind small bits of dead tissue to a wound, healing 1d6 damage.
Okay, 6 points of soft healing (1d3 is 3, 1d4 is 4, 1d6 is 6, 1d8 is 8). The range is 2 points. So, 8 points. A cantrip, but just barely. If we were to make it heal 1d6 +2, then it would be first level and a bit. (10.5, to be specific).
Basic point costs:
Soft Healing: d# = cost.
Hard Healing: 1 HP = 1.25 cost.
Soft Damage: D# + (D#/2) = cost.
Hard Damage: 1 HP = 2 cost.
Range: Self = Free. Touch = 2 cost. Other = 1 point per 5'.
