This is what I believe happens; enchantments are in effect a percentage modifier on one's damage (both types, not just magick) that can vary depending on whether the targeted enemy is weak, null (for lack of a better word) or resistant to it. In terms of powerful, they go:

bare elemental enchantment from a weapon (e.g., Ascalon's holy property)

Boon

Enchantment (MK buff)

Affinity

Trance

Pact

Invocation

The tradeoffs for Trance/Invocation's party effect and greater percentage damage bonus is that their duration is less than that of an Affinity or Pact.
