General Information
Great Heal Excerpt comes with one use per attunement slot. It requires 14 faith to use. It has a fairly long casting time during which the player is vulnerable, and heals a large amount of HP.

Overview
Great Heal Excerpt fills a very small niche. Per slot, Heal recovers more HP; in terms of use, Great Heal recovers just as much HP but comes with three times the uses (in exchange, it has a higher faith requirement). Using humanity to heal is both faster and heals more. Therefore, it is really only appropriate to use Great Heal Excerpt when

1) the user needs to recover a lot of HP, but still has the time to pull off a healing spell

2) has not met the faith requirement to use Great Heal and

3) does not want to use humanity for healing.
