DDO information project/Skills

This is similar to the information project about spells. Check it here to know how it works.

Haggle
This appears to be how the prices are worked out in the taverns


 * Cost = Base Value * (1.2 - (Haggle * 0.006))


 * Sale price = Base Value * ((40 + Haggle) / 400)

Heal
When resting at a shrine, the amount of HPs healed is equal to 10 + 3 * (level + maximum score in heal of a nearby party member)

Confirmed by developer David Eckelberry in this post

Note that this does not apply to warforged which use the repair skil.
