#
# This script will give experience to the "activating" player.
# It should be linked through the "trigger" event of an altar, or similar thing.
# Options are specified in the event object's fields.
# A key/value will be used to store in the player if she activated the item already.
#
# Available options are:
# - exp: experience to gain
# - skill: skill to add experience to. Can be empty, in which case exp is given to the general exp only
# - wc: what to do when the player doesn't know the skill:
#   - 0: give the player the skill
#   - 1: give player exp to total, no skill
#   - 2: player gets nothing
# - race: if set, the player can only use once this item.
