Level quest

Level quests are special tasks (quests) you can perform to cut the cost of
advancing an adventurer level in half.  For example, if a level costs 100
experience points without a level quest, it will cost 50 experience points
if the quest is completed. Level quests can only be completed before 
advancing to the level of the quest. To get information about specific 
quests, go to a pub.

Note:  exploration quests (ie explore 30% of the world) are completed by
exploring at least the number required for that level quest, then going to
a pub and typing 'explore'
