Villager Levels

Trading

Levels	Novice, Apprentice, Journeyman, Expert and Master.
Experience needed	Apprentice at 10, Journeyman at 70, Expert at 150 and Master at 250 villager experience in total.
Experience per trade	Each use of a trade gives the villager a fixed amount set by that trade, between 1 and 30. This is separate from the experience the player receives.
Trades per level	A villager starts with 2 trades and adds 2 more at each new level, picked at random from that level's list, for 10 trades at Master.
Levels with one trade	A level whose list holds only 1 trade adds 1 trade: Butcher at Expert and Master, Fisherman at Expert, Shepherd at Master, Toolsmith at Master, Weaponsmith at Journeyman and Master.
No repeats	The 2 trades added at a level are always different from each other.
Level up	The villager levels up the moment its experience reaches the next threshold. The new trades appear at once and the villager gets Regeneration I for 10 seconds.
Player experience	Every trade drops 3 to 6 experience points for the player. The trade that levels the villager up drops 8 to 11.
Highest level	Master is the last level. A Master villager adds no more trades.
