+--- Day 22: Wizard Simulator 20XX ---
+
+   Little Henry Case decides that defeating bosses with swords and stuff is boring. Now he's
+   playing the game with a wizard. Of course, he gets stuck on another boss and needs your help
+   again.
+
+   In this version, combat still proceeds with the player and the boss taking alternating turns.
+   The player still goes first. Now, however, you don't get any equipment; instead, you must
+   choose one of your spells to cast. The first character at or below 0 hit points loses.
+
+   Since you're a wizard, you don't get to wear armor, and you can't attack normally. However,
+   since you do magic damage, your opponent's armor is ignored, and so the boss effectively has
+   zero armor as well. As before, if armor (from a spell, in this case) would reduce damage below
+   1, it becomes 1 instead - that is, the boss' attacks always deal at least 1 damage.
+
+   On each of your turns, you must select one of your spells to cast. If you cannot afford to
+   cast any spell, you lose. Spells cost mana; you start with 500 mana, but have no maximum
+   limit. You must have enough mana to cast a spell, and its cost is immediately deducted when
+   you cast it. Your spells are Magic Missile, Drain, Shield, Poison, and Recharge.
+
+     • Magic Missile costs 53 mana. It instantly does 4 damage.
+     • Drain costs 73 mana. It instantly does 2 damage and heals you for 2 hit points.
+     • Shield costs 113 mana. It starts an effect that lasts for 6 turns. While it is active,
+       your armor is increased by 7.
+     • Poison costs 173 mana. It starts an effect that lasts for 6 turns. At the start of each
+       turn while it is active, it deals the boss 3 damage.
+     • Recharge costs 229 mana. It starts an effect that lasts for 5 turns. At the start of each
+       turn while it is active, it gives you 101 new mana.
+
+   Effects all work the same way. Effects apply at the start of both the player's turns and the
+   boss' turns. Effects are created with a timer (the number of turns they last); at the start of
+   each turn, after they apply any effect they have, their timer is decreased by one. If this
+   decreases the timer to zero, the effect ends. You cannot cast a spell that would start an
+   effect which is already active. However, effects can be started on the same turn they end.
+
+   For example, suppose the player has 10 hit points and 250 mana, and that the boss has 13 hit
+   points and 8 damage:
+
+ -- Player turn --
+ - Player has 10 hit points, 0 armor, 250 mana
+ - Boss has 13 hit points
+ Player casts Poison.
+
+ -- Boss turn --
+ - Player has 10 hit points, 0 armor, 77 mana
+ - Boss has 13 hit points
+ Poison deals 3 damage; its timer is now 5.
+ Boss attacks for 8 damage.
+
+ -- Player turn --
+ - Player has 2 hit points, 0 armor, 77 mana
+ - Boss has 10 hit points
+ Poison deals 3 damage; its timer is now 4.
+ Player casts Magic Missile, dealing 4 damage.
+
+ -- Boss turn --
+ - Player has 2 hit points, 0 armor, 24 mana
+ - Boss has 3 hit points
+ Poison deals 3 damage. This kills the boss, and the player wins.
+
+   Now, suppose the same initial conditions, except that the boss has 14 hit points instead:
+
+ -- Player turn --
+ - Player has 10 hit points, 0 armor, 250 mana
+ - Boss has 14 hit points
+ Player casts Recharge.
+
+ -- Boss turn --
+ - Player has 10 hit points, 0 armor, 21 mana
+ - Boss has 14 hit points
+ Recharge provides 101 mana; its timer is now 4.
+ Boss attacks for 8 damage!
+
+ -- Player turn --
+ - Player has 2 hit points, 0 armor, 122 mana
+ - Boss has 14 hit points
+ Recharge provides 101 mana; its timer is now 3.
+ Player casts Shield, increasing armor by 7.
+
+ -- Boss turn --
+ - Player has 2 hit points, 7 armor, 110 mana
+ - Boss has 14 hit points
+ Shield's timer is now 5.
+ Recharge provides 101 mana; its timer is now 2.
+ Boss attacks for 8 - 7 = 1 damage!
+
+ -- Player turn --
+ - Player has 1 hit point, 7 armor, 211 mana
+ - Boss has 14 hit points
+ Shield's timer is now 4.
+ Recharge provides 101 mana; its timer is now 1.
+ Player casts Drain, dealing 2 damage, and healing 2 hit points.
+
+ -- Boss turn --
+ - Player has 3 hit points, 7 armor, 239 mana
+ - Boss has 12 hit points
+ Shield's timer is now 3.
+ Recharge provides 101 mana; its timer is now 0.
+ Recharge wears off.
+ Boss attacks for 8 - 7 = 1 damage!
+
+ -- Player turn --
+ - Player has 2 hit points, 7 armor, 340 mana
+ - Boss has 12 hit points
+ Shield's timer is now 2.
+ Player casts Poison.
+
+ -- Boss turn --
+ - Player has 2 hit points, 7 armor, 167 mana
+ - Boss has 12 hit points
+ Shield's timer is now 1.
+ Poison deals 3 damage; its timer is now 5.
+ Boss attacks for 8 - 7 = 1 damage!
+
+ -- Player turn --
+ - Player has 1 hit point, 7 armor, 167 mana
+ - Boss has 9 hit points
+ Shield's timer is now 0.
+ Shield wears off, decreasing armor by 7.
+ Poison deals 3 damage; its timer is now 4.
+ Player casts Magic Missile, dealing 4 damage.
+
+ -- Boss turn --
+ - Player has 1 hit point, 0 armor, 114 mana
+ - Boss has 2 hit points
+ Poison deals 3 damage. This kills the boss, and the player wins.
+
+   You start with 50 hit points and 500 mana points. The boss's actual stats are in your puzzle
+   input. What is the least amount of mana you can spend and still win the fight? (Do not include
+   mana recharge effects as "spending" negative mana.)
+
+   To begin, get your puzzle input.
