New mob: Necromancer

• Purpose: the idea is to create a versatile mob that adapts to the player attacking him, making it impossible to kill by a single player. 
• Location: gold chest at T3 and IB, guarded by three berserked DOMP Liches as well.
• Sprite: black Liche.
• HP/DR/MR/HR/PA/MA: same as Fire Wyvern.
• The Necromancer won't have any physical attacks.
• Interaction: the Necromancer adapts to the player damaging him after five successful hits. For example:
  • If the player ticks it with poison five times, it gains 90% poison resistance.
  • If the player hits him physically five times, it becomes "invisible" (gray) until it recovers HP. Any magic spell (including AoE magic) will remove the invisibility.
  • If the player hits him magically five times (can be a single spell, AoE effects also count), it will cast PFM or AMP on itself or cast Cancellation on the attacker. If he becomes invisible the PFM or AMP will wear off.
  • If he gets attacked with fire magic five times, it will become Fire element. Same with all the other elements.
• These are the spells he can cast:
  • If he is Neutral he will cast Divine Touch. If he's any element he will cast the circle 10 of the element.
  • Cancel
  • PFM/AMP
• Drops: same as Fire Wyvern

I know this might be a nightmare to code but it seems like the next step, to have non-linear adaptative mobs that require non-linear approaches to hunting.
