Multi-Attack Protection (MAP)

Multi-Attack Protection (MAP) (formerly known as Gangbang Protection GBP) is a game mechanism introduced which aims to increase the protection conferred to Provinces which have been recently hit.
Current MAP Status/Level can bee seen under Affairs of the State.
Failed Attacks also increase the MAP of the defender, based on relative Offense sent/Defense, linearly scaling from 0 to half the amount of MAP generated on a successful Traditional March.

Effects of MAP

• The more MAP on your Province, the less an Attack will gain from you - all other variables being equal.
• Increases Military Efficiency.
• Reduced Military Casualties equal to Gains reduction
• MAP rounds off to the nearest percentage (eg. it can be 20% or 21% but not 20.5%)
• MAP is almost negligible in War.

MAP Status (Level)	MAP rating	Gains Out of War	Gains in War	Increase in ME	MAP Decay
Not Hit	0%	100%	100%	N/A	0
Couple	1-20%	80-99%	80-99%	+0.13-2.67%	1
Moderately Hit	21-40%	60-79%	80%	+2.80-5.33%	1
Heavily Hit	41-60%	40-59%	80%	+5.47-8.00%	2
Extremely Heavily Hit	61-90%	10-39%	80%	+8.13-12.00%	3 or 4 if above 79%

Attacking MAP Change

Land Attacks

 A land attack (Traditional March, Raze or Conquest) increases the MAP rating by 2.75 * Percent of Targets land taken. 

For example if a target is attacked for 120 of its 1000 acres (12%) its MAP/GBP rating will increase by(12% * 2.75 = 33%) 33 points, taking it from 0% to 33% if previously un hit - enough to put it into the 'moderately hit' section.

Non-Land Attacks

 Non-Land Attacks (Plunder  or Massacre) increase the MAP/GBP rating by 0.06 * Current Gains OOW
 Learn increases the MAP/GBP rating by 0.12 * Current Gains OOW

For example if a target with a MAP rating of 20% (and thus Gains OOW of 80%) which is hit for a Plunder, it will boost its GBP by (0.06 * 80% = 4.8% rounded off) 5% to 25%.

MAP Decay

• MAP rating naturally decreases every Tick by an amount dependent on the current MAP rating as shown in the above table. For example if the MAP rating is currently 59% (heavily hit), on the next hour change it will decrease by 2% to 57%.

• MAP also decays whenever the province with MAP makes an attack.

Military Effectiveness

MAP gives a bonus to Military Effectiveness equal to the MAP rating / 7.5

For example if the MAP rating of a province is 59% (heavily hit) their ME is boosted by (59 / 7.5 = 7.9%) 7.9% - ie. 1.079 times it's current rating.
