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 can be seen under Affairs of the State.
Effects of Attacking MAP
- The more MAP on your province, the less an attack will gain from you - all other variables being equal.
- Increase in 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.
Note
The table below describes the MAP modifier itself, not final attack gains after all other factors. Final gains still depend on the full gains formula, including relations, stance, relative networth, and other modifiers.
| MAP Status | 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% |
Age note: Age 103 reduced maximum War GBP/MAP protection from 30% to 20%, which corresponds to an 80% War gains modifier rather than 70%.
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 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
Plunder or Massacre increase the GBP rating by 0.06 * Current Gains OOW.
Learn increases the 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%.
Failed Attacks and MAP
- Failed attacks increase the defender's MAP based on relative offense sent versus defense.
- Age 102: failed attacks scaled from 0 up to half the MAP generated by a successful Traditional March.
- Age 106: this was adjusted to scale from 0 up to half the MAP generated by a successful Raze, reducing MAP generated from failed attacks.
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 Tick it will decrease by 2% to 57%.
MAP also decays whenever the province with MAP makes an attack by the same amount as if it had made the attack on itself - except that it decreases the MAP rating rather than increasing it.
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.
