4th mission - A Battle Lost and Won M&M: Heroes VI Guide
Last update: 11 May 2016
Human's country capitol is besieged by demons - only Anton is able to fight with overwhelming forces of enemy.
Main quest: Demons at the gates
Objective: conquer the closest city
Reward: 25000 XP, +2 to might defence, +2 to magic defence
Mission is very easy - we have to reach first city occupied by demons (M12,2) and fight it back. Enemy's army is numerous, but without any hero. As we have Anton, the result of a encounter is known: we just need to heal our units and cause big damages.
 It's our goal
|  After taking this city, we should continue our exploration
|
Main quest: Breaking a siege
Goals: conquering and converting four Inferno cities, taking over forts around Hawk's Nest
Reward: 40000 XP, guard breastplate (+4 to might defence, all units in hero's army resist all damages during first three turns in every battle)
Our goal is conquering four cities (M12,3), which surround human capitol. This quest isn't difficult but time consuming - we have to expect attacks from every directions and getting another castles one by one. Patience should be our main advisor.
 Demons settled in our kingdom
|  But we'll smash them!
|
First of enemy's city is on the northern east - near to the fortress (M12,2), we took in Demons at gates quest. Conquering this castle won't be easy, so we should improve our army earlier - especially radiant glories will be important for us. Constantly crossbowman fire, charge of sentinels and crusaders plus healing spells of sisters will give us a victory.
 Don't forget about convertion
|  We'll disadvantage enemy quickly
|
Other Inferno cities (M12,3) we can seize in random sequence - it doesn't matter. But we have to remember about defence - hiring few heroes sounds like good idea. It's worth also to do quests The Prophecy and The Support which make our expansion easier.
During sieges we'll focus on eliminating enemy's shooters (especially breeder mothers, who can replicate) and destroying gates. To both tasks crossbowmen and radiant glories are the best choice, but we can decide on something more brutal, like rush of seraphs and gryffins inside a walls. Of course - don't forget about healing troops.
When all four cities will be ours a gate (M12,4) to the Hawk's Nest will open - to reach a capitol, we'll have to seize the last two enemy's forts (M12,5). Those, luckily, won't we a challenge - we should massacre defenders. When it's done, we obtain the last one mission in Haven's campaign - Griffins Valour.
Main quest: Prophecies
Goals: go to the undergrounds, conquer those cities and release an empresses
Reward: 55000 XP, angelic alliance (+3 to might attack)
This mission activates when we reach a downstairs to underground (M12,X) - angel Jezebeth asks us to defeat demons in their own lair. To do so, we have to go under the surface of the land.
 Four sieges - piece of cake!
|  Convert, convert, convert
|
As we'll see quickly, a way to empresses city (M13,1) get blocked by chaos magic - to break the spell, we'll have to conquer two hellish cities (M13,2) and convert them. It's easiest to move east (there is a strong troop of pit lords on the west), where we can take enemy's fort (M13,3), and then a castle. After that we should replenish our forces, and move further on the west (clockwise). In a short time we'll see another fort (M13,4) and the second city. After collecting them, a way to empresses will be open.
When the spell broke, we can start a rescue action. Nearby a castle we have to seize, is a trap - angel Jezebeth betray us and attacks with army of demons. When we defeat her we obtain a reward: Asha's Tear and all undergrounds passages (M13,X) unlock, so we'll be able to move freely.
What's important, thanks to our work, Sveltana with necromancers will help us - she'll conquer one hellish city (M12,6), facilitates our quest.
Main quest: Griffins Valour
Attention! This quest get activated after finishing Breaking a siege!
Goals: defeating Ahribban
Reward: 30000 XP
After conquering four Inferno cities (M12,3) and two forts (M12,5), has come a time for ultimate battle with demons. Huge monster, demon Ahribban, siege human's kingdom capitol (M12,7) - we should send our best hero to fight him with possible largest army we can. At this stage of game, we'll have plenty of cities and Inferno doesn't count anymore, so it's worth to wait a while and create a enormous army (Ahribban has always the same power). In quest Breaking a siege we obtain very useful artifact, which gives us big advantage.
Encounter with monster is very schematic - enemy will summon little troop of demons in every turns (they goal is to get into the capitol), and attack us himself. Very important thing is fact, that we control not only our army, but also units defending in a capitol - so we can attack him from two sides. It's matter, because death of those defenders equals our defeat - so we should care about their health.
The battle is a scheme: most of our forces have to attack Ahribban, and one-two troops eliminate demons he summons (defending a capitol, indeed). Enemy has huge HP and powerful attack, also unlimited mobility. To defeat him, we have to just attack him frequently causing huge damages. Especially sisters are good at it - they cause additional damages to darkness units. One more thing is important - in every turn the same unit should attack him first - Ahribban in counterattacks divides damages between all units he hurt.
When demon dies, the campaign is over.
Secondary quest: The Support
Goals: meet with emisaries from Deer Duchy
Reward: +50 marksmen, +25 sun crusader, guard shoes (+1 to movement on the land, +1 to might defence)
This mission is getting done by doing Breaking a siege - whatsoever we have to move nearby Deer's castle (M12,8), so we can visit them.
The only one goal of a mission is reaching our allies castle - when we do, they join us and we get this city. It's serious support for our kingdom, so we should take it.
