- Necropolis armies have many units with abilities to weaken their opponents. This may give them an advantage over an equal or even a stronger opponent.
- All Necropolis' creatures are undead, which means that they are unaffected by morale. They are also immune to all mind spells as well as Curse, Bless, Resurrection and Death Ripple.
- Necropolis is one of the most powerful towns. It has very strong 4th, 5th and 6th level creatures. Vampire Lords and Dread Knights are among the strongest in their respective levels, and while having Power Liches in an army consisting of living creatures may have problematic because of the death cloud attack, in the army of undead it is an advantage. Skeletons are around average rank of 1st level creatures, but due to Necromancy secondary skill, their numbers can be signifcantly greater than other 1st level creatures. The downside is, that Walking Deads, Wights, and Bone Dragons are all among the weakest creatures of their respective levels. In fact, Bone Dragon is perhaps the weakest 7th level creature.
- Necropolis has excellent magic capabilities. It can build level 5th Mage Guild and has few special spells like Animate Dead and Death Ripple to support the armies. Also, undead hordes are immune to mind spells, which greatest advantage is that they cannot be blinded or "berserked". In addition, undead do not suffer from negative morale (nor do they benefit from positive). This makes the Spirit of Oppression a useful tool for Necropolis armies.
- Perhaps the most outstanding feature closely related to Necropolis is Necromancy secondary skill. It enables heroes with the skill to "harvest" Skeletons (or Skeleton Warriors) from enemy armies as well as allied creatures. It is possible for a hero with Necromancy skill to come out from a battle with more troops than he went to it.
- An advantageous tactics with Necropolis is "harvesting" skeletons with the Necromancy secondary skill. At expert level Necromancy allows 30% of the creatures killed in combat to be brought back from the dead as skeletons. The percentage points can be increased with two structures: Necromancy Amplifier(s) and Soul Prison. Amplifiers can typicallly be constructed in necropolis towns, while Soul Prison is the grail building of Necropolis. Each amplifier increases the percentage points by +10%.
- There are also artifacts that can increase the skill: Amulet of the Undertaker increases the percentage points by +5%, Vampire's Cowl by +10% and Dead Man's Boots by +15%. With these increase, Necromancy secondary skill may rise up to 70%. Additionally, two heroes specialize in Necromancy, Isra and Vidomina. Combining either of them with the amplifier and artifacts, it is possible to reach 100% skill level in necromancy, which means that possibly all the creatures killed in combat will be brought back as skeletons.
- Harvesting leads to a situation, where it is profitable for heroes with Necromancy (mainly Death Knights and Necromancers) to carry through combats with wandering creatures instead of letting them flee if they are substantially less creatures and want to quit the battlefield. So, special months (see growth) where some creature types population doubles is actually a boon for Necropolis skeleton harvesters. This is especially valid for low-level creatures that come in large numbers, like hobgoblins. Random units blocking pathways on the map thus become a motivational boost because those wandering creatures mean additional Skeletons.
- A variety of good heroes to choose from
- A variety of strategies available
- Units are unaffected by negative Morale thus unaffected also by Sorrow or Spirit of Oppression, mixing with other Town type units still has a penalty on units of other towns.
- Unaffected by Mind spells like Elementals, even Blind does not function on Undead units.
- Necromancy is a powerful secondary skill that only Necropolis town heroes can utilize effectively and that every Necropolis hero typically has. Given affordable Necromancy amplifier buildings (10% point building bonus to Necromancy, unique town secondary skill boost building feature for all own heroes on the map, safe the Navigation centric building Lighthouse the only secondary skill bonus enhancer building available in the game) in Necropolis towns and a range of artefacts that further enhance the skill percentage like Vampire's Cowl it is rather easy to recruit a small but steady number of Undead from most other creatures after fights. Every successfull fight will increase the number of level 1 units one has even to astronomical amounts of stack sizes for steady motivation boosts after each encounter. Undead generally are Animate Dead ressurectable during combat additionally and the Skeleton Transformer in a Necropolis town can change foreign units to Skeletons so mixing foreign units with Necropolis town units does not make them suffer morale penality when converting them to Skeletons first, one can recruit units off fights with the opponent and they are rather hard to kill and easily replenished given enough mana or Necromancy skill bonus points which are readily available via buildings or artefacts or even hero specials.
- Vampire Lords are by far the most cost-efficient level 4 unit (and arguably the most cost-efficient unit in the game), as they can beat armies of much greater size as long as they are not (like Undead,Constructs or Elementals) immune to the Vampire Lords' Life drain ability and as long as the Vampire Lords are used properly (with Blind on extra enemy stacks for example or Counterstrike on the Vampire Lords amidst low number/low hp enemy stacks, alternated with Animate Dead to help out if the Life Drain to damage inbound ratio is proving destructive to the Vampire Lord stack - perhaps also using Haste and the Flying feature of the Vampire Lords to switch opponent melee stacks to feasible ones or to seek a safe point to replenish via Animate Dead, Cure or First Aid should Life Drain prove to be effectively ineffective due to outrageously onerous enemy aggression without rhyme and reason).
- The level 3 spell Animate Dead (which the necromancer hero Thant has built in) can resurrect units in combat, and they stay resurrected after combat. So given a good balance of Thants undead and repairable units compared to the opponent, enough mana for the resurrects and having Shackles of War for unlimited turns (a smaller version would be using Blind on all remaining enemy units and killing one blinded stack each turn, keeping the enemy locked until the enemy hero is lost to the opponent and the artefacts if any are transferred) he would not lose any units in combat but also often get additional Necromancy created skeletons (which would hamper movement on the adventure map a little, as Skeletons are slow creatures (and even with Town Portal and Dimension Door there's an adventure map movement penalty to consider)).
- There are number of artifacts that are only useful to Necropolis (artifacts enhancing the created creature number of the unique secondary skill Necromancy like Cloak of the Undead King, but also Pendant of Death which counters the mini, undead-only version of Armageddon, damaging all undead on the battlefield, even those recruited in no Necropolis but on the adventure map).
- Both Necropolis hero types begin with a spell book
- Walking Dead and Zombies slow armies down
- Only one ranged attacker Lich/Power Lich which also has a Melee penalty, no Double attack and cannot attack Siege Walls.
- Unaffected by positive Morale. Mixing creatures of other town types without converting them to Skeletons via Skeleton Transformer first will get them negative Morale of course, on the other hand Spirit of Oppression is a very nice thing to have for any Necropolis hero with only Necropolis units in the party as it does not do any harm to Necropolis units. The Dread Knights' Death blow feature works largely (no Luck bonus for the second strike) like an attack only, no movement Morale bonus would, but at a higher probability of 20% (high Morale has 12.5% of activating a second action each creature) and it is a natural feature.
- Difficulties in the early game, where your slow level 1 and level 2 creatures are not the best to conquer mines and explore the map (and in the endgame a host of in-combat ressurectable skeletons might hamper adventure map transfers (to reflag buildings for instance) safe for Town Portal which is a nice (and often banned) spell to jump the adventure map))
- Bone and Ghost Dragons are near the bottom of the Level 7's in strength and usefulness
- WARNING! This town is often considered too strong and thus is banned in many multiplayer games/tournaments.
If you can upgrade your Estate early, you should do so. The Vampire Lords are one of the best 4th-level creatures in the game. Since they draw life from their enemy, and resurrect themselves, they can be used to single-handedly take out large numbers of low-level creatures. Combine with "counterstrike" to get even better effect.
"The month of the Hobgoblin" and the like are Necromancers' wet dream. Just take your strongest hero and stockpile Skeletons. Necromancy adds a little bit of motivation on clearing maps - who needs experience and levelups, when there's Skeletons aplenty?
The Necropolis has only a few units they can rely on, the others can wait with being bought and, in time, even be ignored. The reliable units are: Skeleton Warriors, Vampire Lords, Power Liches and Dread Knights.
You get Skeleton Warriors only if your ranks are full at the *end* of combat and if you have a stack of Skeleton Warriors and no stack of Skeletons. The downpart is that you get less than if you'd get normal Skeletons (2/3rds as many). Therefore, if it is logistically managable, it would be better to try and get a horde of normal Skeletons first, and then upgrade them at a Necropolis or Hill Fort for the last battle.
If there are any Level 1 dwellings nearby, recruit them and take them to the Necropolis. If you have a Skeleton Transformer, you're practically getting free skeletons, and even free Skeleton warriors if there is a Hill Fort close by too.
