Olden Era Hive Faction Guide: Swarm, Retaliation, and the Zoran Opener

Hive is the faction almost nobody is writing about, which is a shame, because once it clicks it’s one of the most aggressive, snowbally armies in Heroes of Might & Magic: Olden Era. It lives on lava terrain, it fights with insects, and it wants the battle over fast. If you like grabbing the opponent by the throat on turn one and never letting go, keep reading.

I’ll be straight about the meta: in the current Early Access build, the GamesRadar faction rating puts Hive at A tier, behind the S-tier factions but very much a real contender. Different tier lists rank it differently because EA is still being tuned, so take any ranking as a snapshot, not gospel. What matters is the playstyle, and the playstyle is good.

What Hive Actually Is

Hive is lava-native, which means no movement penalty on lava terrain plus a first-strike edge there. The army theme is a swarm: lots of bodies, cheap aggression, and sustain that keeps the bugs coming. It does not want a slow attrition war. It wants to overwhelm before the enemy can stabilize.

The two mechanics that define the faction are Summon Swarm (the faction skill) and Corpse Eater sustain. Learn those two and you understand Hive.

Summon Swarm

The faction skill lets your hero plant an egg that hatches into Fire Larvae on the following turn. It’s free extra bodies mid-battle. The catch worth knowing: the summoned Larvae’s HP scales off your total Hive Spawn HP, so the more swarm you bring, the more the summon is worth. Check the in-game card for the exact scaling in your build, but the direction is clear: Summon Swarm rewards committing to the bug theme rather than splashing it.

Corpse Eater and Hivemind

This is the engine that makes Hive’s aggression sustainable. Corpse Eater units eat corpses on the battlefield to heal, which means every stack that dies, yours or theirs, becomes fuel. In a long fight that’s a snowball: the more things die, the healthier your bugs get. Hivemind-style sustain keeps the swarm topped up so you can keep trading aggressively instead of bleeding out. Confirm the exact numbers on the unit cards, since EA keeps adjusting healing values.

The Roster, T1 to T7

Here’s the tier ladder so you know what you’re building toward:

1. Parasite (T1)
2. Locust (T2)
3. Hornet (T3)
4. Scorpion (T4)
5. Reaver (T5)
6. Waurms (T6)
7. Hive Queen (T7)

The low tiers are your disposable swarm, the bodies you throw forward to bait, block, and trade. The high end, Waurms and the Hive Queen, are where your real punch lives. For exact stats, speed, and abilities, pull up the in-game unit cards, because those move between patches.

The Standout Hero: Zoran the Self-Founded

If you want to feel how strong Hive can be, start a run with Zoran the Self-Founded. He opens with 2 Waurms in his army, and combined with Corpse Eater sustain that early-game pairing is borderline unkillable in the opening fights. You walk into neutral stacks that would chew up a normal starting army and come out healed up off the corpses. It’s a fantastic snowball start: clear aggressively, eat the dead, roll into the next fight stronger. If you’re new to Hive, Zoran is the most forgiving way in.

The Core Trick: Baiting Retaliation With Split Stacks

This is where Hive’s swarm identity meets Olden Era’s combat rules, and it’s the single most important micro skill for the faction.

The rule it exploits: each enemy stack only retaliates once per round. When a melee attack lands, the defender hits back, but after that one retaliation they’re “spent” for the round and can’t punish the next attacker.

So you spend the swarm’s cheapness on it. You split a single body off a stack (CTRL + click to split one creature; CTRL + SHIFT + click to fill a split stack) and throw that one expendable bug at the dangerous enemy first. It absorbs the retaliation. Then your real stack, the Waurms or whatever’s carrying, comes in immediately after and hits with no counterattack waiting for it. You traded one Parasite or Locust for a free, retaliation-less swing from your heavy hitter.

Hive is built for this. The swarm is cheap, you have bodies to spare, and Corpse Eater means the bait you sacrifice often gets recouped as healing fuel anyway. Once you internalize “split a bug, eat the retaliation, then hit clean,” your fights get noticeably one-sided.

You can use the same split trick to throw a one-creature body in front of enemy ranged units, soaking shots that would otherwise hit your important stacks. Cheap bodies are a resource. Spend them.

Don’t Wreck Your Own Morale

One mistake I see new players make across every faction, and it punishes aggressive armies like Hive hardest: don’t mix factions in your army. An all-Hive force gets a +1 Morale bonus. Every additional faction you fold in costs you -1 Morale. Morale matters because good morale gives stacks a chance at an extra action and bad morale can make them freeze. For a faction that lives on tempo and getting its hits in first, an extra action at the right moment can decide the fight. So as tempting as it is to grab some strong neutral or off-faction unit you found, keeping the army pure Hive is usually worth more than the raw stats.

(Side note: Undead and Construct units always sit at neutral morale, but that’s not your concern with a bug army.)

How to Pilot a Hive Run

Put it together and the gameplan reads like this:

• Open aggressive. Hive wants early fights. Clear neutrals fast, especially with a Zoran-style sustain start.
• Build the swarm wide. More bodies means better Summon Swarm scaling and more retaliation bait to spend.
• Use Summon Swarm every fight. Free Fire Larvae are free tempo. Plant the egg early so it hatches in time to matter.
• Bait, then strike. Split a cheap bug into the retaliation, follow with your carry.
• Keep it pure Hive for the morale edge.
• Let the corpses feed you. Don’t avoid the messy fights, Corpse Eater turns carnage into healing.

Hive isn’t the safest faction in the Early Access build, but it might be the most fun if you like pressing the advantage. Lean into the aggression, abuse the one-retaliation rule, and let the swarm do what swarms do.
