Rewards
Arachsiam isn’t just a creepy extra; killing her gives you awesome rewards you need for your progression. Defeating the Arachsiam Boss will get you exclusive loot and resources to power up your character and base in Once Human:
- Energy Link – A rare power core to fuel your base’s generators or high-tech devices (no more scavenging for bio-fuel – this gives you serious bio-energy output).
- Gear Mod x2 – Two nano modules (gear mods) to upgrade your armor or gadgets, making you more survivable against other aberrants.
- Weapon Mod Parts – Parts to upgrade your firearms, so you can craft that perfect spider-slaying assault rifle or mod your shotgun for extra punch.

Together these rewards give you more power. You’ll get better gear, upgraded weapons and resources to fortify your base. In short, killing Arachsiam is worth it – and with our boost, you get all this guaranteed without the hassle.
Options
Whether you’re having trouble beating Arachsiam on Normal or want to conquer her on Pro, we have flexible Once Human Arachsiam Boss Boost options to fit your needs. Choose the difficulty and playstyle that suits your goals and our boost team will take care of the rest:
| Difficulty | Service Mode | Details |
|---|---|---|
| Normal Mode (Story) | Self-Play or Piloted | We’ll defeat it on Normal for you, completing the Realm of Nightmares quest. Great if you just want the Arachsiam Boss cleared and loot collected. |
| Hard Mode (Challenging) | Self-Play or Piloted | Our experts take down Arachsiam on Hard, where she hits harder and spawns more spiders. Ideal for extra loot – and yes, we’ll handle the limited revives and constant damage mechanics like pros. |
| Pro Mode (Nightmare) | Self-Play or Piloted | Conquer Arachsiam on the toughest difficulty. This mode is brutal (only 1 revive, high toxin damage over time), but our team will carry you through it for maximum rewards and bragging rights. |
These options are for every player – from those who want to play the fight to those who just want it done – to get past Arachsiam easily. Just choose your difficulty, choose play mode and we’ll do the rest with 100% success.
Requirements
Before you jump in (or before we do that for you), make sure you meet the key requirements to face Arachsiam in Once Human. Don’t worry – these are mostly in-game requirements to ensure a smooth boost:
- Mirage Monolith Access – You must have unlocked the Mirage Monolith (via the Realm of Nightmares quest) to access arena. In practical terms, the dimensional rift to her lair should be open and accessible. (If you haven’t reached this point, let us know – we can help with prerequisite steps separately.)
- Level 30 Character – It’s recommended to have a level 30 character. This encounter is a level 30 boss and below-level characters will get one-shot by her attacks, especially on Hard/Pro.
- Decent Gear & Ammo – Come prepared with good gear. Ideally, have an upgraded assault rifle and plenty of ammo and healing items. If you’re self-playing, pack Adrenaline Shots (for revives) and Activators (long-acting healing) – on higher difficulties you only get one revive and take constant damage during certain phases!
- Stable Connection – If you’re playing with us, make sure you have a stable internet connection to avoid any “lag got me webbed!” moments. If we’re piloting your account, just sit back and relax.
Meet these requirements and the Arachsiam Boss boost will be a breeze (or as smooth as blasting a giant mutant spider can be). If you’re unsure about any requirement, our team is here to help – we’ve got your back from start to finish.
How to Boost Arachsiam Boss in Once Human
Boosting Arachsiam requires skill, strategy and maybe a sense of humor about getting webbed in the face. Thinking of taking on Arachsiam Boss yourself? Here are some battle-tested tips from experienced Once Human players (this is basically how our boosters do it – and why they make it look easy):
- Stock Up on Supplies – This fight is a marathon, not a sprint. Bring tons of ammo, healing items and buffs. Adrenaline Shots (for revives) and Long-Acting Activators (health regeneration) are lifesavers, especially in Hard mode where your revives are limited and the boss’s toxin aura hurts you. Running out of supplies mid-fight while it still has half her health is a bad time.
- Keep Your Distance – Arachsiam has brutal melee combos and point-blank web attacks. Fighting her up close is like volunteering to be spider food. Use assault rifles or sniper rifles to boost your damage from afar. Keeping distance gives you more time to dodge her pounce and her forward-charging swipe. Basically, treat her like the floor is lava – don’t stand right under her unless you enjoy getting stomped.
- Aim for Weak Spots – Those big green and purple sacs on her abdomen and her ugly mug (head) aren’t just for show – they’re her weak points. Focus fire on the head and abdomen whenever possible. In co-op, coordinate so someone is always hitting a weak spot. The faster you burn her health, the less time there is for things to go wrong.
- Dodge Web Attacks – Arachsiam will spit cobweb projectiles that stick to surfaces and the ground. If you get hit or step in these, you’ll be bound and unable to move for a few seconds – basically a death sentence if she follows up with a big hit. Keep an eye out for incoming webs (they’re white gobs she hurls at range) and dodge to the side. Pro tip: keep moving; a moving target is harder for her to snare.
- Destroy the Spider Eggs – Throughout the fight, Arachsiam will lay eggs via her Nurturing Larvae skill. These eggs spawn nasty little spider aberrants that explode or swarm you, and during her “Mist” phase the eggs even make her invincible until destroyed. Prioritize shooting the eggs as soon as they appear (they often sit at the ends of her web bridges or around the arena glowing red). Clearing eggs not only stops the spiderling onslaught but also removes her immunity shield so you can resume damage.
- Use Cover During Mist – When Arachsiam scurries up her central pillar and shrouds the arena in a poisonous fog, visibility drops and you’ll take constant chip damage on Hard/Pro. Immediately get behind something solid or create distance to avoid her unseen ranged attacks in the mist. Use this time to hunt down those glowing eggs through the fog (a DOT effect on her can help you track her as well). Once you pop all the eggs, the fog clears and she comes crashing down stunned – giving you a window to deal heavy damage.
Now you know what to do. Of course, knowing what to do is one thing – executing it under pressure (while an oversized spider is trying to eat your face) is another. That’s where ChaosBoost boost service comes in: we already have this fight down to a science, so you don’t have to stress.
