Xeno Pets have been part of Survivor.io for a while now, but many players are still confused about which pets are worth deploying and how to build them efficiently. This advanced guide breaks down everything you need to know about pet selection, assist skills, and smart investment so you can maximise their potential.
Why Raw Damage Doesn’t Matter
If you look at the total damage charts in modes like Ender’s Echo, you’ll notice that Xeno Pets barely contribute. Their direct DPS is insignificant compared to your main build.
What really matters: Awakening Skills at 4 Stars.
10-star awakenings are too far out to be reliable yet, so focus on pets that provide strong buffs/debuffs rather than raw output.
Key Pets and When to Deploy Them
Choosing the right pet is about understanding your own stats and the buffs/debuffs available in each mode.
- Buffo
- 1-star: Inflicts Poison + Weaken.
- 4-star: +70% damage to poisoned targets.
- Great if your build lacks poison/weaken sources.
- Clocker
- Boosts critical hit potential.
- Best for players with low Crit stats.
- Situationally strong in Lunar Mine Expedition because of extra buffs.
- Cappy
- Increases skill damage.
- Only valuable if your Skill Damage stat is weak.
- PA
- Boosts damage to poison targets.
- Best choice for players with low poison multipliers.
- Not always reliable in modes where poison damage gets nullified.
General Rule:
- Clocker = good for low Crit builds.
- Cappy = good for low Skill Damage builds.
- PA = good for low Poison Damage builds.
- Buffo = must-have if you can’t apply poison/weaken elsewhere.
Assist Pets and Skills
It’s not just about the deployed pet — Assist Skills (AS) also play a huge role.
- Deployed pets’ skills remain active even when they’re assist pets.
- Best Assist Skills:
- Resonance Damage → increases your overall damage.
- Resonance Rate → increases the chance of triggering bonus damage.
These two should always be your priority when building assist pets.
Managing Xeno Boxes and Rerolls
When you open Xeno Boxes, you can exclude up to two unwanted Assist Skills.
- On paper, this increases your chances.
- But it also costs more crystals, making it inefficient in the long run.
- Reality check: it’s still luck-based, so don’t sink too many resources chasing perfect rolls.
Leveling Strategy
Since pet cookies are scarce and not refunded fully on dismiss:
- Level pets with Xeno Rate or Xeno Damage as their first skill.
- Take them to level 13 first.
- At level 30, check the second skill:
- If it’s strong (Resonance/Rate/Damage), keep leveling to 60.
- If it’s weak (like Health), dismiss the pet and recycle resources.
- Repeat this same logic at level 60 for the third skill.
This system minimizes wasted cookies and ensures you only invest in pets with long-term value.
Final Tips
- Your best deployed pet depends heavily on your current stat weaknesses.
- Always balance between Crit, Skill Damage, and Poison multipliers when choosing.
- Don’t chase raw pet DPS — focus on buff synergy.
- Be patient with RNG — luck determines which pets become worth investing in.
Xeno Pets aren’t about flashy damage numbers but about amplifying your own build through buffs and assist synergies. With smart leveling and careful stat checks, you can turn them into a powerful backbone for late-game content like Ender’s Echo and Lunar Expeditions.
