When building Fiona in Last Z Survival Shooter, you have some important choices to make in order to get the biggest bang for your buck as you simply can’t upgrade all heroes at the same time but you need quite a bunch to build your squads.
By fine-tuning the way you upgrade Fiona’s skills and gear, you can save yourself quite some Skill Books and Universal Shards in the process and as not all skills have the same amount of impact but have the same amount of costs leveling up, fine-tuning them is worth it in the end.
Important! If you want to check how well Fiona does in the current meta of all heroes in Last Z Survival, please check out my current tier list of all heroes here.
Tier B+Here is a quick overview of the rankings of Fiona for the different modes of the game. Please refer to the full tier list linked below to see the ranking of all heroes in Last Z Survival Shooter and full evaluation and priority.
Fiona’s Optimal Skill Upgrade Order
Upgrading skills is possible after you get Fiona to 1-Star and then you will be able to upgrade each skill in 5-level increments. While the first skills are rather easy and cheap, it will start to eat quite a bit into your Skill Books and as you can’t produce them, you might end up with half-built heroes. So, here is the order you should work on the skills for Fiona so you only spend the Skill Books where they actually provide good value:
Skill 1
Skill 2

Fiona’s Optimal Gear Setup
Now we have to take a look at the gear setup, as it takes a lot of time and resources to craft higher rarity gear and not all gear is as impactful as the other one and you have to gear a couple of heroes in Last Z Survival Shooter. Also upgrading gear gets very expensive and you simply can’t just pump all your Enhance Materials randomly on gear and with the diminishing returns (higher level upgrades give the same stat increase but get more and more expensive), resource management is one of the most important things to do here!
Minimum Build
This is the build you really should have to use this hero decently considering when you get access to it and where your account is at this point
The levels for each gear item here is:
- D3-Pistol: Level 10
- D3-Helmet: Level 10
- D2-Vest: Level 20
- D2-Boots: Level 20
- Exclusive Weapon: purple heroes do not have Exclusive Weapons in Last Z
Sweetspot Build
We know the best build is the one that is maxed out but unless you spend a ton of money on the game this is not realistically. This build here uses the best value of all the gear and the required goals you should have with this hero in the meta to be viable while trying to limit your investment as much as possible
- D3-Pistol: Level 🔒
- D3-Helmet: Level 🔒
- D3-Armor: Level 🔒
- D3-Combat Boots: Level 🔒
- Exclusive Weapon: Level 🔒

Optimum Build
This is the optimum build looking at the diminishing returns of your invest where it makes sense to take this hero in terms of gear. Max is great, I know, but realistically everything beyond this is just very expensive and wasteful in terms of resources at this point
The levels for each gear item here is:
- D4-Revolver: Level 30
- D4-Helmet: Level 30
- D3-Armor: Level 20
- D3-Combat Boots: Level 20
- Exclusive Weapon: purple heroes do not have Exclusive Weapons in Last Z
Conclusion
I hope this guide helped you to build your Fiona without just pumping your manuals into the skills. I assure you this will make your progress in Last Z Survival a lot faster and get the biggest bang for your buck in terms of making the skills rock that really make a big impact espcially as costs get higher and higher.
