By fine-tuning the way you upgrade Fiona’s skills and gear, you can save yourself quite some Skill Medals 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.

Fiona’s Optimal Gear Setup(s)
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 War Survival Game. Also upgrading gear gets very expensive and you simply can’t just pump all your Upgrade Ore randomly on gear.

Fiona’s Optimal Skill Upgrade Order
Upgrading skills is possible after you get Fiona to 2-Star and then you will be able to upgrade each skill in 5-level increments. White the first skills are rather easy and cheap, it will start to eat quite a bit into your Skill Medals 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 Medals where they actually provide good value:

Fiona’s Exclusive Weapon + Mythic Awakening
Her Exclusive Weapon is a game-breaker honestly in S5! The way her stacks snowball is just out of this world and melts enemy teams like crazy, even just at Level 1 which is a huge difference to other Exclusives of other heroes in previous seasons since they sometimes had their op-threshold at higher levels. Surem her higher Levels do awesome stuff like strip buffs from enemies and you want it for sure but even at Level 1, her Exclusive already hits like a truck.
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 War 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.
