You should play this because you have a good passive laning phase to scale. Harder matchups become fairly easier and with this build you can achieve the same AD as the normal build but you will be more tanky than ever before. I made this guide for fiora players who already know how to play the champion, so i will not go over the basics.

Grasp offers something that Conqueror does not offer and that is sustain in lane. Grasp is a free poking tool while it also scaling with your build over time. let's first look at the keystone:

PASSIVE: Entering combat generates 1 stack every second for the next 3 seconds. Additional stacks may be generated by re-entering combat after 2 seconds. After reaching 4 stacks, your next basic attack on-hit within 6 seconds against an enemy champion consumes all stacks to deal (Melee 4% / Ranged 2.4%) of your maximum health as bonus magic damage, heal for (Melee 2% / Ranged 1.2%) of your maximum health, and permanently grant (Melee 5 / Ranged 3) bonus health. The empowered attack duration refreshes whenever going in combat.

This means that it heals you, increses your maximum hp and does extra damage equal to 4% of your maximum hp. This gives you, like i said before, a ton of sustain, but also permanent scaling.

Demolish helps you with your splitpushing, there is not much to say other than it scales with your maximun hp as increased damage to the tower. It is also the best rune of the 3 options.

Bone plating is my personal favorite out of the 3, but the other 2 can also be used. Bone plating offers resistance to burst damage.

Overgrowth, revitalize or Unflinching is 3 good runes on fiora for this build:

Overgrowth helps you scale with even more hp for the build and demolish.
Revitalize give 5% heal and shield power which empowers her healing from her vitals, AOE ult healing, Grasp and Divine Sunderer. While you are under 50% hp the runes stats increases to 10% healing and shield power.
Unfliching is good for cc, so you can move.

Yes, i have. I play on the best european server ever you know it, EUNE. I want to talk about the trademark on this build, because i made this build from a lot of testing so i like kinda want to get recognized with ownership of this build.
Lastly im making a montage for the people who dare to play my build, so i was love if you sent some clips to me over discord (Lonely Boy#9975).

I love making fun build, but i really wanted to try making something meta changing for Fiora and i really had fun writing all this to expand my build.
