Real Talk Tip to NA F/GOers For The Long Run: Make sure you have this:

• A strong team of Casters, ideally including Single Target NPs.
• A strong team of Lancers, ideally including Single Target NPs.
• Servants that have Evasion/Invulnerability, Taunts, or both. David, specifically, can provide a full party one hit Evasion, so I recommend training him as well.

Casters counter Assassins and Lancers counter Archers. Why is this important? Enemy Assassins and Archers have a 3-charge gauge, the shortest in the game. They will NP every three turns. This is huge later on, when you fight bosses with 500k+ HP and in some cases with 1 million+ HP. Imagine trying to deplete 1 million HP with an NP coming at you every three turns. You WILL want maximum survivability, because no amount of DPS will help you avoid enemy NPs there.

You’ll want to be able to freely redirect and nullify enemy NPs as much as you possibly can. When you get sufficiently deep in the game, nullifying risk becomes impossible in many battles, and instead you minimize damage. You are going to EVENTUALLY take NPs, if a battle stretches out, so when that becomes the case, you want to have Class advantage at least. It can help you survive NPs and accelerate the damage process so you can actually win a fight at all.
