There are 3 (technically 4 cus hybrid) routes in FF: Melee, Ranged, and Magic. From every argument I've seen so far, melee is hardest and ranged is easiest and magic is in the middle. Melee is the hardest because you HAVE to go up and personal which means you're gonna need to soak damage and thats exceptionally hard no argument in early game because defense don't matter until mid-late game. Ranged is obviously easiest because you can stay as far as you want and you have a decent damage option from the arnold slime quest early game. But for magic, the CHEAPEST option is 875k, so for a long while you're either gonna be chasing fireflies, finding plants, hunting presents, or poking monsters with your stick. And fire soul does deal decent damage sure, but in mid-late game, it gets tough because you're gonna be very slow which is the downside to magic unless you use a fair amount of equipment slots into movement speed. And FL is an option but you're gonna be getting hit a lot more than ranged but less than melee, but at least with melee you can max out in defense because your DPS accounts for that. Magic is gonna leave you with moderate defense and even midgame threats like giants can kill you in 2-3 hits. And you're slow like I said before so thats gonna happen. Going magic leaves you SLOW, SQUISHY, and with only MODERATE defense.
