What was her level though? Chances are it's so high that you'd be bored outta your skull before being willing to do that (for the whole game). Not to mention that particular boss is actually pretty easy in that regard. Eiki for example would be a much better example of one difficult to solo (or 4man).
I don't mean to be a buzzkill, if you want to do this be my guest. But honestly. I hear 90% of the people who try this game have one gripe about it. and that is that it requires grinding. I find I'm one of very few people who say "actually it doesn't", to hear people suddenly decide it wont require a stupid ridiculous amount of grinding to accommodate for a self-inflicted shot in the foot is curious. Not to mention of of the cool aspects of this game is party dynamics, balance and design. Most RPGS limit you to a small party with no choice of who is in it. This one is no such game, and tha'ts quite frankly one of the features that make it awsome. Why you'd want to toss that is beyond me, but it is a game, and if you think it's fun go ahead. I remain skeptical that any of you (or anybody else) would enjoy it though >=P.
Seriously, I'm not sure where the "grinding is necessary" mentality comes from. The only bosses I ended up grinding for were
because I needed to be able to get through the first five fights with a decent amount of SP and TP, and currently
because I'm apparently so underleveled that I can't survive until my first turn :ohdear:
Really though, any fight where it seems like you'd be underleveled can be solved with careful use of status ailments, buffs/debuffs, and other strategies. For example, I beat Flan at level 65 with only 3 characters really doing anything by letting my entire active party sans my tank die off at the start, then swapping in Sanae to buff
, have her drop a nuke or two, then switch them both into the empty slots so my tank could take 0 damage from a Laveatein, rinse and repeat until win.
EDIT: Speaking of the 16F fight, I'm getting my ass kicked. I can't keep more than one attacker alive until the last form. Current lineup (which I've kind of been fooling around with):
Reimu
Youmu
Current strategy: Have the tanks remove her buffs, either via actually removing them or through debuffs, then try to slaughter her with nature-element attacks. I've been having
buff attack while Reimu buffs defense, but
been rather useless for the most part, mostly due to the fact that by the time I've got the boss debuffed and the rest of the team buffed and healed to a safe level I get Djinn Storm'd, so I might switch her out for Sakuya so I can just speed buff everyone on the first turn and be done with it.
