The final boss of Star Ocean: The Second Story made me feel smart--it's a JRPG with real-time (though you can pause) and more actiony combat; you actually run up to the enemy to fight it within the constrained, instanced battlefield of traditional JPRGs. 2D sprites on a 3D battlefield kinda thing. You can fight with up to a party of 4 at a time. You control one character directly, while the AI operates the other 3. You can give the AI guidelines to operate by, and you can pause and take direct control of another character at any time.
So, almost right off the bat, the final boss opens with an unavoidable blast wave that will likely outright kill your entire party (unless you grind for a ludicrous amount of time). I had read little snippets about the final boss on GameFAQ guides, because I was stuck on a earlier boss, and I expected I'd never beat it (I had already ground for a month<--that is a guess; just couldn't bring him down). So, my wanting to at least read about the final boss lead to my knowledge of his opening blast wave attack. Every guide I had read advised that you max out one characters' parry and avoidance stats, so he could then hopefully survive the initial blast and revive the other party members to continue the fight (Star Ocean had a TON of secondary stats--that were convoluted to my young mind). These secondary stats differed among party members, so only this one specific character could survive the blast, if you maxed out his avoidance-type stats, allegedly.
As I gave up on the earlier boss I was stuck on, I started to wonder if Head Splitter could circumvent the blast wave entirely. But, I dropped the game, not to return to it for years. One day around 7 years later, I thought of Star Ocean: TSS, and how I'd never defeated it. So, I decided to give it a whirl. I settle on some ground rules: I was definitely NOT going to grind anymore. No grinding, even if my characters' avoidance stats weren't high enough to survive the blast wave. If I couldn't beat the bosses and the final boss with my party as it was, I would just accept defeat.
Well, on my second or third try I took down the boss I had been stuck on years ago. Then I proceeded to defeat the next few bosses after that (the final part of this game is like... 10 bosses in a row), which were way easier than the one I had been stuck on. Finally, I reached the end boss of the whole game. I remembered that strategy I'd formulated long ago but never got a chance to use. I bet Head Splitter would totally clear me of that blast wave!
Head Splitter was a special move: one of two that could be equipped at a time by the fighter-paradigm characters. Basically they were special abilities like you'd have in a Diablo game. Head Splitter was an ability you earned early on in the game (and this is a LONG game), so I bet most people would have forgotten it existed by the game's end. Apart from being awesome, it wasn't much good even when brand new. But, the ability did cause your character to leap about 200 hundred feet in the air and come down on top of the target enemy's head. That was what I needed.
The final boss fight started and he immediately began to cast the blast wave spell. I used Head Splitter on the boss and leaped over the wave! YES! My 7-years-in-the-making strategy had worked! My other 3 party members were struck and KO'd. I revived one and then immediately began spamming my other special move, Mirror Slice (which is amazing!). When my item use cooldown refreshed I revived another one, while my first revived teammate employed magic to res the final piece of the team. It still took about 3-5 attempts, because the boss uses that move (or another one just as devastating) during the course of the fight too! To win I had to spam Mirror Slice like my life depended on it to keep the boss relatively stun-locked; he still had instant cast spells, but it prevented him from using the channeled and more disastrous ones; if I was knocked away for any amount of time we were screwed.
The final boss crumpled and I was triumphant! I think I was still underleveled too, seeing as how almost every spell he used killed my squad outright. Mirror Slice stun lock saved me, cause I definitely wasn't gonna grind anymore. That was probably my first 100+ hour RPG.
In short, I was smarter than the 3 or 4 guides I had read on a game in regards to the final boss fight. Go me! Also, being way better at games I sucked at years ago makes me feel clever.
