Funny Bits in Star Ocean 2 (229)

Attacking an enemy that's higher up will make Claude (and most of the other characters) jump-attack automatically. In some cases your character may miss the target and land on top of it, as you can see in the screenshot above. Standing on this particular enemy gives you a huge advantage, because you can keep hitting it from there while it can't counter.

Activating all the spheres in the Field of Intelligence unlocks a teleporter to the final room, where the Jewel of Intelligence is hidden: this is a symbol of power, and acquiring it means obtaining some of the power of the Nedians. This means there are also additional protection measures for it, case in point that weird-looking mechanical arm, which seems to operate automatically and is equipped with some nasty weapons. Once in a while it will fire a huge ray of... something, which really hurts: since it can reach the other end of the battlefield, you might want to move your rear characters away from the centre (the mechanical arm can't move from that line, so don't stand in front of it when you're not attacking it). To make matters more complicated, there are three stationary spherical 'things' assisting the arm, one of which absorbs Star elemental damage (like the sparks the Eternal Sphere shoots).

This final guardian isn't all that though (it's the Field of Intelligence after all), but in any case the final room is very close to the entrance, so you can easily get out to recover and save your game before the battle.
