So after more than a 1 year break, I decided to finally complete my playthrough. Went well so far, I beat Omega and the Weapons, and Jenova as well. Now I am stuck at Bizarro. I did not have a Game Over per se, but before I will be caught in a X-hours-long battle loop for nothing, I want to ask inbefore:
So normally after killing the Magics (arms), you can hurt the core. I fought Bizarro in Gjoerulv's mod three times so far - and whenever I killed the arms, the core was still immune to damage. I tried both orders (first killing the left, and the next time first killing the right), but everytime I was only able to attack the stomach or the head (whenever it revived). I tried physical damage, and magical (even Pandora's Box) So - was the order changed? Or did I do something wrong? I have found a youtube video of Sega Chief fighting Bizarro on Gjoerulv's mod- on his battle, I saw that after he killed the arms, he was able to deal damage to the core. It was uploaded 2013, so idk, maybe Gjoerulv actually changed this one again.
Can someone please tell me what to do / if I missed something? I really do not want to continue a tedious battle for hours only to find out that I either missed something, or if I just did it for nothing if it's a bug. Thank you.
It depends if you get a 1, 2, or 3 party battle. If you get a 1-party fight then you can just kill the parts and expose the core, but if multiple parties are involved then you instead have to swap teams to destroy their side of the Core before Team A's core becomes exposed.
2-Party Fight
-) Kill a body part (head is fastest, but arms will stay dead when killed and need to die anyway). Swap teams when prompted.
-) Team 2 needs to kill all their body parts to make their side of the Core damageable; kill the Core here, and then swap back to Party A
-) Party A now needs to kill the arms (and possibly the head if it revives) to get damage down on the Core. Once the Core is down, you're free to damage the torso but beware; the less limbs Bizarro has, the more he'll start to spam-cast his physical attack which ignores defence, hits the party, is non-elemental, and has a high chance to crit due to Bizz's luck stat.
3-Party Fight
-) The most complex, you need to kill 3 Cores and one of your teams has only 2 people on it. This team will need to be reasonably equipped in order to deal with their side.
-) For Team B and C, you're only dealing with one arm but this arm has 2 parts to it so watch out for that. Also, if the head revives then it makes the core immune again; I can't remember exactly but I think the arm itself for these two teams may also revive so timing may be needed. Try to save your big burst for when that core-side is exposed; if you need to reset summon uses, swap teams and re-attempt.
-) When you've killed the Core sides for B and C, it's back to team A to do what you'd usually do; kill the arms, the core, then torso. The 3-party fight can last a long time if you get locked into attrition with parts reviving before you can get decent damage down on the core-side so be prepared.
If any of your teams are struggling then you can use the Hades summon to apply the dual-drain status (or Flare spell); this'll greatly speed up the battle. If you want to get the most straightforward battle of 1-party, then you'll need to let Jenova Synthesis get 13 turns before Countdown is initiated (unless the AI here was changed). You can also make Bizarro + Safer weaker in terms of HP if you avoid using KOTR in the Jenova Synthesis battle.
