Weapon Encounters

Diamond Weapon is a scripted Weapon encounter, but it can still punish sloppy timing. Lightning is the listed weakness, and magic is especially important when its defenses make physical attacks unreliable. Steal the Rising Sun before ending the fight if you want the weapon. Heal before Diamond Flash and keep pressure steady; this battle is about surviving the countdown-style bursts rather than trying to out-trick the boss.

Emerald Weapon is the game's underwater endurance superboss. Bring Underwater Materia unless you are intentionally racing the timer, and watch Materia count because Aire Tam Storm scales brutally with equipped Materia. Big Guard, HP Plus, Final Attack/Phoenix, Mime, and high-end Limit or summon strategies all matter more than elemental weaknesses. Remove or manage the eyes when they appear, then return to the main body before Emerald Beam and Revenge Stamp grind the party down.

Ruby Weapon is a superboss built around party control. Entering with two characters down is the classic way to prevent Whirlsand from removing your active team, then revive once the tentacles are established if your strategy calls for it. Hades, Dazers, or other paralysis-style control can create the window for Knights of the Round and Mime loops. Keep Final Attack/Phoenix or a comparable safety net ready, because Shadow Flare, Ultima, and the tentacle counters can end a greedy attempt instantly.

Ultimate Weapon is fought across multiple encounters, so think of each battle as progress toward a shared HP pool. Long-range damage, strong magic, and Limits help when it is airborne or awkward to reach. Steal the Curse Ring if you want it, and prepare Enemy Skill Materia before the final fight if you want Shadow Flare from its last attack behavior. Do not burn all resources in early meetings; save the strongest push for the final stop.
