G Devastator drains the player's HP through its Death Scythe and Life Shaver attacks. Death Scythe can be easily rolled through, but rolling through Life Shaver may result in the second attack hitting. It is advised to keep a Cure materia on for these fights and always attack the foe from behind as it is slow enough to let Zack get behind it. When it gets low enough on HP, it may start using its special skill, Typhoon, which does upwards to 2,000-3,000 damage. It may also attempt to drain Zack's MP via Osmose.
