Abzu is a large, beastly boss encountered in the sewers. It is weak to Fire magic. Focus on attacking its horns to quickly build Stagger. When it charges, dodge to the side. It can inflict Poison, so have Antidotes ready or equip a Cleansing Materia. In its second phase, it will summon Abzu Shoats; deal with them quickly to avoid being overwhelmed. Use Cloud's Fire spells and Tifa's Focused Strike.
