Haven't played BLM much, can you tell me which move can negate these attacks?

Manawall blocks 2 physical attacks fully, including stopping movement effects (like landslide). Divebombs are also physical. High Voltage is magical, but since it only applies the debuff if you take at least partial damage from it, you can use manaward to eat the damage and not get paralyzed. Your group shouldnt really be letting HVs get through anyways though.
