Jenova Dreamweaver is an illusion of Jenova, caused by its ability to project false images to its victims. It is a grotesque creature with a skeletal head and various tentacles, resembling Jenova's forms from the original Final Fantasy VII.
In the first phase, Jenova Dreamweaver has left and right tentacles, which can be crippled. While the tentacles are up, Jenova is hard to stagger. It slashes party with its tentacles, including the one behind it, which cannot be harmed. To damage Jenova effectively, the tentacles must be crippled. This puts her into a pressured state, allowing the player easier time to stagger it. The phase ends once Jenova's HP has been reduced by 1/4.
In the second phase, Jenova still has its tentacles, but takes on new abilities, such as switching places and causing harmful rain after moving, and generating a moving field, which can damage and occasionally inflicts Stop and Silence. It uses Vengeance to cause concentrated heavy damage to a single target and makes itself invulnerable to either physical or magic damage. In this phase, the moving field must be avoided, and the tentacles crippled like in the first phase. After about half of its HP is down, the phase ends.
In the third phase, Jenova surrounds itself with an impenetrable barrier and brings out a multitude of tentacles that must be taken out. The tentacles must be taken out quickly, otherwise, they can use Vengeance of their own against a single target. If there are too many tentacles, it will be a certain KO for the target. Like in the second phase, Jenova uses the moving field, but won't switch places. To harm the main body, the other tentacles bust be taken out. After enough have been destroyed, Jenova is pressured and can be staggered. The player must be quick about it, or else more tentacles spawn, and Jenova becomes invulnerable again. Once Jenova has been damaged enough, the phase ends.
In the fourth and final phase, Jenova uses a combination of all things introduced in the previous phases. The player will have to concentrate not only on attacking Jenova but the tentacles that spawn. To stagger Jenova, the player must cripple the left and right tentacles.
Aside from invulnerability in the third phase, Jenova Dreamweaver is susceptible to Poison, which can make damaging it somewhat easier, so the player can bring the poison materia. Barrier materia can be used to grant defensive buffs against Jenova's more damaging abilities.
Tifa may be a good character to use to take out the numerous tentacles that spawn around the floor when the player needs to work fast, as she is the fastest party member, and can be made even faster with the Haste spell.
"Dreamweaver" refers to it being an illusion projected by Jenova.
The "Beat" in its Japanese name refers to the prenatal heartbeat, a stage of development preceding birth. In some foreign language versions the enemy is called "Jenova Pulse" referring to the same thing.
Though named Jenova Dreamweaver in the game's final English localization, the data in the leaked demo build indicates that it was originally localized as "Jenova PULSE" at some point prior to the game's release, a name that was kept for the Italian localization (as "Jenova Pulse"). It is named "Jenova-Puls" in the German localization, "Jenova-PULSATION" in the French localization, "Jenova Onìrica" in the Portuguese localization, and "Jenova Alfa" in the Spanish localization.
