The Basics
•Location: Enkanomiya: You can find the Primo Geovishap at specific points within Enkanomiya, an underground region beneath Watatsumi Island in Inazuma.
•Appearance: The Primo Geovishap is an enormous dragon-like creature that features crystalline structures, particularly around its body, which glow with a geo element.
Combat Mechanics
•Elemental Resistance: It has a high resistance to Geo damage but can be affected by other elements to varying degrees.
•Crystal Shield: It often starts with a geo shield that needs to be broken before significant damage can be dealt. This shield can be destroyed by breaking the smaller geo structures surrounding it.
•First Phase: The boss will have its shield, and breaking it transitions to the next phase.
•Second Phase: The Primo Geovishap will start to use more aggressive attacks, including geo-based area-of-effect (AoE) attacks and projectile launches.
•Elemental Vulnerabilities: After its shield is down, it becomes susceptible to elemental reactions, particularly those that don't involve Geo.
•Crystal Spikes: Summons geo spikes from the ground.
•Geo Blast: Fires a large geo projectile.
•Slam Attack: Uses its body to slam the ground, creating shockwaves.
Strategy 
•Break the Shield: Focus on destroying the geo structures around it to remove its shield.
•Elemental Reactions: Use characters that can trigger elemental reactions other than Geo to maximize damage.
•Dodge and Positioning: Pay attention to the boss's movements and attacks to avoid damage. Its telegraphing for attacks is quite clear.
Rewards
1.Defeating the Primo Geovishap can yield various rewards including:
2.Primogems

Tips: 
•Bring Healers: Given the boss's powerful attacks, having a healer or a character with good shields can be beneficial.
•Elemental Mastery: Characters with high Elemental Mastery can benefit from the reactions, especially if you're triggering things like Swirl or Electro-Charged.
The Primo Geovishap is not only a challenging fight but also visually spectacular, making it one of the more memorable boss battles in Genshin Impact.
