A. Pros and Cons:

Pros:

Exceptional initiation potential with his ultimate, Cataclysm.
Strong crowd control with his EQ combo and ultimate.
Good base stats and dueling potential.
High mobility due to his Demacian Standard and Dragon Strike.
Versatile build options.
Fits well in various team compositions.
Cons:

Relies on landing skill shots for maximum damage.
Vulnerable to crowd control and kiting.
Can be mana-hungry in the early game.
Limited ranged damage output.
Requires good decision-making to engage effectively.
B. Abilities:

Martial Cadence (Passive):

Jarvan IV's basic attacks deal bonus magic damage to the target equal to a percentage of their current health. This passive ability makes him a strong duelist and allows for healthier jungle clears.
Dragon Strike (Q):

Jarvan IV extends his lance in a straight line, damaging and reducing the armor of all enemies hit. When the lance collides with an enemy champion or the Demacian Standard, Jarvan IV can use his next ability, Golden Aegis, to create an area-of-effect slow and shield.
Golden Aegis (W):

Jarvan IV creates a slowing field around him and gains a shield based on the number of enemy champions hit. This ability is great for engaging and surviving in fights.
Demacian Standard (E):

Jarvan IV tosses a Demacian Standard to a target location. When the standard lands, it provides vision, grants bonus attack speed to Jarvan IV and nearby allies, and enhances his Dragon Strike's damage and armor reduction when used in conjunction.
Cataclysm (R - Ultimate):

Jarvan IV leaps to an enemy champion, dealing damage and creating a terrain that traps both him and the target inside. This ultimate is a game-changing tool for initiating fights and isolating key enemies.
