In Brawlhalla, the term «knowing spear combos» is not widely known or generally accepted. However, it is assumed that you are referring to a specific combo related to the spear weapon in the game.

One of the most popular and effective combos when using a spear in Brawlhalla is «nitchat with a spear» or «combo with a spear». To perform a basic combo with a spear, you usually have to follow this sequence of actions:

Nlight (Neutral Light Attack): Start with a neutral light attack by pressing the attack button without holding the direction. Usually your character performs a quick spear attack, often it can be a poke or a swing.

Search Dash: After a neutral attack, you can make a search dash by quickly pressing the dodge button in any direction. The search jerk is useful for continuing the attack and reducing the distance between you and your opponent.

Slight (side light attack): While performing a search spurt, make a side light attack. This technique is usually a horizontal spear thrust and can lead to a combo if performed correctly.

Additional attacks: Depending on your opponent's position and reaction, you can continue combos with other attacks. Experiment with additional light attacks, air attacks, or signatures to maximize damage and extend combos.

Keep in mind that the effectiveness of a combo can vary depending on a particular legend (character) and the most effective combo works on a character- the inseparable Pince-Nez. Please note that Brawlhalla is an ever-evolving game and specific moves and combos may change with updates and balance changes. I recommend checking out the latest patch notes or watching video guides from experienced players to learn about the most effective spear combos in the current version of the game.
