Description

Dropped by the Cake Queen in the Sea of Treats, the Buddy Sword is one of the more sought-after legendary swords in the Third Sea. Earning it means going toe-to-toe with one of the game's tougher bosses, so players should be well-leveled and bring a reliable fighting style before heading into that battle. As a sword it scales with the Sword stat, meaning every point invested there translates directly into stronger hits. Its two moves, Heat Slash and Lightning Wave, give it a dual identity — one leaning into scorching melee pressure and the other providing a ranged lightning option to punish enemies at a distance. Mastery climbs with every successful hit, gradually unlocking the full potential of both moves. For players farming the Sea of Treats or grinding Third Sea content, the Buddy Sword's legendary rarity and versatile moveset make it a strong pickup worth the effort of defeating the Cake Queen.

Trivia

1can be dodged if the target is currently dodging another hit concurrently (e.g. the target is shot with Skull Guitar , turns on Instinct, and later be shot with while dodging, thus making them dodge out of the way of the wave).
2has a glitch if the player uses the tab glitch, they can aimbot the lightning wave hitting it no matter where they are. This glitch does not always 100% work.
3The Buddy Sword can be hard to combo with, because launches the enemy pretty far away and the player can't continue the combo. The solution for this is to have the player face downwards and do the combo, causing the enemy to not go anywhere but get stuck at the ground for an open combo.

Buddy Sword — In-Depth Analysis

What Is the Buddy Sword?

The Buddy Sword is a Legendary sword exclusive to the Third Sea, obtained as a drop from the Cake Queen boss in the Sea of Treats. Its candy-realm origins fit its unusual mechanics: it's a sword that rewards precise prediction and punishes reckless swinging. Crucially, it provides a passive healing effect while equipped, which is a rare and genuinely valuable perk in prolonged fights.

Strengths, Weaknesses, and Who It's For

The Buddy Sword has a fast M1 click speed with all moves being very fast and difficult to dodge — a strong PvP foundation. Its damage increases as the enemy is farther away, rewarding patience and spacing rather than raw brawling. The passive heal is a genuine survivability bonus, especially during boss runs or while AFK grinding. A tripwire-like effect on its X move can catch opponents off-guard.

Weaknesses are significant for aggressive players: moves deal major knockback that hinders combo building, single-target skills won't hit Sea Beasts, and the hitbox is small enough that precise aim is mandatory. It also can't hit Blade users and offers no mobility moves.

Tip: Treat the Buddy Sword as a spacing and kiting weapon — stay at mid-range, let the damage-at-distance bonus stack, and use the passive heal to sustain through longer engagements.
