• Increases damage by 25%.

• Bluer Guon Stone - If the player also has [Blue Guon Stone] , the rotation speed of the Guon Stone is increased. If the Guon Stone blocks a bullet, it deals 15 damage to all nearby enemies.
• Clearer Guon Stone - If the player also has [Clear Guon Stone] , it grants immunity to poison, fire, and electricity. Shooting enemies while standing on fire or ice will burn or freeze them, respectively.
• Friend to Gun and Bullet - If the player has [Potion of Gun Friendship] , while it is active, a copy of the player's current gun appears and automatically fires at nearby enemies. The copy of the held gun fires faster than normal but with reduced damage, especially if it is a rifle-style weapon.
• This synergy affects the [Prize Pistol] while playing [Winchester] 's mini-game, and the shots fired by the copy do not count against the player's allowed tries.
• Before the A Farewell To Arms Update, If the player drops [Potion of Gun Friendship] while the synergy is active, the copy gun is permanent. This can be done repeatedly to amass a large amount of orbiting guns.
• This synergy works even if the weapon used is out of ammo.
• This is best utilized with weapons such as the [Dueling Laser] , which will fire multiple shots in succession without needing to recharge. The copy gun carries over to the Past.
• The copy gun can reveal secret rooms (unless it is an infinite ammo weapon or another kind of weapon that cannot normally reveal secret rooms).
• The copy gun fires all types of the guns bullets at once (e.g. fires all three levels of [Polaris] at once).
• Greener Guon Stone - If the player also has [Green Guon Stone] , the stone's chance to heal the player is raised to 70% if the player is one hit from dying and 20 also appears whenever [Green Guon Stone] heals the player.
• Nailed It! - If the player has [Nail Gun] , its nails deal triple damage.
• Oranger Guon Stone - If the player also has [Orange Guon Stone] , it shoots twice as fast and deals 8 damage rather than 5.
• Pinker Guon Stone - If the player also has [Pink Guon Stone] , enemies that damage the player become temporarily charmed.
• Pistol Machine - If the player has [Machine Pistol] , its shots pierce enemies and are connected with electricity.
• Redder Guon Stone - If the player also has [Red Guon Stone] , the player gains a yellow glow and stat increase similar to that of the [Macho Brace] for a short time whenever the Guon Stone blocks a bullet.
• Reinforced - If the player has [Lower Case r] , the voiceline and burst will spell BULLET+1 when fired.
• Whiter Guon Stone - If the player also has [White Guon Stone] , [Daruma] 's recharge is halved. However, [Daruma] itself is not part of the synergy.
• In addition to their unique effects, all -er Guon Stone synergies increase the size of the Guon Stone and make it rotate at a fixed distance from the player while they are moving instead of on a slight delay.
• If duplicates of this item are somehow obtained, further increases the damage of the player's bullets.
