Converts all Bloons partially into gold, getting more cash per pop from affected Bloons.
~ BTD6 description

Rubber to Gold is the fourth upgrade of Path 3 for the Alchemist. It allows potions thrown by the Alchemist to partially turn bloons and MOAB-class bloons (except the BAD) into gold, increasing income from popping them.

It costs $2335 on Easy, $2750 on Medium, $2970 on Hard, and $3300 on Impoppable.

Description[edit | edit source]

Rubber to Gold will add an extra attack that turns bloons partially into gold. Affected bloons will appear slightly golden; these bloons will earn +$2 income for all layers popped (except for MOAB-class, where only the outer layer is affected). Its special attack comes out every 5 seconds and can hit up to 15 bloons. The gold effect lasts for 5 seconds and soaks through bloons but not blimps. It is important to note that the cash modifier is additive.

Fully instakilling MOAB-class bloons (specifically via Monkey Pirates, Pirate Lord, or XXXL Trap) will triple income gain, instead of adding +$2 per pop to only the outer layer.

Rubber to Gold also retains its Lead to Gold special capability, whereby popping lead bloons with this Alchemist in any way will give an instant $50. Leads can still be affected by Rubber to Gold; when they are affected by Rubber to Gold, popping them will earn triple the normal income but cannot triple the Lead to Gold bonus.

The Rubber to Gold Alchemist will now dress up as an early English alchemist. Additionally, his goggles and eyes both become golden in appearance. The artwork features that alchemist revealing a golden-looking liquid potion.

With the Path 1 crosspaths, Larger Potions adds a large backpack on the monkey's back, while Acidic Mixture Dip adds an bucket of acid on the right-hand side of the monkey's backpack. With Path 2 crosspaths, Stronger Acid changes the acid in the bottle to purple and gives the Alchemist white gloves, while the Perishing Potions upgrade gives it a black facemask and black gloves.

Tips[edit | edit source]

  • Setting Alchemist to Strong will make them target the bloons who provide most cash since the effect soaks through all layers.
  • The Acid Pools set up by the Alchemist will not apply gold.
  • MOAB-class bloons that are affected by Rubber to Gold give triple the income when hooked in by Monkey Pirates or Pirate Lord. Likewise, trapping an affected MOAB-class bloon into an XXXL Trap will provide triple income once full and collected, on top of a 2x bonus if collected manually.
  • Towers that can help clump up and/or slow down bloons are extremely effective as they increase the amount of bloons affected by the slow firing Rubber to Gold potion.
    • Glue Hose has excellent coverage making it one of the more effective choices for this role. As a bonus, it does not pop bloons (slow enough with Corrosive Glue), allowing Rubber to Gold to apply its effect to more bloons.
    • Likewise, Bloon Sabotage ability is a decent option, but not as good as Glue Hose. However, it is global and will immediately slow bloons upon activation.
    • Arctic Wind can be used to clump up bloons, especially Ceramics, but comes at the cost of dealing some damage to nearby bloons. Place it not too close to the beginning of the track, and place around a suitable corner to allow the splash radius of the Rubber to Gold attack to maximize pierce. The 1-3-0 Arctic Wind is usually the more useful upgrade for this purpose.
    • Knockback can be used to slow progress of Ceramics, but it can deal quite a lot of damage to normal bloons. Place it away from the start and use it as a general cleanup tower after Rubber to Gold is applied to bloons nearer the start of the track. Set the Super Monkey on Strong so as to target the stronger bloons. 0-3-2 Robo Monkey set on Strong and Close or a 0-2-3 Dark Knight set on Strong are probably the best options for these purposes.
  • The best crosspath for Rubber to Gold is 1-0-4. 0-2-4 is stronger at offense, but it loses out on potential income gain through a larger splash radius for its goldify attacks. 2-0-4 is weaker because it can potentially cause nearby towers to pop Lead before the Alchemist has a chance to use the Lead to Gold effect.
