Rubber to Gold (BTDB2)

"Converts all bloons partially into gold, giving you cash for each pop from affected bloons."

- BTDB2 description

Rubber to Gold is the 4th upgrade on Path 3 of the Alchemist in Bloons TD Battles 2. Because popped bloons do not give cash by default, instead of bonus cash like its BTD6 counterpart, affected bloons give $1 per layer popped.

It costs $2750, and requires 8500 XP to unlock.

Summary
Rubber to Gold's cash generation relies on splashing goldifying potions onto bloons. In practice, it works better than Bloon Trap against higher-tier bloons and if bloons are stalled, as with BTD6. However, it throws goldifying potions quite slowly.

Tips

 * The preferred crosspath is with Larger Potions, in order to gold more bloons for more money. However, Acidic Mixture Dip is not reccomended since it makes it harder for Rubber to Gold to utilize its Lead to Gold upgrade against leads. Stronger Acid and Perishing Potions are discouraged, since popping the bloons faster gives them less time to be golded.
