Rubble

Rubble is the left over product of a tower after death or destruction. Different kinds of towers leave different kind of rubble. Towers cannot be placed on rubble, but they can be removed and, when removed, give you some crafting materials for your trouble.

Rubble Types

 * If a living tower dies a grave appears in place of it.
 * If an agent dies other than a mad snowman then a golden grave appears.
 * If a non living tower is destroyed rubble appears. When a monkey buncaneer (0/0-x/4 only) is destroyed driftwood appears.
 * When a mad snowman dies it leaves a snow pile.
 * When a pro mad snowman dies a large snow pile appears.
 * If an air tower dies wreckage appears.
 * If a Bloonsday Device is destroyed radioactive waste is spawned. Why is there rubble in the first place? Well, certain crafting materials are only found in specific types of rubble and towers cannot be placed on rubble.
 * When a sun god dies it leaves a sun alter.
 * When a TOTMG is destroyed a sun spirit is released.

Rubble Removal Costs

 * Rubble costs $650 to remove.
 * Gravestones take $200 to remove. But, when a gravestone is removed, all towers shoot 10% slower for 1 and 1/2 rounds. The effect does not stack, but the time does.
 * Golden gravestones are free to remove and give $500 as a way of making up for the lost agent.
 * Snow piles take $550 to remove, but melt in 3 rounds without action.
 * Big snow piles take $850 and 1 round to remove, but can melt without payment in 6 rounds.
 * Wreckage takes $800 to remove.
 * Radioactive waste cannot be removed with money. It is destroyed by a super monkey storm or grade zero.
 * A sun alter costs $1300 to destroy and all sun gods will stop firing for 20 seconds. This does not stack.
 * Sun spirits can not be removed, unless truly evil actions are taken.

Rubble Effects

 * Rubble, gravestones and wreckage provide no change to surround towers.
 * Gold gravestones boost rate of fire in nearby towers by 20%.
 * Snow piles and big snow piles slow rate of fire by 15%.
 * Radioactive waste does 2 damage every 5 seconds to nearby towers. But, if a dart monkey dies because of this, there is a 20% chance of it becoming a Mutated Beast.
 * Sun alters make all towers nearby able to pop leads and frozen bloons.
 * Sun Spirits can be placed on. But, only super monkeys can do this. When this is done the sun god upgrade cost is lowered by 45%.
