Bug: Gem Bomb Upgrading

(Credit to Mavriniac for bringing this up)



It is possible to upgrade your gems for a much lower mana cost by following these steps:

1. Create any Grade 1 Gem and plant it into a tower.
2. Create another Grade 1 Gem (this one will be upgraded) and keep it in your inventory.
3. Hover your mouse over the tower with the Grade 1 Gem.
4. While keeping "Shift" pressed, press "B", then press "U". Repeat this step a couple of times and you will notice that while the gem's grade increases, only little mana is spent (the update cost from Grade 1 to 2)

The gem planted in the tower determines the mana cost of upgrading the gem in your inventory.

With this bug, you are able to create immensely powerful gems pretty much at the start of the game.

Gem upgrade Macro

# **Requirements**

- Download and install **AutoHotkey**
- Create a new script in AutoHotkey and paste the following code:

```
e::
Send, {Shift down} ; Hold down Shift
Send, b ; Press b
Sleep, 4 ; Delay between key presses (in milliseconds)
Send, u ; Press u
Send, {Shift up} ; Release Shift
return
```

# **How to Use the Macro**

1. **Prepare Your Gems:**

    - Place a gem in a **tower, trap, or amplifier**
    - Have a **level 1 gem** in your inventory

2. **Hover Over the Placed Gem**
3. **Press "E"** to duplicate and upgrade the gem
4. **Repeat Until You Run Out of Mana**
5. **Sell the Gem & Repeat**

## **How to Change the Key Binding**

If you want to use a different key instead of **"E"**, simply replace the first line (`e::`) with your desired key.

For example:

- **Change to "F"** → Replace `e::` with `f::`
- **Change to Mouse Button 4** → Replace `e::` with `XButton1::`
- **Change to Spacebar** → Replace `e::` with `Space::`
