A bag of slime seeds. This'll cause more slimes to appear.
Accelerates Slime Growth
By changing the diet of the slimes you can make baby slimes grow up faster.
By integrating turbines inside of slimes, you can increase the rate at which each slime charges the crystals.
Slimes are naturally slow to mate, leaving very few left over wave to wave. More fecund slimes allow for more slimes already at your crystal at the start of the wave.
Increasing how slippery the slimes are allow them to move across the stage more quickly.
Hard hats can protect slimes from impacts.
The seeds were planted more precisely, so that slimes spawn more closely to the crystal.
Adding rocks to the fortress makes it heavier, which makes it fall more forcefully.
Congratulations, you charged the crystals!
