To get sprouts of higher levels, up to the level 5, you need to merge them, using the Sprout Merge Panel.
To merge sprout is simple:
- Check if you have at least 3 sprouts of same level for the same plant
- Get the Colored Cards set in the Plants List for the level you have (Need to be the plants list, not the sprouts one)
- With the cards ready, just touch the panel. The result is almost instantaneous, and you will get one sprout of same plant for the next level
Example: you have 3 sprouts for Spind at level 0, and you want a Spind of level 1. Assembly the cards for Spind level 0 and touch the panel. The 3 sprouts of level 0 will be removed from your inventory, and one of level 1 will be added. And you will receive 2KPs.
The merge will take one energy, and will give KPoints with value being 'new level * 2'.
