Growth, Mad Growth, and Wild Growth are a series of Venus attack Psynergy featured in both games. Although the character can acquire them just outside of the first town in each game, those unfamiliar with the Djinn mechanic may not find this available. It is available to the Brute Class series (Brute onwards) and both Seer Class series (Mercury and Jupiter). As such, this Psynergy is available to any character, provided the correct Djinn combination.
Growth: “Attack with wild plants.”: This costs 4 Psynergy Points, has a base power of 25 and has a range of one target. A few thorny vines erupt from the ground and through the foe. It is available at level 1 for Brute classes and level 3 for Seer classes.
Mad Growth: “Attack with ferocious plants.”: This costs 10 Psynergy Points, has a base power of 60, and has a range of three targets. A group of thorny vines erupt from the ground and through the foes for a short time. It is available at level 12 for both Brutes and Seers.
Wild Growth: “Attack with giant plants.”: This costs 19 Psynergy Points, has a base power of 110, and has a range of five targets. A large tangle of thorny vines erupt from the ground and through the foes for an extended time. It is available at level 28 for Brutes and level 29 for Seers.
Outside of battle
The first of the Growth series Psynergies can be utilized on small plants to cause them to grow into tall vines, which Isaac or Felix can then climb to reach new areas. Another use is to navigate the maze within Gaia Rock leading to the Serpent, where the player must use Growth on the plants to see which way to go. If not used on a plant, Growth works much like in battle, but as it is deprived of a target, it is effectively useless.
As far as basic series go, the Growth series could be considered the staple area-of-effect Venus Psynergy. Early in the game, it can serve as an effective combat tool, but later in the game, Grand Gaia is generally considered more effective than Wild Growth. However, Wild Growth is obtained almost twice as early as Grand Gaia, level-wise, and can still serve well up until then.
