The Swift Potion is arguably the most efficient potion in the Deepwood Groaks’ arsenal. With a cost of 0 Magic, it offers tremendous value, even if that value isn’t immediately apparent. One of its strengths lies in its flexibility—you can brew a 5-boost Swift Potion early on and keep it as a tool or a lingering threat to your opponent. While it’s active, all your units can move 3 spaces, which is particularly beneficial for Bloom Warriors.

The real power of the Swift Potion comes from the tricks it enables. For example, you can attack with a unit, then use the Swift Potion to move it away, creating space for a ranged unit to attack through that opening. With ranged units, you can strike and then retreat to a safer position. You can also kill a unit in melee and immediately occupy the space it vacated, which can be crucial for controlling gate spots or flanking an enemy summoner.

Essentially, the Swift Potion offers all the tactical maneuvers common in Summoner Wars that involve forced movement—on demand and with up to 5 uses. Mastering the Swift Potion is essential for Deepwood Groak players, and brewing at least one per game is highly recommended.

One general rule for potions, not just the Swift Potion, is to be cautious about using them with fewer than 5 boosts. While there are scenarios where using a potion for less might be worth it for the tempo advantage, as a rule, aim to play potions with at least 5 boosts, or at the very least 4.
