Boomerang

Description
Fires a boomerang forwards that returns on the same row whenever it passes through the field entirely. Any target hit is dealt 50 damage and is for 2 seconds. Whenever a target is hit, the player gains back up to 2. Despite the wording, the player can gain more Mana than they expended casting this spell. The Mana gain can also trigger off of the same target twice, meaning both hits on cast and on return can each restore 2 Mana for the player.

Strategy and Synergy
Since this spell pays back for itself as long as it hits an enemy and perhaps even more, it is a great Mana-generating machine that also deals a decent amount of damage. Not only that, it applies Root to the target hit, meaning the returning attack is almost guaranteed to hit if the first initial throw also successfully hit the enemy. To make the most use out of the Mana-generating capabilities of this spell, the player should try to line up as many enemies at once as possible while also casting other spells as the boomerang projectile is travelling to use up all the Mana generated before letting it go to waste by hitting maximum Mana. Alternatively, the player can simply wait when they are at a low threshold of Mana before casting Boomerang.

increases, previously wasted excess Mana to be generated. The increased Mana gain can also help the player to play out the remaining in the deck after casting Innervate. Since a lot of Mana can be generated with this spell alone, it and Innervate synergizes very well together with that acts as a Mana sink. Considering that it also roots the enemy in place, it ensures that all shots will hit the target.

The best upgrade for this spell is because despite the reduction in Mana cost, the Mana generation and the application of Root is not affected at all, unlike the case with. Alternatively, the player can opt to go for or  instead if they want Boomerang to still deal a decent amount of damage.

In a heavy Convergence deck that utilizes to repeatedly cast spells one after another, Boomerang plays the role of immobilizing the enemy to allow the stream of Mana generation to continue. This is because with instant shuffling and lots of mana generation, it is likely for the player to cast a second Boomerang on a new shuffle before the Root from the previous even wears off.
