What is the primary function of targeting spells in Riftbound?

The primary function of targeting spells in Riftbound is to affect specific units or locations on the battlefield. These spells are designed to provide strategic advantages by allowing players to directly influence the gameplay. By targeting specific units, players can disable threats, enhance allies, or manipulate the battlefield in ways that can turn the tide of confrontation. This strategic element is crucial for executing plans and countering opponents' strategies, making targeting spells a key component of effective gameplay.

Other options describe functions that, while relevant in other contexts, do not specifically align with the role of targeting spells. For instance, increasing hand size, healing units, and drawing additional cards are actions that serve different strategic purposes in the game but do not specifically relate to the targeting mechanics of spells. Targeting spells, on the other hand, focus on direct interaction with the game's elements, making them indispensable for tactical maneuvers.
