Stinger

Strategy and Synergy
Does around the same amount of damage as Shield Throw, but with a few upsides. One of the largest benefits is that it doesn't leave you open when you cast it, and it doesn't have a risk of losing all your shield if you miss it or move away. This card also has homing capacity, meaning that you don't have to aim it. The fact that it fires a large number of projectiles also means that spell power makes it much more powerful, with each point of spell power increasing its damage by 10%. However, its high mana cost makes it much harder to cast, and the Calamity rarity means it rarely shows up. Overall, this spell can add a massive amount of damage and security to a strong shield build, if you can afford it.
