Vlad's Impale

You call upon the nature of the legendary Vlad the Impaler. Whether your intentions are similar to his own or much more malicious, it requires a great amount of your own magic prowess to use. Such a spell can be seen as a vile or horrifying act to enact. 

The spell opens a portal anywhere within the spells range, allowing one to even hit aerial targets, as a great blackened and serrated spear of pure magical energy pierces the target. 

The target must make a DEX saving throw against your spell save DC to take full damage or half. 

The target must first make a CON saving throw DC 18 or have their hit points reduced to 0. 

The target takes 20d6 magical piercing damage and 5d8 necrotic.

The spear stays in existence for 10 minutes and if the target failed the DEX saving throw, they must make an additional STR saving throw against your spell save DC to pull themself off the spear.
