Algae Bloom

The caster summons a bloom of algae, burning the skin of any foolish enough to touch it. The caster specifies a point within range and casts the spell. Any creatures within 5ft of the spell must make a DEX saving throw versus the caster´s DC. On a fail they are enveloped as magic and the rotting fertilizer help the algae explode with growth. The target takes 1d8 acid damage and are poisoned. After the explosion the algae dissipates and is gone. While poisoned, the target must make another CON saving throw each turn, taking 1d4 acid damage each turn. A Greater Restoration spell or similar magic can remove the effect.
