Cursed Acid Splash

Cursed acid boils with rage and has a dark purple color.  It melts through things at an amazing speed, and you can almost feel the aura of heat that it gives off.

You hurl a bubble of cursed acid. Choose one, two, or three creatures you can see within range. If you choose two or three, they must be within 5 feet of each other. A target must succeed on a Dexterity saving throw or take 2d6 acid damage.

When casting this spell, you must succeed on a Intelligence (Arcana) saving throw or take 1d6 acid damage.  You take half as much on a successful saving throw. 

This spell’s damage increases by 1d6 when you reach 4th level (3d6), 9th level (4d6), 14th level (5d6), and 18th level (6d6).
