Tigyrius's Elemental Sphere

You launch an orb of magical energy that travels 30ft in a straight line each round. Any creature you choose within 15ft of the orb as it travels must make a dexterity saving throw, taking 5d6 damage on a failed save or half as much on a success. Targets also suffer an additional effect based on the sphere’s type, chosen at casting. If the sphere collides with a creature or object the spell ends early and if it was a creature, that creature must make an additional dexterity save, suffering the spell's effects again. No target may be struck by the sphere more than once each round unless it collides with them. On a following turn you may use a bonus action to pull the orb 30ft back towards your current location, however this will end the spell immediately afterwards whether it strikes an obstacle or not.

Ball Lightning: An orb of pulsing electricity flies from your outstretched hands. Bolts of lightning arc out at creatures within range dealing lightning damage and causing them to become stunned until the end of their next turn on a failed save.

Frozen Orb: As this spinning sphere of frost travels it hurls freezing icicles in all directions dealing cold damage. A creature failing its save has its movement speed reduced by half and has disadvantage on melee attacks for three rounds.

Forbidden Sun: This blazing orb sheds waves of flame as it travels, dealing fire damage and setting creatures ablaze on a failed save. These creatures take 5d4 fire damage (+1d4 per spell slot above 4th) on the following round.

Arcane Globe: Pure magical energy warps space and gravity as it moves, pulling creatures towards it or pushing them away and dealing force damage. Choose whether the orb will push or pull when casting and creatures will be moved up to 10ft in the appropriate direction on a failed save.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 and the orb lasts an additional round for every level above 4th.
