Elemental Totem

Elemental Totem:
When Cast, you first use 1 Action to place a totem down and then for the the first 'attack' in the same round you can use a bonus action to cast the spell. For the following turns it costs 1 Action to cast the spell. Up to 3 totems can be out at once. A totem can be dispelled but also has 5 HP, it's immune to attacks from it's element but takes extra damage from it's counterpart.
Whenever you dispatch a totem, you get it back for a new cast, but if another creature deals enough damage to your totem, it is destroyed. Spells like mending can repair it.

You choose one element when placed:

• Fire (a burnt coal): You hurl a mote of fire at a creature or object within a range of 30 feet. Make a ranged spell attack against the target. The target makes a Dexterity saving throw. On a hit, the target takes 2d8 fire damage, half on a successful save. A flammable object hit by this spell ignites if it isn’t being worn or carried. You can cast this attack once every round until the totem is dispatched.
• Water (a flask of water): You protect yourself with a watery barrier. You can use it to absorb 1d6 fire and acid damage but you take 1d8 extra damage from thunder or lightning. You can also disperse it and create a big ice-cycle, hurling it at a creature within a range of 30 feet. Take a ranged spell attack against the target. The target makes a Dexterity saving throw. On a hit, the target takes 1d10 cold damage, half on a successful save. Additionally, you can create a storm centered on a point within 30 feet and a 40-foot-radius cylinder. The barrier works until the totem is dispatched, the attack can only be used once and ends the totem's effect regardless.
• Air (a bag of air): You disperse fog and other cloud types that will disappear with a wind of 10 miles per hour. It also give you quick reactions, your Dexterity modifier is temporally increased by +2. This effect works until the totem is dispatched.
• Earth (a pinch of dust): You make a 3 foot wide, 1 foot thick, 4 foot high wall of stone that blocks line of sight and any spells that would be blocked by terrain. You can create a barrier to protect your body from 1d4 bludgeoning and force damage. Additionally, you can create rock-cycles to shoot at a target within a range of 30 feet, 3 projectiles are created. Take a ranged spell attack against the target. The target makes a Dexterity saving throw. On a hit, the target takes 3d4 cold damage, half on a successful save. The wall and barrier work until the totem is dispatched and are interchangeable, the attack can only be used once and ends the totem's effect regardless.
