Casting Time: 1 action

60 feet Components: S, M (A small ice shard)

S, M (A small ice shard) Duration: Instantaneous

A small ice spike appears between your finger. Make a ranged spell attack against a target that you can see within 60 feet of you. On a hit, the target takes 2d10 cold damage and its speed is reduced by 10 feet until the end of its next turn.

On a critical hit, the spike goes through the target and can hit another one if it is somewhere in a 30 feet line behind the initial target. Make a second ranged spell attack to see if it hits. The spike can only go through one target maximum.

At higher levels: The damage increases by 1d10 for each slot above 1st.

Frozen grounds

???-level invocation

Casting Time: 1 action

1 action Range: 90 feet

90 feet Components: V, S

V, S Duration: Concentration, up to 1 minute

The ground instantly freezes in a 30 feet radius of a point that you can see. The area becomes difficult terrain, and you can add one of the 3 following effects:

-Small ice needles cover the ground. Any creature moving through them must succeed on a Dexterity saving throw against your spell DC, or must take 1d4 piercing and 1d4 cold damage every 5 feet on the affected ground.

-When the area spell is casted, every ennemy creature within the spell's area must succeed on a Constitution saving throw against your spell DC. On a failure, the ice spreads from the ground onto their legs and their speed is reduced to 0. This effect ends if the spell ends, or if they succeed on another Consitution saving throw, which they can make for free at the end of their turn.

-If casted on water, the area increases to 60 feet (if there's enough space) and instead of being a difficult terrain, the spell creates a block of ice that is 2 inches thick and can be walked on. After the spell ends, the block melts instantaneously.
