Move Creation Workshop

[Takanomiya Hijiri]

Here are my recommended changes for your move, Hecate (in bold):

Shard Storm (300) (Ranged/Area of Effect)
A ranged attack that Hecate must charge for 10 seconds and expend a considerable amount of energy to use. This attack creates a two foot wide ball of ice that hovers at about 8 feet off the ground. After charging, the orb of ice shoots forwards up to 40 feet, at the speed of a crossbow bolt, before cracking into 24 sharpened shards which move just as quickly. Impaling targets in a 10 foot wide circle. The shards of ice are durable enough to easily pierce steel armor, and will remain present after the move has been used until shattered or melted. The orb has a maximum range of 40 feet, and will shatter immediately if it strikes its target directly. Hecate must remain stationary whilst charging this move and cannot use any other moves at the same time, as it requires her full concentration. Taking damage whilst charging this move will interrupt her and cancel the charge.

I've removed the summary lines, as those are somewhat pointless, due to most of the information there being already included in the main description of the move.

What wasn't included, I have added in, with the exception of the two uses per fight part, as that makes little sense in the context in which you gave it; the mention of it alongside stamina implied that she would not have enough energy to use it more than twice without exhausting herself... but because of the way it was phrased, you could have technically gotten away with buying numerous moves with the same two-use limit and using all of them twice per fight... which would have almost certainly cost you points when the fight was being judged.
In order to keep from being tempted to overuse moves, I would recommend simply sticking to vaguer  terminology (e.g. 'a considerable amount of energy') and trying to be realistic about it when writing the move in fights, rather than assigning specific limits to the number of times a move can be used.
That said, if you do want to add the two-use limit back in, it will probably still get approved.

I've also made a few other changes to add in required information and make certain things clearer. Someone else (probably Ebony/Dane) may have further suggestions, but I would say this is likely approvable as-is.
