This is a crystal ice thrower available to levels 46 and up, as usual we will be looking at its efficiency by comparing it with the weapon closest in level both below, and above it. (Note* The image was taken during a sale and does no reflect current prices.)
So beneath this weapon level wise is the crystal ice thrower the Enveloper, available to levels 41 and up. It does 40 damage, has a speed of 94, and has a Slow of (10) for a weapon ability.
The White Dragon beats out the damage by 5, the speed by 3, and changes out the Slow(10) to a Freeze of 5%. The Freeze ability can be severely jacked with equipment, but even without that just based on speed and damage the White Dragon is viable upgrade.
The next ice crystal weapon up from the White Dragon is the Yeti's Bane available to levels 55 and up. That weapon packs a 47 Straight Damage, 99 Speed, and the same Freeze at 5%. So you gain 2 to damage, 2 to speed, and keep the weapon ability as is. So the weapon above the White Dragon seems to pack only a slightly better damage and speed for an 8 level gap between the two weapons.
Overall looking at both what is below, and above the White Dragon I have to say it is a solid weapon. Seated within the two level ranges but leaning heavily towards the higher of the two.
