Similar to the Fireweaver Bomb, but much much better. On impact it causes ice shards to appear that freeze enemies that touch them and do high damage. The spikes last for a decent amount of time but beware as they damage you heavily if you run into them. Very powerful, fast fire rate, and rather low mana usage because of how powerful it is. Secondary fire launches more bombs so you can cover a wider area. Being a grenade it may be hard to hit far away enemies, and it also does nothing to flying enemies (unless you hit them with the initial impact, but that is a waste of mana. Only the Firestorm Grenade can reliably damage flying enemies).
