theres only one, icebrand. and this one also has a alot of atk and acc, while icebrand will be used in units like fryevia, for increased dmg on skills because of the +30 ice dmg, this one is focused on physical atk on ice units.
But I agree with the first Anonymous: I don't quite see the point. For most units, the +8 ice attack is going to be a waste. Also, at level 50 it's similar to a Nagnarok +5; the big difference is that the accuracy goes all the way up to 20, but the slash attack is only +8, whereas the Nagnarok gives you +15.
Stats gain is RNG, so you maybe need seals or hammer to max all stats.
The material to awaken *5 this sword is rarely get from Ice Chocobo Expedition. You will need to rerun the Midnight Deep twice (first rerun no cost, second rerun cost 500 vis). If you play slow then better get the material later on ice expedition, but don’t expect to be so soon for *5 awakening..
