Is a flail degrade

To my knowledge, there are only two flails in-game. One of them degrades over time, however the other will only degrade through continued use of its special attack.

1. Verac's Flail, a possible Barrows reward, degrades over the duration of its use in combat.
2. Ivandis Flail is not degradable, however it will degrade with the use of its special attack against Vyrewatch. The downside to this flail is that it requires quests' completion before it can be used (Legacy of Seergaze and previous quests in the sequence) and it is not as strong as Verac's Flail; this one being best used against Vyrewatch. Be warned: the Blisterwood weaponry is obsolete when compared to the Ivandis Flail, though there are currently no flails available composed of Blisterwood.
