Recently I enchanted a few items to basically get my Magicka as high as possible, while currently wearing Adept Destruction Robes. With all my enchanted apparel my Magicka pool is up to about 440 (I didn't exactly go for a Mage character off the bat).

However, I've noticed that if I'm wearing all these items and casting any Wall of- spell - I can basically do it forever/until I die. Even when my Magicka bar appears empty, if I just keep holding down the spell it will keep casting. The only Magicka regen helpers I have are the Recovery 1 perk and the 150% I believe that the Adept robes help. But with my previous experience the Wall of- spells won't even cast (but will take your magicka) if you try to cast them with a minut amount of Magicka.. and I doubt I'm regenerating Magicka fast enough to supply a 80-100/second spell (with the Expert Destruction perk). Soooo.. is this a bug that should be moved to the other forum... or is this some 'acceptable' or logical thing?

magicka doesn't regenerate when you are casting a spell

So is bug? k.
