50 int is pretty comparable to 30 mab anyways. And anyways assuming you stick with ice nukes (not to hard to do) undying will help your dmg more than baying moon.
Interesting side note: Tonight for some reason my comp wouldn't stop freezing in pt. Spec wise it shouldn't be a problem it just does it sometimes.
So I decided since I had alot of lights to go and solo and get a key *** to leech. Went to worms. Turns out once I finished capping lights and got blizz 4 I could almost non stop chainspell. Ie chainspell 5-7 mobs to death get an isl rinse repeat over and over and over. Sadly since I don't have ultimate or undying I kinda had to rely on aestics to 2 shot the mobs but was rather interesting way to xp and convert timer never mattered ;)
And yes obviously sometimes bad luck happened and no isl dropped in a round. Just like sometimes 3 did and even being quick 1 would go to waste
