Hey gang, maybe a new question here.
I found an IK maul with two sockets on it. Can I add sockets from the Act 5 dude or am I maxed out there? Also, besides Shael, what else should I toss into this thing? I’ve found some great ideas from previous forums but I’ve only ever found IK maul with NO sockets so idk how to maximize this.
Cheers 
Larzuk doesn’t add sockets to socketed items. And you have to put shaels in both of those sockets otherwise you won’t hit the last WW BP.
All IK mauls always have 2 sockets.
If you are playing WW barb you need at least another 30% IAS to hit the last WW BP. So that’s 2x shael runes (40%) or 2x 15% IAS jewels. Or some combination of the two.
The jewel option is kind of neat since you can get other mods with the ias, but shael is common since they’re cheap and you probably don’t want to blow expensive jewels on an IK maul, like 40% enhanced damage/15%IAS would be awesome but probably a waste unless you’re super rich.
