User blog comment:V3hemenc3/Runic Bulwark and who on your team should build it/@comment-5889958-20130201191413

With the aura mechanics, right now, if 2 can build it from the team, then both of them should.

E.g.: jungler do it, and support also, meaning that jungler will get twice the aura, which is kinda  nice for initiate

But this can work with any other aura items, like your vlad got WotA, then your support can buy it as well if he/she is AP type (sona/janna/etc), so both get 60 AP and 40% spell vamp.

Zeke also, perfect item for supporting adc, but many top solo are a good candidate for it, 40 AD and 20% lifesteal for both.

Etc, etc.

Tho not always good to "stack" same aura items, with some common logic, teamplay, you can see if it is worth it, or not. Ofc, in the 95% of time, 2 of you shouldnt focus on the same item as first item, since diversity is more efficient usually. But, if the game is long, then the aurastacking is a good thing, since it enhances the same aurabearers, and usually support will be the auraspammer.
