How to chance a Spine Bow to Voltaxic Rift ?!

So I have been asking this around the game for some time and strangely enough, I got different answers:

*It doesn't require any specific iLVL to chance it
*It requires to be atleast iLVL 71 to chance it
*It requires to be atleast iLVL 74 to chance it
*http://pathofexile.gamepedia.com/Voltaxic_Rift Here it says that an iLVL 78+ is required for the bow to be chanced ?

I would like some clarifications pls, since I can't find any right answer...

The reason that I want to know this is because I would like to chance this baby if I don't sell it in the mean-time: (it's iLVL 66)

It used to be the case that you needed at least the ilvl that corresponded to the required level of the unique.

Then, they changed the required level of some of the uniques, so they became map-only. This also made them impossible to chance on items lower than that.

Then everyone complained that that sucked balls, so they removed the requirement for ilvl when chancing in a recent patch. So, now, you can chance it from any base item regardless of ilvl. At least, that's what the patch notes say now.

EDIT: ptach notes:

I think it's enough. They removed iLVL requirement in one of previous patches. Now it should require only correct base item, so any spine bow should do the trick.

Prepare your 2k chance orbs and 2k scouring orbs :D

Understood, thank you all :)
