Sentinel: +2 Duration gems +2 AOE gems Tabula

I lucked into this in a low level Temple after debating if I should give some gem a few more percent quality and struggling to figure out how to actually use the Locus on console.

Looks like it's a big ticket rare item. In PC Sentinel there's only one for 45 EX on Standard some for 8-10 EX and then sky's the limit. I put it up for 8 EX on Playstation trade now. Don't know how realistic that is but we'll see.
I'm also tempted to use it as the ultimate twink item and level something like cold dot or Fire Trap.
