A T5. Cloak of Endless Twilight has the same length of cloak time but has no VIT or WIS bonuses, but also costs much less (1 DEX - 2 LIFE).
To chain cloak your rogue, you need at least a level 72 magic heal pet (9.97/s). A level 70 magic heal pet will generate enough magic to cloak many times, but losing 6 mana each time (8.68/s). Assuming you have a maxed rogue, these stats will be correct.
