Shiro Solo/Shiro Tank (A/Mo)

I've beaten Shiro on Hard Mode solo at the Imperial Sanctum (with Mhenlo, obviously) with this build, and I've tanked very successfully in the Gate of Madness with this build (I even handed it to another assassin who modified it slightly, but it still worked beautifully):
Jagged Strike Wild Strike Death Blossom Critical Agility Vigorous Spirit Critical Defenses Way of the Assassin Critical Eye
Attributes:

Healing Magic: 8
Dagger Mastery: 12 +2
Critical Strikes: 10 +1 +2

Usage: When about to tank shiro, run up to just outside his aggro range, activate critical agility, vigorous spirit, critical defenses, way of the assassin, critical eye, and immediately charge in.

You MUST keep critical defenses up at all times. Keep an eye and try to keep up critical eye, way of the assassin, and vigorous spirit. However, in both cases will need additional healing support (in Imperial Sanctum, Mhenlo) to make up for all the attacks (With 75% block, 100 attacks a minute from Shiro, at least 25 should get through). One healer is enough. Also, keep Mhenlo or the healer far enough away from Shiro when he uses impossible odds.

The skill critical eye can be removed for variation and still be ok. Many of the skills can be changed, but you will not deal as much damage as may be necessary. You can also switch to A/D and use Mystic Regeneration in place of vigorous spirit as well, but I haven't tried that.

This build does deal enough damage to deal with impossible odds and meditation of the reaper.
