Well, at the moment, if eliminate the leadership is in the pool, Sandeep can take :
an upgrade giving him Df6 and a one time 2 dmg reduce (that's basically 14Wd, plus soulstones),
a steamfitter that gives him armor +1 (byebye 2 dmg min, that cannot be cheated)
a steamfitter that prevent him from taking a severe (that doesn't happen, he is already ItW, but he will just laugh at your RJ)
And he still can teleport away, heal, be pushed toward a friend etc...
That makes him one of the (if not the most) thoughest master (model ?) in the game. (It can still be killed in some extreme situations or if it is caught completely out of position... but why would you do that ?)
