Re: can huskar kill himself with his ult?
Confirming it is technically possible through 0.405 hp = death silliness but grossly unlikely.
Huskars ulti does magic damage, He needs to have:
0.35*2.86 = 1 at level 1
0.3*3.33 = 1 at level 2
0.25*4 = 1 at level 3
So he needs to have 2.86 magic amplification on him as a minimum. Note that most sources (soul catcher, dirge ulti, etc) won't work as these deal seperate damage sources and thus huskar wouldn't be dealing the killing blow to himself.
Ice vortex, natural order, ancient seal, decrepify is as high as I believe you could get. That is only 1.25*0.75*1.44*1.36*1.26 = 2.31.
So there is currently no way (unless I forgot an ability) to have enough magic amplification to suicide through huskars ulti except that rare exception.
