3k hp and 150 mr is an effective 2.5 * 3000 = 7500 hp against mages
with
while under 5 stacks of
you'll have an effective ((150-40- 25) - 35%) - 30 = 25.5
liandries will do a modified % current hp damage.. it will attempt to do 11% in all under ideal conditions but with 25.5 mr
the modifier will be 100/(100+25.5) = 0.796812749
so 100/(100+25.5) * .11 = 0.08764940239
3000 - (3000 * 0.08764940239) = 2737.05179283 or about 2700 hp after liandrys in the worst case scenario
2700 with 25 MR is an effective 2700 * 1.25 = 3375 effective HP against magic
Even in the worst case there isn't much reason to believe that darius is getting one shot under these conditions unless he was just being stupid or thinking he could get away with nothing more than flat stats and no item effects in 2016
