Smitebase numbers could be wrong, but if they arent then the only item on this build that lost HP was Ancile and it only lost 50, so Im not sure why it would be a loss of 200. The flash test will show for sure though.
I know full notes are not out yet, but the intent for that was
Ancile - 50 Health off
Runeforged Hammer - 50 Health off
Mystical Mail - 100 Health off
Each of these also had other nerfs (like HPS off Runeforged as well as it losing strength and costing more).
