Ichi looks weaker!

This was the only hit on my tank the entire combat.

My tank, after the hp from AS should have 15M. 5M innate + Jigsaw cast Ablative Shield on all friendly Minions (9962319). My last minion is using an AoF so that is the hp he gets.

However, in only 1 hit his strength went from 7.78M to -10.5M.

That is quite a lot of strength lost from a really small hit.

On my old character, of which the tank had over 15.5M HP, the same hit would drain my strength from 9.6M down to about 2.6M or so IIRC.

This directly from the changelog Dude quoted:

The stat drain will be proportional to damage done. At about 2.5% of the target's current (not max) HP, the drain will be about what you were used to. At 5%, it will be 2x*, where it is capped. And on down: at 1% of HP, it will be 0.4 of the old drain. There is no floor; enchanters armed with a crossbow can expect to be very disappointed.

The damage done was about 1.3% or so of my total hp at the time. 17M drain is quite a lot.

So is there a bug not counting hp added from AS in the calculations of exbow drain?

I know that the hp from AS are not added normally since there are certain calculations in the game which differentiate innate HP from AS HP. Such as TSA regeneration as well as damage done by the MoD.
