The great mothers apply doomed on an enemy and whenever that enemy takes a turn, their health is reduced by 20%. The zeta on the basic also reduces max health if the target is doomed.
When fighting in ga with gm lead, morgan and night trooper against traya, nihulus and sion, the max health reduction did not apply. All zetas on all characters and an omicron on traya.
The screenshot was taken after 4min of doing basics with gm on nihulus.
