Extra regeneration in day shift

Level 12
Jun 2, 2012
I would like a spell in which blood elf and high Elf units gain extra regeneration of 0.25 points
that add up to a total of 0.50
However this ability so it would work on the day shift

and I would like an equal but the night elves, which would give extra regeneration during the night shift
all night elfs have 0.25 regeneration (always)
and with this skill gain overnight an extra 0.25 to 0.50
