The weakness ability doesn't amplifiy the sunlight's strength, it only makes his body easier to damage when exposed to sunlight, with his overlord physique I doubt it would even itch. Nevertheless, it's useless to use [Sunlight Vulnerability] to recover his magic power quickly.

But that's not to say that using [Heat Absorption] is completely useless, but it's efficiency compared to absorbing magic power from the drakness is probably almost nothing.

That's because [Mana Aposrption] is specifically designed to absorb magic from the darkness, [Heat Absorption] absorbs magic power from heat, now then, how hot is sunlight on the surface? almost non-existent, so the efficiency drops by quite a lot.
