I've always wondered about this, regarding the elements

In Maple Story, these are considered as elements:

-Lightning
-Fire
-Poison
-Ice
-Holy

So here's my question. If there is Holy, why is there 'not' Darkness? Also, where's Wind, Earth, Water (even though it is similar to Ice), etc?

I irk at the fact that there's no Darkness-elemental skills or spells, maybe there will be some in the future for a new mage class? Because most of the MMOs I've played, or even RPGs, has Darkness as an element.

Note, just because it's called 'Darkness', doesn't mean it's referring to 'evil'-magic. You can use 'Holy' magic, theoretically, and still be an evil person (Tales of Symphonia, Remiel for an example, who is an angel that uses Holy-elemental spells, but he's working for the bad-guys. Also, Legend of Dragoon, Rose for an example. She uses Darkness spells/skills, and she's a hero).

I'd like to see Darkness-elemental spells in the future on MS, perhaps with a slight twist to it. Perhaps a spell that is similar to Gen, but with a slight % that it will automatically OHKO the targets (excluding bosses).

I got this idea from Phantasy Star Online, when using that one Darkness-skill, the monster has a % chance of being OHKO'ed instantly. But it had a very small %-chance. (Opposing skill of 'Grantz', I forgot the name)

B> Darkness-elemental spells, as well as Darkness-weak monsters.
