As mention in info, Emizel can cast magic. Pretty much your typical RPG kind. Canonly there is only really three kinds of it (Four if you count star, but that's a little more complicated), which all are just damage dealing. However in a more realistic setting, each kind of element instead serves a different role for him. Giving them plenty of other uses besides covering enemy weaknesses. In other words, Emi plays like a Warcraft mage, deal with it.
Fire: The only one that doesn't change at all from it's initial in-game use, which is burning the heck out of everything. Fire is the element Emizel uses most since it tends to be the most destructive and gets the job done in real fights. Styles of it seem to range from fireballs to combustions.
Ice: Creates chunks of well, ice. It can still be use offensively too by getting it to slam into opponents, but it works best for making shields and barriers. Freezing other people can sometimes work too but can be harder to pull off. It's simply good at just buying time though, or in some situations, create platforms.
Wind: Probably the most useless of the three however it interestingly ties itself well with both of them. Wind can somewhat complement fire and ice, making them a bit more useful in other ways. Wind can also play with it's surroundings like dirt/sand, water, and other potentially helpful things. It can't really hurt anything on its own, and it can't really block anything either, so instead it relies on doing other tricks.
Now that we got generic magic out of the way, time for the things that actually make Emizel a bit more unique. (And relate to his ability as Death)

Soul Reaper: Not... really a skill XD. More like a proof of how much failure he is. And why Emi can't ever reap anything that's not inanimate.
Grim Specter: The strangest of the specials. The mask itself may make appearances once in awhile (if it ever does come up), but other than that, will unlikely ever happen.
Delta of Death: Emizel's transformation. He's a lot of competent in that form and way more stronger, but simply for balancing reasons, can only use for a certain amount of time. Best saved for boss battles or other epic fights, unless something flipped him into berserk mode.
