Specialisations? OoC.

Me and Jonny's specialisations are combat magic because of the training at Durmstrang. You know, protection charms(waving wand before you and dispelling a spell, wordlessly), attacking with bolts of magic, stupefy, and other things. Eric is best at fire based magic due to the core and wood of his wand. Jonny'll have to post his own stuff.
What are your specialisations?

Addition: He has also made his own spell, psidium fulgurios, which hits the target with a bolt of lightning and, if there is only one target, hits vital organs of the target. If however, if there is more targets, it spreads from the original target to all the enemies at the same time.

OOC: more than combat Jonny is speciallysiced on patronus charms and his patronus charm is a lion. In combat it is attacking with fire, cutting, lightning and water, most of combat. He is not so good with healing charms and such stuff. And he has made his own attacking curse "DEMEMBRARIO" who dismembers people.
SUFFOCATIO AGUA- an choking curse were the victim gets choked by water.
CHORUMNO FLAMMIATUS- a flame that flies in the air in thin threads and goes for
the eyes of the victim
PROTEGAMOS CONTERAIMIS- Shatters defence spells.
EXTINGUERO FLAMMIO- extings all flames nearby (spells)

Apollo doesn't really have much of a specialisation (though he leans towards coldness), but he has a few spells of his own creation:

Fulgoradius: a cursed bolt of lightening.
Flammelicus: an unnatural, moonlight-coloured fire which syphons all the warmth from the room.
Crura perfringo: a leg-breaking curse which shatters all the bones in the leg.
Crura perfracta Coeo: the counter-curse to the above.
Frangentimore torto: a curse designed more to attack the soul than the body.
Algorunda: a blizzard wind blows at the target, encasing them in cursed ice.

OOC: Aimees is the darks arts and she's very skilled in it for someone of her age. She's also commited 3 muggle murders and 1 witch murder.

Solei's specialised in, of course, fire magic. He's a fire elemental so he can generate heat waves, fire balls out of thin air, and much more. You can find it all here: harrypotterfanon(dot)wikia(dot)com(slash)wiki(slash)Elementals If you look away from the fire magic, he's somewhat skilled in protective charms, but he does know other spells as well.
