Hello, everyone!
I play on C4 and I´m Dark Wizard lvl 37. But still, I can´t find any informations about PS and SH. Could you tell me the pro´s and con´s of both? PvP? PvM? CS? thanks a lot

well those are two different classes.
PS(Phantom Summoner) is a summoner and bases its damage on his shadow/sillhouete/soulless/nightshade with physical damage and they are great for solo-ing pve.also great for olympiad due to very powerful summon buffs.another + for him is that he doesn't really need too much equipment.a BW light set and a Homunukulus+acumen or some Health SA weapon is more than enough for pve.
bad part : not that great on fullbuff/mass pvp and nobody will invite you for RBP unless they're clan members.
SH(Spell Howler) is a nuker and its damage is based on elemental magic (wind and dark).the SH has great damage per spell and,like the necromancer,it has the Body to Mind spell which allows him to exchange hp for mp.another good part about it is that you can go to raidboss parties with it and is great for mass fullbuffed pvp.however,on oly-style,he gets pounded on really badly by other classes (gladiator,summoners,daggers,archers).

and there's more..

SH +
dmg Dmg DMG !
SH -
mana, speed
