well sorry i missunderstood what u said .about level well u might get lvl 30 in first day if u geek and will slowly decrease , skunk knows this best , but like on a lvl u will require 1k exp at the other 1.3k exp , nothing too huge leaving level gaps .as for sin ,yes they will have some official spells like MpEater , Moonlight ( sneak which grants u 3x damage 1 hit before it takes u out ) , DarkBody ( sort of moonlight but makes a clone of yours which hits the target and after a while BOOM , but u ain't getting 3x damage , its more like of an escape or diversion spell.Ambush ( tele u near the target , having a small chance to para it for 2secs) sin stats will be lower than worries but will have higher dc base and he will have 8attack speed from haste while a war will hit max 3-4 attack speed( if u sacriface dc for attack speed) also it has others spells which may differ from official , but this is a short preview of the Assassin
