+// Structure of Database:
+// SkillID,CastingTime,AfterCastActDelay,AfterCastWalkDelay,Duration1,Duration2,Cool Down
+//== Explained:
+// CastingTime : time to cast this skill, in miliseconds
+// AfterCastActDelay : "normal" delay, character cannot use skills, in miliseconds
+// AfterCastWalkDleay : amount of time before character can move again, in miliseconds
+// Duration1 / Duration2 : usually the durations used by the skill, at special cases it is used to hold special data
+// Cool Down : amount of time until character can re-use this skill, in miliseconds
+//== Extra
+// On all fields you can use ':' as a delimiter to level-specific values,
+// - Example using SM_PROVOKE
+// - Original:6,0,0,0,30000,0,1000
+// - ModifiedTo:6,0,0,0,30000,0,1000:2500:3000:etc
+// - Makes lvl 1 have 1000 (1s) cool down, lvl 2 2500 (2.5s), lvl 3 3000, and so on.
