+// TMW-2 Script.
+// Author:

+// Description:
+//    Applies effects for INC_* (STR doesn't exist)
+//    Valid values: INCAGI INCVIT INCINT INCDEX INCLUK INCHIT INCFLEE SC_FURY
+//    Doesn't works: SC_STRUP
+//    Works if .@min == .@max: INCMHP INCMHPRATE INCMSP INCMSPRATE
+///   Untested Values: WALKSPEED (reverse logic) INVINCIBLE (broken)
+//    PS. SC_FURY causes crit rate to increase
+//
+// Variables:
+//    .@delay    Second of buffing
+//    .@type     SC_*
+//    .@min      Min amount of type
+//    .@max      Max amount of type (optional)
