[Dynamic Thrust]

{ bonus bInt,2; bonusautoscript "{ sc_start SC_FASTCAST,5000,50; sc_start SC_INCFLEE,5000,30; }",10,BF_MAGIC; },{},{}

See this 50? That's the 50% faster cast part. Both statuses have a 5000 near them, and since Ragnarok only measures durations in seconds, I'm assuming that's 5000 seconds.
