SkillTable.getInstance().getInfo(1204,2).getEffects(st.getPlayer(),st.getPlayer())
the buffer use the effect of the skill so its not a cast the buffer give you the effect of X skill thats why it dont consume mana
if you get buffs with gm char but with player dont check for adena first how much it needs and how much you have than check for any lvl restriction if not work try another buffer too and compare them
