comobo is not recomanded @ the early stage, but as a trans high dmg atk, you can take both to LV up or just take one due to not enough SP, and soul spear and ghost spear are the most important ones. BUT! later when u get to lv 60-80, you better need the combo to do both PVP and LVup, as i tested in chinese server lv 70+, combo is very useful, and besides, when u max soul and ghost spear and fly dragon, combo must be your next choice:) like i said, it MAX the dmg of Glavie, so....lean it for sure, decide when by urself(when you have enough SP)
