Here's what I did:
As an Aco:
lv 10 Heal
lv 5 Divine Blessing
lv 10 Blessing
lv 10 Agi
lv 1 Ruwach
lv 2 Teleport
lv 4 Warp
lv 1 Pneuma
lv 1 Aqua Benedicto
(You will have three or four left over job skills, I just put them in Angelicus for extra defense).
As a Priest:
lv 4 SP Recovery
lv 1 Status Recovery
lv 3 Imposito Manus
lv 4 Aspersio
lv 3 Sanctuary
lv 1 Safety Wall
lv 5 Lex Divinia
lv 1 Lex Aeterna
lv 3 Turn Undead
lv 3 Magnificat
lv 10 Magnus Exorcismus
(you will have some more left over job skills, I put the rest in Sanct since I have IC. If you don't have IC gears then I suggest putting the rest in SW instead).
