Im Currently using a Helenid+8. My AP with is 2203 with the Weapon Enchant.
Im also planning on getting 4 pieces of Full Plate +9 and have Shell Pauldron+8.
HP w/ undy : 6200
AC w/ 350 : 1159
Do I make the switch to the IB+9 because of the extra AP or stay with the Helenid+8 for the glacier and weapon enchant?
