I'm using the multi class for the first time. I have a mage/thief and a fighter/mage in my party of 6. These are the only two that are multi classed. I gave both an intelligence of 18 and used the charisma and wisdom to buff up the the fighting attributes. The problem is that both characters are not able to use their spells. They are both up to level 4. I checked the spell book and the spells are memorized. Any ideas about what I'm doing wrong? I installed only icewind dale and not any expansions. The single class cleric is memorizing his spells perfectly. Any help would be appreciated.
