I am playing a cleric/wizard/Mystic Theurge. I choose the familiar class feature for my wizard. MT only progresses a wizards spell casting and caster level. You do not learn new spells and the familiar does not gain increased abilities according to the familiar chart.
Is there a way to improve the familiar according to the chart without taking levels in a class that grant a familiar? I mostly want the ability to speak with it at level 5, and the all important spell resistant at 11th (which gets better the higher level I am).
The Iron Will/Familiar Bond/Improved Familiar Bond is not the route I wish to go because it requires way too many feats and Im already feat starved.
I know of Boon Companion, but that increases the total by 4, which helps (more so once I can get SR).
