Undead summon and Palemaster

[Epistaxis]

A few questions and suggestions.

1. Will the mummy summoning continue to improve with palemaster up to level 30 palemaster. Is it wort going with 10 wiz/30 palemaster compared to 20 wiz/20 palemaster?

2. I recommend to change the max level for the greater undead summon to 25. The Palemaster cannot get the epic mummy summon until level 25 which means he is stuck with the level 21 undead from greater undead summon from level 21-25.
The palemaster is supposed to be the best undead summoner but other spell caster can get the mummy summon allready at level 21.

3. Can you show how the undead summon progress compared to your palemaster levels? I now have a level 20 palemaster (10 levels of wiz) but have not seen any improvement to the summon the last two levels other than extra hitdice.

4. Is it possible to change the feats selected by the summon? He picked skill focus in concentration at level 30, it is allmost as worthless as all the armor and wepons feats as well as the power attack/improved power attack which he never uses. Maybe change him from 15 undead/15 fighter to somethings else with 20+ levels in one class to allow him to pick epic feats.
