Playstyle: This build is very similar to other heavy armor-wearing sorc/pm toons. Use your mummy as a meat shield while you blast away with spells, or use your damage shields and rely on your crit immunity to not get yourself killed.
Pro's vs. other sorc/pm builds: Marginally higher AB (+2 compared to a 29sorc/1bard/10pm with 8 STR) build. +4 AC and +4con with divine shield/haste compared to tumble/haste/boots of hardiness, or +8AC compared to tumble/haste/boots of striding +8. More spells/day with a higher CHA. Higher saves with Dark Blessing. Higher DC for spells.
Cons vs. other sorc/pm builds: 1 fewer epic sorc feat. Less HP as levelup ability increases go to CHA. No UMD. Requires two pre-epic feats.
Pros/Cons vs. Exalted Sorcerer build (32 sorc/4 pal/4 rogue): Higher AC, crit immunity with PM levels. No UMD. Requires 2 feats.
