Cohort 1: Sorc 6th/Dragon Disciple 1 (Combat Cohort)<br>Chr 12 only and the feats Empower and Cooperative Spell. All other feats would be Draconic/Combat feats.
Cohort 2: Sorceror 7 (Counterspelling Cohort) Has the feats Imp Init, Cooperative, Imp Counterspelling, Reactive Counterspell.
Figure on getting off 1-2 rounds of a cooperative 3nd lvl spells.
*'''DC 24 for evocation spells''' (DC 21 base; +2 for first pair and +1 for third caster)
Followers would be human fighters with cooperative fighting feats. (Swarmfighting? Haven't looked them up yet.)
Note that if I was an evil DM I could, by the rules, call this NPC a CR 9 encounter. :)
