I think i will keep this solution if others fail.

Some good ideas here, the problem is that with the Boots of the Plains there is no way to teleport something designed to kill him on top of him, since he'll be off wreaking havoc somewhere else by the time the battle resolves, so you really can't go hunt him down. (Yeah, those boots are one of the very best items in the game.) I think the only reliable way to actively go after him would be Mind Hunt spam with as many boosters as possible. (Provided he's not moving around astral casters to protect his pretender from this.) Half of them will fail because they resolve after your target teleported away, but (if you have enough potential casters) you can make sure some hit the mark by choosing casters near the top and near the bottom of the casing order.

Other than that you're stuck with using expendable raiding forces to take terriotory and clean up after him while deploying some of the measures suggested by the previous posters in the army(s) that you really want to keep protected from him. (The various blood counters are perfect if the pretender acts alone, but in my experience targeting of said blood spells is wonky, and often won't target the big-hp targets, so if he's supported by other troops you might want to look at the other options. MR 22 (+4 in battle presumably) is not at all unsurmountable if you have a couple of casters with penetration bonuses.)
