I personally feel bad when using a 8 or 9 research pan to summon a carrion. I feel I'm wasting my time. But you may not have access to another death caster, so...

I will be more specific on the reason why summoning centaur is a waste of time for me.

1 in death magic lets you recruit the mound king. It requires enchantments 2 which is needed for other carrion spells and summons, and also for the more powerful enchantment spells (gift of health, or the foul vapor spells that makes a nice combo with manikins since they are immune to poison). The mound kind is in my opinion vastly superior because :
- one in priest level is not that powerful.
- both have immunities to poison.
- 40/80 standard leadership compared to 10/80/10 let him move maenads (or other troops) around,
- is still immune to poison,
- move 4/25 instead of 3/20 (but no forest walking),
- costs 3 death gems instead of 10 nature gems you could do something else with (like summoning a lady) !

The centaur reanimates 1 carrion per tur, the lady 2, and the king 3 (for 10 / 16 / 25 gems respectively). There is, once again, no point in using the centaur to reanimate them.
