Re: Leadership Formulas
 

Leadership values for magic are as follows:
Undead: 20 per death loevel, 10 per unholy priest level, 5 per blood, none for anything else.

Normal: 5 per fire magic level

Magic: 5 for each level of fire, air, earth, water, nature and blood magic, 10 per astral magic level and nothing for death and unholy priest levels.

Crown of command increases normal leadershp by 50 and magic leadership by 25. Whip of command and Scepter of Authority also increase normal leadership. Having all three on the same commander gives that commander awe(+0). Substituting O'al K'an's Sceptre for the authority sceptre boosts the awe to awe(+1) and gives better leadership.

Rod of the Leper King and some other items boost undead leadeship.

If a unit is both magic being and undead (such as mandragoras and manikins), the capability to lead them is determined by undead leadership and magic leadership requirement is discarded. So a bane lord with no magic can lead them but a master smith of Ulm could not.

Wraith Crown gives substantial undead leadership increase (+50 even if they had none), and the ... soul contract gives +10, even to something like a black servant that normally has zero.

D'oh! I've only been counting 10/death.

As often as I've looked at that table in the manual, I can't believe I made such a dumb mistake. Thanks for the correction.

BTW, the only reason I didn't say it was affecting "all" my Thaumaturges is that I've only seen this happen when assigning troops by double-clicking them; when I'm shift-clicking them, I only select as many as I thought the commander could take.
