Evil

At 1st level, you can touch one ally and grant him an evil blessing. For 1 minute, this ally deals an additional 1d6 points of damage against good creatures. During this time, his attacks are treated as evil for the purposes of overcoming damage reduction. At 10th level, you can summon a battle companion. This ability functions as summon monster IV with a duration of 1 minute, but only allows to summon demons. This ability can summon only one creature, regardless of the list used. For every 2 levels beyond 10th, the level of the summon monster spell increases by 1 (to a maximum of summon monster IX at 20th level).
