How does the relic Channeler's Powerful Bond ability interact with the Sulesh the Great Legendary Spirit?
Powerful Bond (Su): Because of habitually channeling the same spirits and possessing physical links to the spirits' former lives and legends, a relic channeler possesses a strong bond with her spirits. She receives the benefit of the Alertness feat whenever she is suffering a spirit's influence penalty. She chooses two spells of each level with the archmage arcana and divine surge spirit powers instead of one, two exotic weapon proficiencies with champion's prowess instead of one, three combat feats with legendary champion instead of two, and three skills with trickster's edge instead of two.
This ability alters spirit.
Sulesh's Spells (Lesser, Su): Sulesh always grants summon monster I–VI, plus the cantrip detect magic. This ability alters archmage arcana.
Would Sulesh's Spells supersede the Relic Channeler's Powerful Bond, thus granting only the spells indicated, or would the Medium also gain a second set of (fixed) spells alongside them?
