- If Call of Valor is used while a conjured creature is still active, the shout will dispel the creature and replace it with the summoned hero. The reverse can happen as well; if a summoned hero is active, a Conjure spell will dispel the hero and replace it with the conjured creature.
- The heroes summoned by Call of Valor can be healed by restoration spells such as Healing Hands and will allow one to keep the summoned hero indefinitely, unless another creature is summoned. This also works with Summon Spectral Assassin with the ghost of Lucien Lachance
- Like Conjure spells, the shout may be absorbed by any active Spell Absorption effects. If the shout is absorbed, a hero will not be summoned, but the shout's cooldown will still be triggered.
