Spend a spark and a few spell points to swap your entity for another one you control. This replaces having to banish your current entity and then summon another. This is a handy spell to deal with an occasional nuisance, I have no idea why it’s one of the most expensive in the guild to study.
The in game help reads:
No saving throw. Casting time: 4 rounds. Type of spell: neutral spell. Affecting stats: int/wis. Cast type: rift. Spell point cost: 18. Once a riftwalker has control over a number of different entities, he/she can transform their existing entity into another entity type. NOTE: solo kills will NOT register on the top kills plaques for 30 minutes after using this spell. Syntax: cast transform rift entity at <type/name> This spell uses 1 rift spark.
