Form Retention
Preparing a battle-form spell in a higher slot buys a wizard extra minutes in that shape, without any of the usual perks of heightening.
You have trained your mind and body to tolerate polymorph magic for longer periods of time, so long as you prepare for the change appropriately. When preparing a polymorph spell that lasts 1 minute and grants a battle form, you can prepare the spell in a slot 2 ranks higher than normal. This doesn't grant any of the normal benefits of heightening a spell, but the spell lasts up to 10 minutes. For example, if you prepared animal form in a 4th-rank slot with Form Retention, you would cast a 2nd-rank that lasts for up to 10 minutes. If the spell can be Dismissed, that doesn't change.
