Spell Description

You weave arcane sigils of instruction, binding a core animus into a chosen material to form a Thrall, a medium sized guardian/assistant golem designed by the famed professor Wranzumin Candor. The Thrall obeys your verbal commands, acts on your initiative, and does nothing without your direction. If given no command, it takes the Dodge action.
