Energy Field

Sometimes the caster needs to stop an enemy from advancing any further, and if no attack spells are available, this spell comes in handy. It will create a solid energy field that none can pass, not even the caster. Beside waiting for it to dissolve, which can take a long time, the only other way to get past it is the Dispel Field spell, which will destroy the field.

Note that Energy Field was originally an umbrella term for all the types of magical fields: Poison Field, Fire Field, Sleep Field and Lightning Field, and the same spell would be used to create any of them. Later (after Ultima IV), different spells were designed for each of the fields, and the previous Lightning Field came to be known simply as Energy Field. However, at times the four spells are still called "energy field spells".
