Description of Fingolfin's Challenge
In the English version, the description of the song realm spell, Fingolfin's Challenge, mentions that it expends a few turns when it lapses. The Japanese description does not mention that, and I didn't see in the code where that effect is enforced, unlike the other globe of invulnerability spells. The attached patch removes the sentence about the turns and makes slight changes to the wording in the other sentence to make it more idiomatic.
