Theodore Tries To Help Theodore, you're right. A 3-target Hold has no modifier to the save. But as it says below, what was cast was four 2-target Holds, which each have -1 to the save. Actually, tiling the party with three saves with no penalty probably would have the greatest chance of success, but oh well, that's not what happened.

Thaka, you now somehow have a flaming sword. Please don't forget your save vs. blindness. Theodore then shoots a priest in the side.  ¶ 3:13 PM
