Scroll of Titan Summoning

When you take a Magic action to read this scroll, a particular titan named in the scroll appears in an unoccupied space on the ground or in water that you can see within 1 mile of yourself. The DM picks a suitable titan or determines it randomly by rolling on the following table (see the Monster Manual for the creature's stat block).
The titan is Hostile toward all other creatures and disappears when it drops to 0 Hit Points. If the titan is summoned into a space that isn't large enough to contain it, the summoning fails, and the scroll is wasted.
