Level 17: Seadeeps Seadeeps is designed for four 14th-level characters, and adventurers who defeat the monsters on this level should gain enough XP to advance to 15th level. Before running this
level, consider reviewing the “Gith” and “Mind Flayer” entries in the Monster Manual, as well as the “Ulitharid” entry in appendix A. They will help you roleplay the monsters on this level and bring their conflict in Seadeeps to life.

15. Standing Gate to Level 17 Rising out of a 2-foot-deep pool of ooze is a pair of 15-foot-tall standing stones topped with a lintel, carved into which is a symbol of an arrow. The standing stones
pass through this gate (see “Jhesiyra Kestellharp”). The first creature to pass through the gate triggers an elder rune (see “Elder Runes”). A creature that passes through the gate appears in area 8b on level 17, in the closest unoccupied space next to the identical gate located there.
