Other Portal
An other portal is a manufactured structure that teleports the player 500 blocks up in the Overworld. The portal can only be ignited in 23w13a_or_b.
An other portal is built as a vertical, rectangular frame of glowstone (4×5 minimum, 23×23 maximum), similar to a Nether portal. The four corners of the frame are not required. Adjacent portals can share glowstone blocks. An other portal cannot be built horizontally like an End portal.
Once a frame is constructed, it is activated by water placed inside the frame. This creates portal blocks inside the frame, resembling a vortex. The water can be placed in any manner, including use of water bucket, dispensed by dispenser or natural spread of water. Other portals can be activated only in the Overworld; they cannot be activated in the End and custom dimensions.
