Description: An aboleth with this feat can create magic glyphs that store spells or have specialized effects of their own.

Prerequisites: 5th Level Caster, Aboleth

The creature can create a permanent glyph of warding effect that automatically recharges and replenishes its own energy after a short period of inactivity after it is triggered. Crafting an aboleth glyph takes one day for each 1,000 gp in its base price. The base price of an aboleth glyph is its caster level times spell level times 1,000 gp. To create the glyph, the creature must spend 1/25 of the base price in XP and use up raw materials costing one-half of the base price. A newly created glyph functions exactly as if the creature had cast glyph of warding on the affected area, except that the glyph automatically reappears 1 minute after it is discharged. Similarly, if the glyph is dispelled, it reforms as good as new 1 minute later. An aboleth glyph can be destroyed only in the same manner that a magic item can be destroyed--Mordenkainen's disjunction, physical destruction of the glyph, and so on. Alternatively, the aboleth can create a master glyph. Each master glyph is a unique glyph with specific effects and base costs.
