Special Traits

• Acidic Secretions. A creature who touches the t’shann takes 5 (2d4) acid damage. Any nonmagical weapon made of metal or wood that hits the t’shann corrodes. After dealing damage, the weapon takes a permanent and cumulative -1 penalty to damage rolls. If its penalty drops to -5, the weapon is destroyed. Nonmagical ammunition made of metal or wood that hits the t’shann is destroyed after dealing damage. In addition, nonmagical armor worn by the target of any of the t’shann’s attacks is partly dissolved and takes a permanent and cumulative -1 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10.
• Alien Thoughts. When a creature enters or starts its turn within 30 feet of the t’shann, the creature must make a DC 13 Wisdom saving throw, unless the t’shann is incapacitated. On a failed saving throw, the creature can’t take reactions until the start of its next turn and rolls a d8 to determine what it does during that turn. On a 1-4, the creature does nothing. On a 5 or 6, the creature takes no action but uses all its movement to move in a random direction. On a 7 or 8, the creature makes one melee attack against a random creature, or it does nothing if no creature is within reach.

About

The slug-like thing has a cylindrical body and a mass of dripping, writhing tentacles at its head. It is brownish gray, with patches of green and black blotches scattered unevenly over its body. Its underside is pasty off-white in color and ripples with the muscular contractions that move the creature along.

T’shanns are slug-like creatures that burrow through earth and stone to consume the minerals trapped in the rock. They range anywhere from 2 to 4 feet long. A t’shann burrows through stone by extruding powerful digestive enzymes through its mouth and skin, that let it dissolve the stone, and then slurping it up for consumption. It can use this ability to attack creatures that threaten it.

The most unusual aspect of a t’shann is its ability to cause confusion by its mere presence. The simple but alien brain of a t’shann emits waves in such a frequency that more advanced creatures suffer from severe disorientation if they come too close. T’shanns rarely attack. They are content to burrow through rock and dirt, blissfully unaware of the rest of the world. If attacked, however, a t’shann defends itself with all the natural weapons available to it.
