Legacy of the Forlorn
Intense Gouts of Sticky Goo
A tangler grenade showers all creatures in a 5 foot radius burst with an incredibly sticky compound that can render a target immobile in a few short moments. Any time a character is struck by a tangler grenade, that character suffers a cumulative -4 penalty to Dexterity. This penalty remains in place until the compound is dissolved. If the character is struck with enough tangler grenades that the penalty is equal to or greater than his Dexterity, he is immobilized and may take no actions until the compound is dissolved.
Hardened compound dissolves naturally after 8 hours. Some rare solvents may be able to remove the compound prematurely.
