Sticky Poison Feat 8*Alchemist Source Player Core 2 pg. 66Archetype Poisoner* This version of the Sticky Poison feat is intended for use with an Archetype and has a different level for access than the
original feat.
A combination of additional viscosity and careful application keeps your weapons poisoned even when suffering significant wear and tear. If your Strike with a poisoned weapon would expend its poison without your target attempting an initial save (due to
resistance or your Strike being a critical failure, for example), attempt a DC 5
flat check. On a success, your weapon remains poisoned. If your Strike with a poisoned weapon succeeds, attempt a DC 17 flat check. On a success, your weapon remains poisoned until the end of your next turn.
Archetype Use
This feat can be used for one or more Archetypes in addition to the listed Classes. When selected this way, the feat is not considered to have its class traits.
