Cling [one-action] Feat 9Goblin Source Player Core pg. 57 2.0Requirements Your last action was a successful Strike and you have a free hand
You hang onto a foe to harry them into submission. If your target moves while you're hanging onto it, you can choose to move with the target. The target is released if you choose not to move with it, at the start of your next turn, or if the target
Escapes. Attempts to Escape from a Cling are made against your Acrobatics DC and follow the rules on page 416, but they end the Cling instead of the conditions normally ended by the Escape action.
Special You can use this action without a free hand if your preceding Strike was made with your jaws or a similar unarmed attack you could use to hang on. The GM determines which unarmed attacks apply. Hanging on in this way prevents you from using that unarmed attack.
