Here is another bit of Pathfinder zaniness.
Introducing Wilhelm's Grappling Tentacle.
Imagine an alchemist character with a tentacle who has two levels of Order of the Penitent cavalier.
He has the feats Potion Glutton and Greater Grapple.
Wilhelm's example is level nine and has a +20 Combat Maneuver Bonus.
Each combat turn it can use Potion Glutton to drink a potion of true strike as a swift action, use the tentacle to make an sure-to-succeed attack with the grab ability, watch the high Combat Maneuver Bonus succeed at grappling the foe, and then use Greater Grapple to tie up the foe with a second grapple die roll.
Tie up any monster in one turn!
