I’m back!
You know, oddly enough, I can actually access that link! Sometimes I can link to the WotC site from work, and sometimes I can’t… this time I could! (this does give a possible explanation why thom99 thought the whipsting should be a plant, if he was thinking of the spine springer at the time.

)
Let me see, how well does it work like this:
Spring Slam (Ex): A whipsting that leaps at least 10 feet to attack a foe from a coiled position can make a charge attack and attack with both of its stingers. The whipsting gains a +4 circumstance bonus to its attack roll, making its attack bonus +X (which includes +X for the stinger and +2 for charging).
Not sure if I want to keep the pounce though…
Let me repost the other SA’s we’ve written up so far, to better keep track of things and see how it looks as a whole. Also, I wrote the combat text:
A whipsting will usually wait for prey to approach while in a coiled position; it curls one tentacle underneath itself to form a sort of natural spring. It leaps far in this position by suddenly straightening itself out to propel itself in a wild spring. In this way, it surprises its foes and lands on it, making the loud, lashing whip crack for which it is known as it drives its envenomed stinger into its opponent. It then attaches to its prey, which it continues to slap with its tentacles to drive him its stings while it tries to constrict, smother, or strangle the prey.
A whipsting facing a large or powerful foe will avoid attacking, and if necessary seeks to flee altogether by springing away. It can use its curled tentacle to leap about like a pogo stick, in a constant pattern of bobbing and bouncing.
Attach (Ex): If a whipsting hits with a tentacle attack, it latches onto the opponent’s body and drives its stinger deep into the opponent. This deals 1 point of damage per tentacle, and injects the whipsting’s venom into the opponent. A whipsting may continue to make tentacle attacks each round that it remains attached. An attached whipsting is effectively grappling its prey. The whipsting loses its Dexterity bonus to AC and has an AC of X, but holds on with great tenacity. Whipstings have a +X racial bonus on grapple checks (already figured into the Base Attack/Grapple entry above).
An attached whipsting can be struck with a weapon or grappled itself. To remove an attached whipsting through grappling, the opponent must achieve a pin against the whipsting.
Venom (Ex): A whipsting’s stinger injects the creature’s venom into its prey. This venom is also effective through skin contact. For every successful attack with the stinger, a victim must succeed on a DC X Fortitude save or take 1d2 points of Strength damage and 1d3 points of Dexterity damage, and be stunned for 1 round. The save DC is Constitution-based and includes a +(2?) racial bonus. A whipsting is immune to the effects of all whipsting venom, as are any creatures that are immune to poison.
- I lowered the venom damage a bit, since it is effective on every hit. Also, the effect is better described by “stunned” than “nauseated” – and stunned is more severe than nauseated and covers everything that nausea covers, so I changed that as well.
For the whipsting’s feat, I’m starting to agree with Krishnath on just Weapon Finesse. I was originally considering Improved Grapple, but we can give it a big enough racial bonus for Attach that that feat won’t be necessary at all. I was also considering Multiattack, but that might also be unnecessary. With Weapon Finesse, it would be +6 to hit with bite, and +1 to hit with stingers. The spring jump attack bumps that up to +7 though, which it would use at every available opportunity.
“If facing a large foe, a whipsting often avoids attacking or seeks to flee altogether by using this curled tentacle to leap about in a constant bobbing or bouncing pattern, like a pogo stick.”
Should we make use of this somehow? AC dodge bonus? Add it to the spring action above?
A whipsting eats any meat it, can, living or dead, gorging itself tirelessly. Its elastic body can expand to contain meals of up to 10 times its own size.
don’t remember if I asked this before or not, but would this be a useful ability in any way or should we limit that to flavor text?
