Grapple rules. Everyone loves them right? Sure you do… well; at least we have some sort of handle on them by now. Swelled with pride at our deft gaming skills, we use them in most cases without undue hassle and rampant house-ruling. After all, most of us are well educated individuals, and many of us even enjoy puzzles!
Now, let’s just throw in a Mimic or three. Just for spice. Welcome to the Sodden Hold, room D2.
Hmm… with its Adhesive and Crush abilities, we have some new elements of grappling fun. Oh lucky me.
To Quote the Monster Manual, page 186;
Adhesive (Ex): A mimic exudes a thick slime that acts as a powerful adhesive, holding fast any creatures or items that touch it. An adhesive covered mimic automatically grapples any creature it hits with a slam attack. Opponents so grappled cannot get free while the mimic is alive without removing the adhesive first.
A weapon that strikes an adhesive-coated mimic is stuck fast unless the wielder succeeds on a DC 16 Reflex save. A successful DC 16 Strength check is needed to pry it off.
Strong alcohol dissolves the adhesive, but the mimic still can grapple normally. A mimic can dissolve its adhesive at will, and the substance breaks down 5 rounds after the creature dies.
Crush (Ex): A mimic deals 1d8+4 points of damage with a successful grapple check.
Ok, that should be easy enough to play. Shouldn’t it?
Round 1
A mimic surprises the party with its cunning Mimic Shape ability, rolls an attack, hits a flat-footed PC with its first swing doing 1d8+4 damage and automatically grapples its target. I guess its second slam attack is lost because it’s now grappling. Right oh. Hmm, mimic’s don’t seem to have Improved Grab, so I guess it moves into the targets square to continue the grapple. Ok, I move 10’ and into my targets square. Let’s hope there is enough room because I happen to be a large critter. Squeezing and grappling would not be fun. Luckily, there is room.
Ok, the Crush ability. When does this happen? After a successful grapple check. Let’s see, does an automatic grapple constitute a successful grapple check? Hmm, I guess so. So I do an extra 1d8+4 crushing damage. Least, I think so...
I guess that's the end of my surprise round.
Round 2
We all roll initiative. A few PC’s beat me, and a few don’t, as is usual. The first PC to act happens to be the grappled one. I describe the sticky substance that seems to be holding him fast to this odd anamorphic creature. He looks up grapple in the PHB to determine his options. He decides to try and break free. He gets two attempts, but fails both times automatically. I explain how the sticky adhesive just seems to be far too strong to be overcome in this fashion.
The next PC decides to attack the critter grappling his friend, (note – attacking into a square with two people grappling each other always seemed a dangerous option to me, even with melee weapons. Hence, I have a house rule that a grappled ally provides some cover to the target. Using proportional cover, a medium sized grappled ally provides +2 cover to the large critter. Obviously, if the PC hits the cover, he may hurt his ally) risking the 10% chance he strikes the wrong target. He easily hits the mimic but his weapon becomes stuck. Oops. He want’s to pull it free. Hmm, doesn’t say if the required Strength check is a standard action or not. Going easy on him I rule it’s a move action. He tries, but fails the check (Another odd thing here. If the PC want’s to keep a hold of his weapon so he can pull it free next round, is he drawn into the grapple? If two combatants are rolling around in a grapple and your weapon is stuck fast to one of them, I don’t see how you could avoid it. But it would be a bit harsh to rule this way I think… so I’ll just ignore the implausibility of it all for the moment).
Ok, now the mimics turn. It’s in a grapple and only has a BAB of +5, so – despite two normally available slam attacks – it just gets one grapple attempt at +13. It succeeds, doing crush damage again of 1d8+4. I guess that’s all it can do from now on, unless it elects to dissolve its own adhesive and just fight normally?
--------------
So, all in all, I think the players and I will find this a tricky little encounter to play.
My question to you is (with obvious house rule exceptions), am I basically playing this correctly? Is my use of grappling rules interacting with the mimic abilities correctly?
