Okay, I've been away. For the past several weeks, things have been rather hectic, then there was my long-awaited holiday when I was either rushing around like crazy, or not well, or away relaxing. And then this week has been hugely tiring. So I've basically been beaten down by life, and just not had time to blog.
Basically, I've been away regenerating. Which is somewhat appropriate, given that I've been sitting on a rant about that very subject.
A couple of sessions ago, our heroes ran into a band of trolls (actually, half-dragon trolls, but that's not hugely relevant right now). Of course, the iconic feature of trolls in 3e is their ability to regenerate damage.
The way regeneration in 3e works is like this: any damage the creature takes, unless caused by the creature's specific weakness, is converted from lethal to non-lethal damage. This means that instead of counting down to 0 hit points, you instead count up. When the damage taken reaches the creature's hit points, becomes staggered, and if the damage taken exceeds the hit points, it becomes unconscious. However, the creature also regenerates a number of hit points per round, even once rendered unconscious.
On the night in question, the PC wizard wasn't present, and so suddenly they lost their most potent source of fire damage (acid normally works against trolls, too, but not these half-dragons... but who carries lots of acid around?).
The consequence of all of this was that the PCs would keep hitting the trolls, eventually dropping them into unconsciousness. Then the trolls would regenerate and get back up, then get knocked back down again, and so it went on. The combat turned into a really, really tedious grind-fest of bouncing trolls. (And it could have been worse - see below.)
The fundamental problem at the core of this is that 3e doesn't provide any means for characters to convert non-lethal damage into lethal damage. That being the case, without the use of fire or acid, it is all-but-impossible to kill trolls. Basically, you have to strangle them to death. Yes, seriously.
Strictly speaking, even once the trolls had been knocked into unconsciousness, you can't apply a coup de grace attack to behead them and thus finish them off - by the book, in order to do this you need to apply real damage (so, fire), and the saving throw is based on the real damage done (so, lots of fire). Fortunately (though it was a close-run thing), I had the wit to ignore that particular issue. Otherwise, we might still be resolving that combat.
The upside of this is that I've now realised (and seen graphically) just how much of a problem regeneration is in the game, especially if you don't have exactly the right attack mode available to deal with the problem. And so, I have a two-part solution...
- Firstly, I'm inclined to steal something from 4e. In 4e, regeneration works like this: on its turn, a creature with regeneration heals all damage taken that round. However, if it is successfully attacked by it's "specific weakness", the creature's regeneration is turned off for a round. That being the case, a troll could be attacked with a burning torch and then hacked to pieces. I think that's probably right. (That said, I'm not so keen on the "heals all damage" bit - I think I'd be inclined to increase the rate significantly, but not make the healing unlimited.)
- Secondly, I think that in the case of regenerating creatures, if the creature takes 10 more damage than it's hit point total, it is rendered inert. In this condition, it remains alive, but it's regeneration is vastly reduced. It will take a significant length of time (that is, weeks) before it regenerates back to having 'only' "hit points plus 10" damage, and so be able to regenerate properly. (To go along with this, I would remove the ability to apply a coup de grace to a troll without first disabling its regeneration. Which seems fair enough - you don't really need both.)
The net result of these two would almost certainly have been that the start of that combat would have been quite a bit more nasty. However, once the PCs realised how to knock the trolls down so that they stayed down, the combat would probably have closed down quite quickly - instead of having the trolls constantly bouncing up and down (and the frustrated Ranger not quite getting to apply his coup de grace), they would have been dispatched quite handily. And I think that's about right.
(Incidentally, 3e has a related ability, fast healing, that some creatures enjoy. Those creatures simply heal a number of hit points per round. However, because they are taking normal damage all the way through, this ability doesn't have quite the same problems as regeneration. As was demonstrated at this week's game.)
