I tend to believe that the best challenges are the ones where the PCs best toys don't always work right and they have to improvise.
I believe that the best challenges for PCs are ones
that push them outside their comfort zone. But these challenges work for one reason and one reason alone. They are
rare. The Beholder anti-magic ray rocks - it's an interesting and rare twist. The undead and construct immunity to sneak attack is obnoxious as hell because it makes one of the rogue's main abilities useless for most of the adventure. On the other hand the solution should never be "Bob can attack it; he has a +3 sword." This just means Bob is doing what Bob does.
And I think 4e got the immunities almost right. Making them mostly very rare - and far more interesting than immunities are consequences. For instance a Volcanic Dragon is not immune to fire - but hit it with fire and it produces even more thick black sulphurous fumes (I normally reskin it away from a dragon). And you can push, slide, or knock over an earthquake dragon (much better monster than an earth elemental so I use them as such). But knock over an earthquake dragon and the ground shakes, knocking over everyone standing too close. Far more interesting than a simple "It doesn't work".
Here is my problem with many of the "martial dailies" concepts.
Fighter Bob has an ability, We'll call it Sweeping Blow. Basically, the fighter can attack in a burst multiple foes 1/encounter. (F3 btw).
So once per encounter, a fighter can hit everyone around him. Why? What does he do to strike everyone around him? How does it work? Where did he learn to do this?
Same way Fighter Mack learned to Whirlwind Attack, attacking everyone around
him. Are you going to argue against feats as well?
Why can he only do it once per encounter?
Because that's a much more realistic approximation than "He can do it every single time". It's not a perfect approximation, but what you do in combat is limited by the opportunities you can see (the Orient phase of the
OODA loop). If you spend time woolgathering rather than simply using the opportunities you can see you take a sword in the gut.
Yes, there are better approximations you can come up with than AEDU. Giving each encounter power an activation number at the start of every turn (roll 1d6 per encounter power and you can use it on an roll of N+) the way 4e monsters do. The 3.5 Crusader recharge mechanic. But it's still massively better than "You can do all things all the time". But the principle that you only have the opportunity to use your more complex moves and stunts infrequently is a sound one - and at the level of detail D&D provides, this recharge cycle has to be arbitrary.
Why can't he make the same sweeping attack again? What happens if he tries to do it again?
If he tries it when the enemies haven't lined up properly it's effectively going to be a basic attack.
Why do his foes "wise up" to THAT trick but can be Tide of Ironed all around the room if the fighter chooses?
Because bullying someone backwards with your shield is a hell of a lot simpler than seeing an opportunity involving half a dozen enemies lining up just so.
What happens if his other fighter buddy wants to try it too?
What if Mack's fighter buddy Rachel wants to try a whirlwind attack? Same situation. Several solutions.
- Se can practice until it's instinctive and something she sees rather than needs to think about. Thus retraining to get Sweeping Strike (or spending however many feats it is for Whirlwind Attack).
- She can try to force it in the middle of combat - either being a second too slow or not having much chance to get the alignment properly. Either way she should be taking monstrous penalties.
- She can realise that 2 is a bad idea of the sort that gets you stabbed and concentrate on perfecting her own technique and seeing the opportunities she's best at.
This isn't rocket science.
If Sweeping Strike is a twist of luck, than theoretically it can be done anytime the circumstances are right. If its training, then the fighter should be able to replicate it (since he can Tide of Iron or Spinning Sweep all day if he wants).
You are talking as if it's an either/or proposition. It isn't. It's a combination of a stroke of luck
and the focussed training to take advantage of that luck in the split second you have to make a decision. To quote Louis Pasteur "Chance favours the prepared mind."
There is no reason a fighter should be able to pull off such a tactic once, even if the circumstances round to round didn't change (all foes still standing in their original place relevant to the fighter, it makes sense he could Sweeping Blow again the next round.
If all foes are standing in exactly their original place relevant to the fighter I want to know whether the fighter is fighting a row of statues or golems. You're telling me they either did not move an inch after a sweeping blow or stepped back to exactly where they were. The 3.X and 4e battlegrid represents
five foot squares. Every monster facing our fighter could have moved three feet and there would be no change on the battlegrid.
Which means there's no reason to think that the situation will be exactly the same from round to round even if no one has moved out of their square - and given how chaotic melees are generally there's every reason to think it won't be.
Which brings me to my issue with metaplot cards being PC only. Dominate Spells don't just work on NPCs. Vorpral swords work just as well on fighters as they do on dragons. PCs have no immunity to these effects, why should they against a fighter's CAGI power?
They don't. Forced movement works on PCs just as it does on NPCs. CAGI is just a selective effect that only attacks enemies - if the fighter were to turn on the party he could CAGI them happily. Same way that Rain of Blood from the Invoker is divine magic that burns the Invoker's enemies and empowers their allies. If the Invoker switched sides it would stop burning monsters and start burning PCs.
Next question?
Let me set up a scenario: An adventuring group (a fighter, rogue, cleric, wizard, and ranger) are wandering a dungeon and find an evil altar. The fighter, a brave dumbass, touches the altar and the DM tells him (via secret note) he is now a CE worshipper of Vecna and at the first opportunity, he must kill his allies. He's still a player at this moment, and he's not dominated (he has full control of his abilities) so the first thing he does is stand 10ft behind his friends and activates CAGI. What happens?
It works on the PCs, RAW. This is in the text of the power. Next question?
