I don't think that's true for any current non-Dark Sun theme (I am not sure about Dark Sun themes, I'd have to go back an review them but they are the wrong thing to compare to anyway). You don't give anything up, you only gain. Two more-or-less random example:
Chevalier:
Level 5: Benefit: You gain a +2 power bonus to Diplomacy
checks and Intimidate checks.
Level 10: Benefit: You gain a +1 power bonus to saving
throws.
Order Adept:
Level 5: Benefit: You gain a +2 bonus to Arcana checks....(plus a free utility power)
Level 10: Benefit: You gain a +2 bonus to Will. Your bonus
to Arcana checks from this theme increases to +4.
None of those are in any way a bonus to damage.
That could be a way to go, but then you have to choose only that build and you lose a lot of other options as a result.
Which is fair, actually.
The wrong way to do it is simply to make unarmedness 'more damage' with implement powers. Given that's all monks do, that becomes a no-brainer.
Only if if outstrips using weapons making it the obvious optimal choice. I don't think I've done that, though I will review it further to be sure. I think, at this point, I've just made is a viable alternative.
The only aspect of weapons that affect monk powers are the enhancement stuff on the magic side (enhancement bonuses, critical damage, etc). Everything else with the exception of the defensive property cannot apply to monk powers because monks have no weapon powers.
Thusly, the problem is solved simply by having ki focuses have enhancements that are competitive with weapon enhancements. Everything else is a wash.
True, but there are many weapon powers and properties that do not affect an attack and all those still work just fine with a Ki Focus. In the alternative, you can use a weapon with all its powers and properties and also use a Ki Focus for non0-attack powers or properties.
That's a single weapon, and it can be fixed through errata of the weapon.
Two examples:
A Ki Weapon will give you +2 to Flurry damage even if using a Ki Focus for the attack.
An Elusive Action ki Focus gives +2 AC vs. OAs, even if you use a weapon as your implement. There is a useful encounter power, too.
For weapons, especially, there are many other examples of properties and/or powers you may want top use that don't affect an attack roll and thus can be used even if using a Ki Focus for the attacks.
This is why using a weapon is superior to using the unarmed strike.
I do relent this case, however the difference in power isn't so overwhelming as to be broken. This is no different than any character carrying a second magic weapon for its property even if they have no intention to attack with it.
No. Just ... no. It was clearly designed for monks before they switched from weapons to implement attacks. What, are you going to ask me to also believe that Unarmed Mastery is for multiclass/hybrid monks. That is straining credibility beyond the breaking point.
I'm not disputing that was its original purpose. Purposes change. The feat does serve a purpose for a specific kind of character. It doesn't need to serve some other purpose to address a perceived imbalance... are weaponless monks suffering from a damage deficit that makes them incapable as strikers?
The answer is no. Therefore, the fix shouldn't be 'MOAR DAMAGE RAWR.' Club-Stone Fist is the damaging build of choice. There is only one maximum damage build for each striker, other builds have to offer something else, and that trade-off is damage.
Your solution is simply to make unarmed monks rediculawsome and there's no need for it. Instead, why don't you give the unarmed monks the capacity to do -something else- that allows players who want more than DPR from their strikers to shine. That's why I suggest a build, that way a monk can choose.
So far your only solution has really been to just go 'MOAR DAMAGE HAHAHA' but I don't think that's the right way to go. You don't want to obsolete current builds that are also just fine, thematicly.
I think a simpler solution is to have a new Monastic Tradition:
Tiger Claw
Mental Precision: When you are wielding no weapons in either hand, you gain a +1 to attack rolls. You may use Dexterity instead of Strength on melee basic attacks using an unarmed strike.
Tiger Claw Flurry of Blows would deal 2+Constitution modifier damage and slow the target, or immobilize them if they are not the target of the triggering attack.
That'd be a decent way of increasing unarmed damage, but you'd take a hit on your flurry damage. But, +1 to hit is always good, and is competitive (without being the obvious forerunner) with ClubStone Fist.
It's pretty clear that the designers just made an error and left in the monk's iconic unarmed strike but then stripped it of nearly all real value when the monk's attacks got changed to be implements for the final version.
I think the redesign made it that SUperior Weapon Proficiency wasn't the obvious damage adder it would be with weapon powers. a +3 1d10 unarmed strike doesn't compete with a two-handed superior weapon, which is something decidedly unmonk-like. The current monk never needs a weapon, while making it so that if you want a weapon monk you're not gimping yourself.
I agree unarmed needs some support, but it doesn't need a myriad of damage adders to accomplish it. There's other ways.
