Rules combinations or realisations that "break" the system.

I just realised something awesome about rogue thieves. At 17th-level a rogue thief could do 20d6 damage... multiplied by two.

 

Of course, they'd have to crit on two attacks for that but still, that's pretty broken, lol. By 17th-level you'll no doubt have access to feats or magic items that increase threat range. Heck, if you add in 3 levels of fighter that's 19-20 crit range alone.

 

For clarification purposes, that's the 17th-level thief ability Thief's Reflexes plus Sneak Attack, using a shortsword and doubled on a crit.

 

Now I'm going to go to bed dreaming of a rogue that can do 40d6 damage on the first round of combat... and the accompanying nightmare of having to roll 40 six-sided dice :D

Not seeing the issue.

 

Wizard can hit for 40d6 in a massive area 1/day.

 

Fighters, with a maul and action surge can hit with 16d6 + 40 (roughly 27d6), twice per short rest.  

Before crits.

 

Rogues can get a free crit at level 20, but they are still behind on the damage.  Even with their double turn.

Well, they beat clerics, but that's it.

 

 

And 40d6 is ~140 damage.  That won't neccicaraly kill a high level creature.  Or even a fighter.

When dice get this numerous I sometimes prefer ye old SoD mechanic.      In this case, I have no problem with the rogue dealing a death blow at level 17, I just don't see the need for all dice.

So far, I have only seen one ability that I know will cause problems. By the rules as written, overchannel used with cantrips will be very problematic... I have a feeling, however, that the intent of overchannel was that it can only be used with spells between level 1-5.

Rogues can only use sneak attack once per round, so even in the unlikely event that they get two critical hits on both attacks with TWF in the same round, they only add the sneak attack damage to one of those critical hitting attacks.  So that is 10d6 per round, if you get at least one crit, and no more than that, no matter how many crits you get that round.

I won't say it "Breaks" the system, but a party with at least two fighters that both take the protection fighting style will mean that most NPCs/monsters will constantly attack with disadvantage rolls.  In case you are wondering how 300 Spartans held off all those dudes.

Oh, and my idea on protection style fighters is not as uber as I thought, since you use your one and only reaction to try to save an adjacent buddy, so the second attack vs. that buddy is not at a disadvantage (well, unless the buddy has another adjacent fighter with protection style).  Still nice though.

Actually, it works fine with cantrips, rules as written,  if cantrips are defined as 0 level.

 

The first time you overchannel a cantrip, you are good.

 

The second time you overchannel a cantrip, you take 2d12 per spell level - so again, you are fine since 2d12 * 0 = 0.

 

The THIRD time, and I quote, "the damage per spell level increases 1d12" - NOW you take 1d12 damage.

 

And it increases from there. So no errata is needed; though a clarification is probably called for.

 

 

(Semantic clarification:  I am reading "damage per spell level" as a specific game effect noun clause; or in other words "the damageperspelllevel increases 1d12" is not the same meaning as  "the damage increases by 1d12 per spell level".)

Broken things so far:

 

Rogue Fast hands - extra magic item attack, or potion, or acid flask at lower levels, every round with bonus action. Very broken with healing potions and uncanny dodge, which is already one of the best abilities in the game. 

Concentration being broken by damage - most in combat buffs are worthless for wizards, especially at higher levels when the save DC will exceed 20.

 

Neither of these things were in the open playtest.

 

OP things so far:

 

Sleep

Action surge

Uncanny Dodge

 

Unintended things which actually work better as written:

 

Overchannel cantrips (even with overchannel, evokers do a good deal less average damage than martials. At level 14 wont come up much in most campaigns anyways).
