D&D 5E is this nova makes sense? op?

curse bringer smite from 3rd level spells.

I am sorry, I have no idea what is this. A paladin smite from 3rd level spells adds 4d8 (4*4.5) damage per attack. I haven't found anything on either the oath of conquest or the hexblade that changes this.

 

[spartanah]

UA warlock hexblade contains invocation that creates a two handed sword and you can add 2d8 per spell level instead of the paladin smite that adds only one die.
that Hexblade also has hex curse that you can add proficiency bonus to the damage.

2d6 from weapon damage and +4 from str 18, 2 attacks with 2 smites and hex curse prof bonus
+10 from GWM

so it's a total of 126 DPR with 1 round of preparation. but if I do it during the fight I can spend another round of preparation for the devills sight, oruse my spiritual weapon instead of hex. which is even better.

but I see it's not OP, so it's fine. I was just checking to make sure it's not broken for a campaign we are starting. cause I loved the flufff but didn't want to make an OP character

so I'm playing a 13th level hexblade oath of conquest fallen aasimar.
and I figured that I can nova with GWM (7+4+10+4.5*6+5)*2 +13

(Two handed+18STR+GWM+hex smite)* 2 attks +aasimar

it's 119 DPR nova. and not that complicated to achieve. and I excluded crit chances.
is it op?
I indeed used playtest material but not anything that seems op in the first place and I don't know if it's big for lvl 13.

Just as a point, it's not a 119 DPR because you haven't figured in hit chance yet. DPR has a specific meaning. The normal figure we use to hit is 65%, but at 13th with 18 instead of 20 attack stat and no bonus to magic listed for damage (there are invocations for that), I'd go 55%. Which with GWM becomes 30%.

I will add in crit chance, because that's important for triggering GWM's bonus attack.

25% hit * 53 + 5% * 71 = 16.8 expected damage per attack.
Change of any hits or crits to deliver aasimar 1/turn damage: 1-70%^2=51%. 13*51%=6.63
Chance of any crit to get extra attack: 1-95%^2=9.75%. So expected damage from GWM bonus action attack attack is 9.75% * 16.8=1.638

DPR = 16.8*2 + 6.63 + 1.638 = 41.868

I don't feel like going through all the math again, but you probably do more damage without the -5/+10 from GWM, though since a miss doesn't count for a slot for smite, fewer+harder hits like you have here might be a reasonable resource usage strategy. Skipping GWM completely for a 20 STR gives you a better chance to hit and better damage though less single-hit damage.

Also, taking some of the pact-blade-magic-weapon invocations would help both hit chance and damage, increasing your DPR no matter which way you go.

I was just legitimately curious. And I seem to have botched my search skill. Thanks for clarifying. Strange thing though that this invocation mimics a feature from another class but is more efficient.

You chose a quite conservative assumption for hit chance, based on what was already discussed. [MENTION=6802723]spartanah[/MENTION] mentioned somewhere upthread that they intend to use it in conjunction with devil sight (which seems to imply also using darkness), and also that they plan on taking an initial round of preparation to be able to activate both hexblade curse and hex. I would assume they will use darkness + hexblade curse on the first round and then hex + two attacks on the second. Also, the conquest paladin can ditch a channel divinity into a +10 attack bonus, that they can use after seeing what was rolled in the die roll to attack.

On the other hand, needing the first round just to set it up might lead to very circumstantial use of such nova in full power, and needing the bonus action to activate hex on the attacking round denies the opportunity for a bonus attack on a crit.
