an idea I got about 1st level DPR; Curse of Io's Blood is probably the most damage you get for a feat
this assumes both I can be bloodied and that I can curse my target. if any of this can't be met, damage drops accordingly
Dragonborn Warlock 1
Str 20
Curse of Io's Blood
Maul MBA
Attack: +8 vs AC
Hit: 2d6 + 5 + 1d6 + 1 + 5
breakdown
5 (Str) + 2 (prof) + 1 (Dragonborn Fury)
DPR: (0.65*21.5)+(0.05*29)=15.425
DPR (Ch): (0.7*21.5)+(0.05*29)=16.5 (Ch)
previous entry with Eldritch Strike
Dragonborn Warlock 1
Str 16, Cha 20
Curse of Io's Blood
Maul Eldritch Strike
Attack: +8 vs AC
Hit: 2d6 + 5 + 1d6 + 1 +3
DPR: (0.65*19.5)+(0.05*27)=14.025
a solid third
EDIT3: just remembered that Eldritch Strike is a MBA, so I can charge...
everything the same, except
Attack: +9 vs AC
DPR=(0.7*19.5)+(0.05*27)=15.0
being MBA also means we pick up Bracers of Mighty Striking and go to town @2
previous entry with Eldritch Blast
Dragonborn Warlock 1
Str 16, Cha 20
Curse of Io's Blood
Eldritch Blast
Attack: +7 vs Ref
Hit: 1d10 + 5 + 1d6 + 1 +3
DPR: (0.7*18)+(0.05*25)=13.85
previous entry with Gorebrute Charge
EDIT: I know this is supposed to be at-will, but how about encounter long buffs?
again, I need to be bloodied (Longtooth Shifting)
Longtooth Shifter Barbarian 1
Str 20
Gorebrute Charge
Maul Howling Strike
Attack: +8 vs AC
Hit: 2d6 + 1d6 + 5 + 2 + 3
DPR: (0.65*20.5)+(0.05*28)=14.725
EDIT2:
For Level 1 DPR, I'd imagine a githzerai night stalker might be the way to go.
Githzerai Assassin
Dex 20, Cha 14
Feat: Githzerai Blade Master
Shadow Storm w/ Fullblade: +8 vs. AC, 1d12 + 5 (Dex) + 2 (Cha) + 1 (Power) + 2 (Feat)
DPR is 14.73 assuming that your target is isolated, and that you invoke your shrouds every round. You shouldn't, of course, but it's 2:30 a.m. and for the purpose of this exercise it's the most straightforward way to go about it.
(.65*(16.5+3.5))+(.05*(22+6.5+6))
EDIT: DPR assuming shrouds every other round: 15.24
Every third and fourth rounds bumps it up higher, but is less likely to be useful in a game situation (15.43 and 15.51, respectively).
if you're stacking your shrouds to 4, you get more DPR from Leaping Shade, basically trading +1 to damage on every attack for +1/+2/+3/+0 rotation.
the least thinking required to calculate this is every round for itself and average (it's getting really late here
)
DPR calculations for each round
DPR1: (0.65*16.5)+(0,05*27.5) = 12.10
DPR2: (0.65*17.5)+(0.05*28.5) = 12.80
DPR3: (0.65*18.5)+(0.05*29.5) = 13.50
DPR4: (0.65*(15.5+14))+(0.05*(26.5+24))+0.3*(10.5) = 24.4
average DPR: 15.8125
that's more then 1 point over my longtooth charger, and he uses his encounter power!
now I agree it's unpractical to wait for 4 shrouds, but blocks of tofu don't mind I guess Laughing
EDIT4: I found error in my math and corrected it, optimized Githzerai Assassin DPR is now 0,05 lower
