Edited:
Oops i for some reason went +10 dmg isntead of +9 for repeaters, reworked numbers.
Repeaters:
Full Mechanic tree gives: (Assuming lvl 20 rogue)
Sharpshooter - +7 dmg
Sniper - 1d6 SA
Expert Builder - +1 Crit Multi
Hipflask - +1 Dmg, + 2d6 SA
Improved Detection: +1 dmg, +1 SA
Base 10d6 SA from rogue levels
Greensteel:
1.50 [1d10] + 5 ; 19-20 x2
+9 Dmg, +15d6 Sneak Attack, +1 crit multi, x2 crit range (Feat), + Overwhelming Crit
Becomes: 16-29 + 15-90 SA ; 17-18 x3, 19-20 x4
Crits:
Using the Bolts per Minute from Forest - 196. 10% of those were x4 multi, 10% x3.
196*10%=19.6, Lets round for maths sake and say each is 20 shots
156 shots land as normal hits - (16*156) to (29*156) = a range of 2496-4524dmg
20 shots land as Crit x3 - ((16*20)*3) to ((29*20)*3) = range of 960-1740
20 shots land as Crit x4 - ((16*20)*4) to ((29*20)*4) = range of 1280-2320
For a total of: 4736 to 8584 dmg per minute
Sneak attack is unaffected by criticals, so an additional (15*196) to (90*196) = 2940 to 17640 dmg added on for grand total of 7676 to 26224 dmg per minute, or 128 to 437 dmg per second
Typing up Gbows now, will add right here.. ---v
Great Crossbow
Full Mechanic tree gives: (Assuming lvl 20 rogue)
Sharpshooter - +14 dmg, +5d6 SA
Sniper - 3d6 SA, +2(w)
Expert Builder - +2 Crit Multi
Hipflask - +2 Dmg, + 2d6 SA
Improved Detection: +1 dmg, +1 SA
Base 10d6 SA from rogue levels
Greensteel:
1.50 [2d8] + 5 ; 18-20 x2
+2(w), +17 Dmg, +21d6 Sneak Attack, +2 crit multi, x2 crit range (Feat), + Overwhelming Crit
3.5(2d8)+22 + 21d6 ; 15-18 x4, 19-20 x5
29 to 50 + 21 to 126 ; 15-18 x4, 19-20 x5
Crits:
Using the Bolts per Minute from Forest - 126. 10% of those were x5 multi, 20% x4.
126*10%=12.6, Lets round for maths sake and say each is 13 shots
87 shots land as normal hits - (29*87) to (50*87) = a range of 2523-4350 dmg
13 shots land as Crit x5 - ((29*13)*5) to ((50*13)*5) = range of 1885-3250
26 shots land as Crit x4 - ((29*26)*4) to ((50*26)*4) = range of 3016-5200
For a total of: 7424 to 12800 dmg per minute
Once again, sneak attack doesnt crit so we add that on for a total of (21*126) to (126*126) for a grand total of 10070 to 28676 dmg per minute, or 168 to 478 dmg per second.
So, as we can see here.. The dmg spread, is very close together. It all depends on your flavor of kill, the greatbow dealing slightly more per second than the repeater.
