Question is, what gem do I throw in this beast?
It reaaaaally depends on your playstyle and spec. If you're not playing Sentry, your RSE is just fine. The Marquise Ruby is more for Attack Speed/Sentry.
When all is said and done, damage per hit is essentially the same between Calamity and Wind force. Just Calamity hits 25% more than WF. On a high attack speed WF build it will become very strong. windforce does have a higher max damage than the Calamity while having a loose damage range.Yes this is correct. On a regular hit basis, Windforce actually hits slightly harder than a Calamity due to the higher max damage range on a Windforce.
HOWEVER, where Calamity pulls out ahead is due to the 10%CC from Archery and 100% CD from Calamity and that's not even including the MFD bonus. Calamity produces better criticals and it's spitting out more of those.
(and yes, I simmed both a top-end Calamity w/ Marq and a top end WF w/ Marq.)
So to conclude. It comes down to your playstyle and spec. Windforce pulls out ahead for Sentry specs and for general damage purposes, Calamity or Manticore pulls out ahead for overall damage. All are competitive.
Weapon selection at the top end boils down to price. The top end WF I simmed was 980m, Manticore was 1.2b, Calamity 1.3b. It may be best to go with a Calamity for the extra 320 million b/c it can still do over 1m DPS w/ Sentry but has additional benefits such as more APS, CD and MFD proc.
Let's do some actual numbers with marq rubies.Perfect windforce
1818 dpsPerfect calamity
2002 dpsClose to perfect rare hellion
(300-398 roll that I know is possible, didn't find reliable maxes):
2096 dps, slightly more with a perfect onePerfect manti with 2 rubies
You'll notice that windforce is the weakest even when not counting crits. Even with the archery bonus(that takes away a passive) it's 2091dps, worse than all of them since calamity gets the marked for death amplification.
Whatever IAS you add from non-weapon slots will just be a constant multiplier on all of these figures. If you have a combined 50%, calamity will be at 1.78 * 1.5 = 2.67 aps, WF 1.55 * 1.5 = 2.325, both crossbows 1.22 * 1.5 = 1.83. WF DOESN'T BENEFIT FROM ATTACK SPEED ANY MORE OR LESS THAN EXCORCIST OR HELLION. WF DOESN'T DO MORE DAMAGE WITH SENTRIES THAN ANY OTHER OPTION.
+damage from jewelry slightly favors Calamity over WF and WF over 2h crossbows.
Windforce is worse for any single imaginable purpose than any of the other options(ok, looking cool and knockback excluded). It'll do less damage than those. And they get up to 100% extra CD. And they have an extra passive slot. If all you have is 10m then windforce will be the best option simply because it is borderline worthless.
The +150/300 from ruby scenario only happens if the weapon +min alone makes weapon base min=weapon base max. no a ruby can do that
That's a heavy crossbow with 15-17 base.
15+19 = 34 min, max set to 35.
35+19 = 54, final damage 34-54.
If the gem added 19/38 damage would be 34-55.
It's 19/37 added, aka exactly 19/(38-delta+1). In the OP I didn't include the +1 that the max gains from getting pumped up to min+1, I'll give you that :)
To avoid confusion with + -1, if it was:
15-19 base, delta is 4
15+19 = 34
Max = 34 + 1 + 19 = still 54.
Damage added: 19-35, that's exactly 19/(38-delta+1)
Just noticed it could be any heavy crossbow between 15-17 and 15-19 :)
