You need to use Timewarp first for the projectile skill to gain that 62.5 MH% DMG. It's huge , especially for orb if Timewarp actually started working again.
The Timewarp increase skill by 50% MH and cosmic power increase it by a further 62.5% at (5) or 37.5% at (3).
At (5) cosmic power: 1.5×1.625= ×2.4375 (increase your projectile MH% by 143.75%).
At (3) cosmic power for PvP: 1.5× 1.375= × 2.0625 (increase PvP projectile by 106.25%).
You can see why it's extremely powerful for projectiles, especially orb if it worked. Because my orb would deal double its potential damage already .
My PvP orb currently dealt 1,615.03485% MH per 0.1 secs. With Timewarp+ cosmic power= 1,615.03485×2.0625= 3,331.009378125% MH DMG. You can imagine the insane DMG i would have got in the past had i built it back then. Sure one of the affixes would be sacrifice like no demonic existing or using it instead of Momentum or so.
I would have dealt code to 300k deadly strikes and 100k to 150k Crits more often than currently plus how orb procs constantly Proc combined at living force and Timewarp+cosmic power. Opponent would have easily be finished off.
Cronos4321 LOHKO Build was one shot arrow using discordance and it reached insane MH% like 3000% plus the Fire and bleed with discordance.
Midlumer orbit build would be 2× more powerful too .
Well it's not just orbs but orbs just get the most significant Timewarp boost due to such a hit frequency.
In my Seasonal Maidens' build, I'd have got cosmic power pet instead of pathfinder if the cosmic power+ Timewarp actually worked .
Stealth would be less used due to how much I'd use Timewarp unless i use Timewarp procs with cosmic power. Vanish mythic would have been used quite a bit.
The orbs MH in PvE on high floor× 2.4375 from Timewarp= 4,472.4023438614% H per 0.1 secs .
4,472.4023438614×2.4375= 10,901.480713162% MH.
over 10k H% per 0.1 sec or 100k% MH per secs.
The amount of DMG I'd deal on high floor would be like 30B deadly strike by orb and 19B crit DMG when Arcanist+Frostbiting and all the other pieces calculated in seasonal Maidens' build. The Frozen would easily deal way more than trillions or so. Easily maybe Quadrillions in frozen or even more. But the hit frequency of the orb would be easily 100B or so per second even better than 30B per second even though the 30B is still very powerful.
But even for skills like guidedshot, multi shot, throwsword, boomerang/whirling blades, toss/scalp , comets, pierce skill and barrage skill, Timewarp is extremely useful for any of those skills along with cosmic power.
Also cosmic power would double as an MP boost so I'd run out less MP of any of those discordance orb builds. I even had really almost perfect cosmic power legend pets but since it didn't work, it sucked.
