tldr:
perks: Hitman's Opportunity + Swift Deliverance + Elemental Balance. (comparison below)
ㅤㅤㅤ- second evo can take whatever u want
ㅤㅤㅤ- can also take Stalker's Resentment if you are set up for it.

quick note: fire rate is double dipped on incarnon bows, so fire rate is really strong. highly recommended to have a source of external fire rate with this weapon. detailed explanation below.

options:

• if no arcanes, run as is with serration over bane (serration beats bane without arcanes)
• if no primed bane (with arcanes) there is two options:
  ㅤㅤㅤ- option one: go critical delay + vile acceleration over bane + point strike, this is a lot of dps but less dmg per shot
  ㅤㅤㅤ- option two: go normal bane / hammer shot / serration (in that order of priority) over primed bane, less dps but more dmg per shot
• galv scope can work on this gun, use at your own preference (would replace [Point Strike]) (note: it doesnt proc on slash or heat takedowns)

fire rate thing:
basically, fire rate affects charge time AND reload rate on incarnon bows because of how the incarnon "magazine" works. its actually more dps to go [Critical Delay] + [Vile Acceleration] over point stike + [Vital Sense] (or [Point Strike] + bane) but I feel like that's a bit too sauced up to recommend to people (its a lot less dmg per shot, but u COULD spam them so fast its more dps). you can test in simulacrum with excessive fire rate and see that there's really no limit to how fast you can spam it.

^ no evolutions numbers

other info:

• i calculated for slash, but, heat has the same equation but instead of a 0.35x multiplier its a 0.5x, so basically this math will have the same relative differences for heat as well. (bascially, whatever is best for slash is usually also best for heat)
• if you are getting a riven, try for one that can replace a mod already in the build (like crit chance or crit dmg, or cold/tox) + fire rate (and + other op qualities like multishot, etc if possible)
• galv aptitude is bugged on incarnon dread giving a multiplicative bonus instead of additive (big dmg - wiki)
• split flights is viable for galv chamber
• can use terminal velocity instead of vig supplies
• why no sharpshot? bc its less dmg with viral build because u need base dmg for slash
  ㅤㅤㅤ- basically, 1+3.6 > 1*4
  ㅤㅤㅤ- here is my slash calculator https://docs.google.com/spreadsheets/d/12OeFBa-LNXPRk97FoRe-G2lq8n1pTnZAs45S_APy8h8/edit?usp=sharing feel free to copy and use it
• if you are going to be priming with viral, can replace viral mods for something better (like serration + fire rate)
  ㅤㅤㅤ- if you do do this and use serration, then u can replace prim merciless for sharpshot because (1+1.65)*4 > (1+1.65+3.6)
