…that it's only 19 Bedlam attacks (when logic says "5s duration with 0.25s atk interval" lead to at least 20 attacks)
Description:
I simply divide 5 by 0.25 and it gives me 20. BUT:
#1 Remember these 3 damage instances/hit times (actual time damage received) we will need it later.
#2
#3 As first hit is possible 0.03s after cast
0.1 0.35 0.6 0.85
1.1 1.35 1.6 1.85
2.1 2.35 2.6 2.85
3.1 3.35 3.6 3.85
4.1 4.35 4.6 4.85
5.1
#4 As one man noticed we can't put straight 0.25s with 1/30 server tick time so his guess is that 19 attacks limited because of delay of 8/30 which is 0.266s (each attack takes 0.266-0.25=0.166s more). But #1 tell us hits are possible within 0.23s which is most likely rounded 7/30=0.233s. (so it might be coded to compensate delays)
ps: difference between cast-time and 1st attack, intervals between attacks are explained by enemy target's position and these factors:
Jex rotates around Dark Willow
The attack radius is centered on Jex
The attack projectiles traveling at a speed of 1400
