hell is 93% chance to ohko not counting any other factors
if you're using hell on a multi-target/multi-hit weapon the special will be reduced based on the weapons (usually how many enemies targeted or shots the weapon fires)
something like a vulcan hits 3 times per attack so the special is reduced to about 33% effectiveness per attack
partisan and sword have variable reduction iirc and it's pretty bad for any special that isnt sacrificial (charge, spirit, n berserk are unaffected by reduction since there is nothing to reduce)
enemy EDK is what really affect hell weapons
pso world bestiary for lack of better info source
hp does not factor into hell at all which is why it's such a good special for fast clearing certain quests
V501 increases hell activation rate by 50% (i assume after other shit is calculated such as you having a 30% chance to kill an enemy after edk calculation it becomes 45% ill prolly be corrected by someone)
V502 is 100% increase so double chance (if you even have a chance to hell the enemy in the first place)
your best best is to use single target weapons such as raygun for hell until you can get s-rank weapons with hell (which are not affected by the multitarget/hit reduction)
someone correct all the mistakes kthx
