Jabba's lead has more damage reduction for hutt cartel which adds together with the datacron, causing the 1 damage you've seen.
Don't know about the subsequent hits damage reduction though. Edit: just thought, does the assist call have a damage reduction built in? Like "all allies assist doing 30% less damage". That could add together with the datacron, just like jabba's lead.
If you watch the times when the 75% damage reduction is not happening, the hits are in the thousands. If a hit would be 4000 without the reduction, it should be 1000 after the reduction. For a 75% reduction to result in a hit that does one damage, the hit would have to do 4 damage without the reduction. That is simple math. If you are saying they are taking a 30% reduction and adding it to a 75% reduction to get a 105% reduction, that is an incorrect way of calculating this function. Each percentage should be calculated in series. First do the 30% reduction = 70% damage. Then do a 75% reduction of the 70% = 17.5% damage.
Each damage reduction is being applied independently, to the damage of the attack. These examples all as if 1000 damage was going to be done.
-75% Datacron applied= 750 less damage.
-30% jabba lead applied= 300 less damage.
1000-750-300=Minimum damage 1.
-90% Mon mothma lead assist when calling ability applies damage = 900 less damage.
-30% jabba lead applied= 300 less damage.
1000-900-300=Minimum damage 1. (There would be an extra -750 here too if the tm is over 50%, but it makes no difference)
-45% Mon mothma lead assist when calling ability does not apply damage = 450 less damage.
-30% jabba lead applied= 300 less damage.
1000-450-300=250 damage. (Over 50% tm would give another -750 for 1 damage again)
You can decide for yourself how the maths should work, or you can look at the results and figure out how the maths actually works.
The Kyle katarn sabre throw in the video does damage in the first instance because kyle has jedi knight, so the first instance of damage gets +75% damage, canceling out the datacron reduction but the second instance does only one damage because krrsantan does not have the force influence debuff, so there is no +75% on that one.
Your first example is how the damage is being calculated with the DC. However, it is incorrect to do it this way. The decreases should be sequential, not additive. 1000 damage - 30% = 700 damage. 700 damage - 75% = 175 damage. If you were going to a store that had items on sale for 30% off, and then they offered a 75% clearance discount on top of the sale, you wouldn't get the items for free. That's not the way anyone would calculate a percentage off a percentage. I would mark my students wrong if they did it the way you suggest.
And CG knows this, because your second example is not how the damage is calculated in game without the DC. My characters are NOT doing 1 damage when the DC is not active. If you watch the video I posted, you will see that when the 75% DC reduction is not active (Krrs is below 50% tm) then my characters are doing damage in the thousands. It is not being reduced by 90% + 30% = 1 damage. It is being reduced by 90% and THEN by 30% (or vice versa).
All of the damage amounts in your video are in line with the kits involved.
Mon mothma lead reduced damage on assist, damaging calling ability or not. Jabba lead damage reduction. Kyle katarn sabre throw with jedi knight buff, but no force influence debuff on krrsantan. Damage reduction cron over 50% tm.
No bug here.
