Study of Atrox Old
Right, here's one to make your brains hurt on Christmas morning!
We observed some odd results whilst testing armor decay with atrox which suggested the long-standing 33% Impact, 33% Cut, 33% Stab is not accurate. Its a pretty tough one to test, as separating Cut and Stab is very difficult when the mob does both. I got there in the end though. Feel free to skip the reasoning parts and jump to the conclusion, but I include it so someone can check my logic.
Naked vs Atrox Old
Min Hit: 28.3
Max Hit: 55.6
So Atrox Old has 56 max damage.
Goblin vs Atrox Old
An 18.4 hit caused me to decay 0.822 in Goblin. That corresponds to exactly 12 damage absorbed.
So we know that in a 30.4 hit, at least 12 of it is Impact. Thus Impact is at least 12/30.4=39.47% of the damage. Thus the max impact is at least 39.47% times 56 = 22.11. But we know the max impact must be an integer so it must be at least 23.
Vigilante vs Atrox Old
Code:
Hit Decay Absorbed
-----------------------
7.9 2.398 28.3
16.1 2.841 32.3
Right, the first hit was for 36.2. We know at least 23/56=41% of that must be impact. That is 14.9.
However, we also know that vigi has absorbed 7 Impact, and since we were hit for 7.9 (some or all of which could be impact) the trox did no more than 14.9 Impact.
The two facts taken together imply the trox did exactly 14.9 Impact, which implies that the max impact damage of Atrox Old is 23.
-----------------------
The second hit was for 48.4 damage. We now know that 48.4*23/56=19.9 of that is Impact, leaving 28.5 for Cut and Stab. We absorbed 32.3 damage, 7 of which was Impact. So we absorbed 25.3 Cut and Stab.
Since we're protecting 14 Cut and 14 Stab, and since we know there was 28.5 Cut and Stab of which we protected 25.3, we know that one of Cut and Stab did 17.2 damage (Thus we took 3.2 unprotected which adds to the 12.9 unprotected impact to make the 16.1) and the other did 11.3 damage and was totally absorbed.
56 x 11.3 / 48.4 = 13
56 x 17.2 / 48.4 = 20
Thus an Atrox Old does 23 Impact, 20 Cut/Stab, 13 Stab/Cut.
Predator (L) vs Atrox Old
Min Hit: 2.6
Predator protects 11 Impact, 9 Cut, and 6 Stab. On a min hit from an atrox old it is facing either (11.5 Impact, 10 Cut and 6.5 Stab) or (11.5 Impact, 6.5 Cut, 10 Stab).
Clearly it must be the first which has a min hit of 2.0. If it was the second the min hit would be 4.5.
Conclusion
Atrox Old does 56 damage of which 23 is Impact, 20 is Cut and 13 is Stab.
That is 41% Impact, 36% Cut, 23% Stab.
