Your thread make me curious about thrall damage, it seems that they only use the damage of the bow, but not the damage of the arrows. On the other hand they benefit from armor penetration bonuses and statut effect (poison) of arrow. That why you needed 52 shots without any arrows and 50 shots with dragonbone arrows on Elk king, thrall has +9% armor pen according to the arrows.
I tested something with Devkit help. I checked the NpcStatTable and picked up a monster with low HP :
- hyena spotted : 96 hp, armor 22
If I use bossonian bow with blunted arrow, damage 17+1 (I used blunted arrow to have something like no arrow damage bonus), I should theoretically shoot 96/18 = 5.3 arrows, but I have 7+8 = 15% armor pen, so I should need less than 5 arrows.
In game I need 4 shots to kill hyena.
From there I tried with thralls equipped with a 18 damage bow, without arrows and then with dragonbone arrows on the same hyena.
- Black hands archer lvl 1:
-No arrows : 10 arrows : 96/10 = 9.6 damage
-dragonbone arrows : 9 arrows
-1 arrow due to + 9% armor pen bonus, but archer lvl 1 still does less than half of the damage than a player with same bow damage stat.
- Black hand archer lvl 2
-No arrows : 9 arrows : 96/9 = 10.7 damage
-dragonbone arrows : 9 arrows
archer lvl 2 still does half of the damage than a player with same bow damage stat.
- Black hand archer lvl 3
-No arrows : 7 arrows : 96/9 = 13.7 damage
-dragonbone arrows : 7 arrows
archer lvl 3 still does less damage than a player with same bow damage stat.
- Black hand archer lvl 4
-No arrows : 6 arrows : 96/6 = 16 damage
-dragonbone arrows : 6 arrows
archer lvl 4 still does little bit less damage than a player with same bow damage stat.
Now lets try with Forgotten Tribe archers :
- Forgotten Tribe archer lvl 1:
-No arrows : 8 arrows : 96/8 = 12 damage
-dragonbone arrows : 8 arrows
This guy is stronger than an Black hand archer lvl 2
- Forgotten Tribe archer lvl 2:
-No arrows : 7 arrows : 96/7 = 13.7 damage
-dragonbone arrows : 7 arrows
This guy is equivalent to Black hand archer lvl 3.
- Forgotten Tribe archer lvl 3:
-No arrows : 6 arrows : 96/6 = 16 damage
-dragonbone arrows : 5 arrows
-1 arrow due to + 9% armor pen bonus
This guy is equivalent to Black hand archer lvl 4.
- Forgotten Tribe archer lvl 4:
-No arrows : 5 arrows : 96/5 = 19.2 damage
-dragonbone arrows : 5 arrows
Finaly, this guy is stronger than Black hand archer lvl 4, but still do less damage as player with same bow with “no arrow”.
Let’s try best archers of the game, Votaries :
- Votarie archer lvl 1:
-No arrows : 7 arrows : 96/7 = 13.7 damage
-dragonbone arrows : 7 arrows
This guy is equivalent to Forgotten archer lvl 2 and Black hand archer lvl 3.
- Votarie archer lvl 2:
-No arrows : 6 arrows : 96/6 = 16 damage
-dragonbone arrows : 6 arrows
This guy is equivalent to Forgotten archer lvl 3 and Black hand archer lvl 4.
- Votarie archer lvl 3:
-No arrows : 5 arrows : 96/5 = 19.2 damage
-dragonbone arrows : 5 arrows
This guy is equivalent to Forgotten archer lvl 4.
- Votarie archer lvl 4:
-No arrows : 4 arrows : 96/5 = 24 damage
-dragonbone arrows : 4 arrows
Finaly this guy do same damage as player with same bow without any arrow damage bonus.
Conclusion :
Player will always deal more damage than thralls even with 0 accuracy. Arrows are pretty useless on thrall, cause they ignore additional arrow damage and only bonuses are effective, so snake arrow is the ONLY interesting thrall ammunition choice because of the poison stack effect AND the +8% armor pen.
I also tried full stygian raider armor and Eye of the khan bow (+14 accuracy) on Votarie archer lvl 4, he still need 4 arrows to kill the hyena. Accuracy is useless on thrall, the only interesting armor bonus for thrall is vitality, others do nothing.
