Here's my $0.02, reposted from Steam: http://steamcommunity.com/app/291650/discussions/0/618458030677032991/
Arbalest or War bow So because of the DR mechanic, I've quickly drown a conclusion, that it's benefitious to use high damage weapons, even if they are slow. I taught my ranger the soldier specialization, and got impressed by the ability to one-shot enemies. However later in the game I got really dissappointed by average results and loaded an old save before my decision of condemning the war bow. I would end at it, but my friend, RPG player with big experience in ADnD told me arbalest is actually better. So I started to count. War bow is three times faster than arbalest - that is, in the same amount of time you can either:
shoot an arrow, recover, shoot again, recover, shoot the third time and fully recover
shoot a quarrel, recover
So I'd expect arbalests to have 3 times higher damage in order to have higher DPS.
how average damage depends on accuracy and deflection on DR 7
how average dmg depends on DR when ACC = DEF
how average dmg depends on DR when ACC = DEF +30 How these values were counted? Most values were counted in Excel. Here's the main spreadsheet: download I took MIN/MAX damage values from my ranger as well as her ACC, and I took DEF value from a real NPC. Then I calculated chances to graze, hit, crit, based on ACC and DEF, calculated damage for graze (av. dmg/50% - DR), hit (av. dmg - DR), crit, and multiplied these damage values by their chances to occur. I'm not sure if I calculated critical damage correctly. For war bow it's easy:
average damage * 1.5
, but I had to guess how "-0.3 crit damage multiplayer" works - my guess was:
av_dmg + av_dmg*0.5*(1-0.3) = av_dmg + av_dmg*0.5*0.7
In cases where DR was high enough, I considered the mechanic that limits Damage reduction to 80%, by creating a simple table with all possible damage outcomes, damage reduced by DR completely and damage reduced by 80% and taking the highest value from these two, and taking an average of the highest values as you can see here: arbalest grazes against DR 16 I didn't consider any other bonuses / penalties.I also didn't consider how the game rounds values Do I miss something? If not, here are my conclusions:
because crit damage is a percentage boost, faster or higher damage weapon will not benefit from it more, unless DR is so high, that in some cases not only base, but also crit bonus of a damage will be absorbed by DR (not the case in my tests, the DR would need to be much higher than 16)
because arbalest has a penalty to crits, war bow benefits more from higher accuracy
because DR is a flat value, war bow benefits more from higher accuracy, as it decreases chances of grazes and criticals (so increases damage)
war bow has higher dps in any case except DR higher than 16 - in that case you probably want to switch to a wand or rod for their alternative damage type
while dps of war bow is higher, you must be aware, that arbalest deals its damage sooner; this way you can possibly kill a target quickly enough, to deny some damage for the enemy; also in case of your ranger's quick death, his total damage may be higher with arbalest, than with war bow
if you use a loading spell a lot, arbalest crits will be a decent way to start any encounter.
keep in mind that because arbalest will overkill enemies by higher amounts of damage, it means it will waste more damage and so it's real DPS decreases.
Final conclusions:
weapons seem very balanced in Pillars of Eternity; if you see two weapons of same quality and think one of them is better in all situations - you probably don't understand all game mechanics
weapons like arbalest, crossbow and firearms are designed with melee fighers in mind - the purpose of these weapons is to make a single strong attack at the start of the battle and then switch to another weapon, not wasting time to reload it
similarily to above, your ranged characters could have one of these weapons to start a fight and then switch to a bow or a wand.
If you find it interesting, I may also write about my experience with pistols and blunderbusses.
