Also, people have a tendency to immediately say CS items are overpowered before they give it proper thought. Or they jump to conclusions when they get owned by someone in muldia. I pvp daily in muldia, and being a sniper myself, i pay extra attention to other archers to compare my strength. Now, i can list all of the active muldia archers that "hit like a truck." Out of the 6 snipers/hunters that immediately comes to mind, only 1 of them could be considered a regular CSer. Also, how are you able to make the assumption that their weapons are +7? There's no visible evidence if a weapon is +1-7. Only at +8 can you make a tell. Jumping to conclusions much?
Also, you are wrong about muldia weapons not being able to compete. I'm in the works of replacing my +6 ice bow (achieved and obtained through in game gold) with a guardian bow. Which, when done will do a lot more damage than my current ice bow even at just +4.
First and foremost, let me explain how the dark bow works.
At +7, and people WILL have +7 dark bows, I guarantee it, this is how it will work:
26% Damage Recoil Reduction. Normally with darkness aura you take half of the aura damage back as a hit to yourself. With a 26% reduction that that recoil, it will be 37% of aura damage done taken back as recoil. So, if you hit a 100 with aura damage, you will take 37 damage to yourself.
15% chance to Weaken. This is self-explanatory more or less. I chance to weaken that is almost double the chance to freeze on ice bow, so I know it will hit a lot since I freeze a lot.
A 100% chance to absorb 10% of the damage you do as regained life points. This means if you do 1000 damage, you will regain 10% of that, or 100 health back.
Also, a 16% added resistance to frost.
All in all, what this means is that the darkness bow has a good chance of being OP. Why? Let's test this scenario:
I hit a player for 800 normal damage and 70 darkness aura damage with a +7 darkness bow. I will take ~26 damage as recoil, and gain 80 damage from life absorption. This will come out to an added 54 life with above attack. I will also have a chance to weaken my opponent with this attack. This means that with each attack I will gain life no matter what, and I will be doing massive damage to my opponent.
Secondly.... You are completely wrong about +7 weapons not being noticable. It is at +7 that CS weapons start to glow, not +8. Any glowing weapons you see are +7 or higher cash shop weapons. Jumping to incorrect conclusions much?
And people aren't so much saying that damage-wise Muldia weapons can't compete, it's more of special ability wise they cannot. There is no special ability on the Guardian Bow. All you will get by making that +6-7 is added damage, which is nice... However, as stated above with Ice bow and Darkness bow you have skills like Weaken and Freeze, which make all the difference in PvP.
