This is a mostly a rework of the Martial Mastery Tree.
I wasn't happy with the Weapon Stance talent (which provided 3 new stances), and have replaced it with Weapon Bond.
Weapon Bond is a passive, which keeps track of kills you've made with any given weapon.
Already enchanted (greens, blues, artifacts, etc) will slowly gain base damage and accuracy.
At 1 point, it requires 1 kill, then 10 kills, then 100 kills, etc to receive a +2 bonus each time.
At 5/5 points, it requires 1 kill, then 2 kills, then 4 kills, etc to receive a +2 bonus each time.
However, the most interesting feature is if you are using a plain white unenchanted weapon (or shield or gloves - I think) it will turn it into an Artifact weapon. It will gain stats in the same was as an enchanted weapon. But in addition, it can significantly stronger benefits as you kill unique bosses (in code turns rank 4 and greater). It will gain APR and crit chance after 1 boss kill (and updating any time a boss is killed). The magnitude of the benefit is dependant on how many enemies in total are killed. At 4 bosses it starts adding crit damage multiplier and physical penetration. At 16 bosses it improves attack speed. At 64 bosses it adds a stat bonus. At 256 bosses it adds global speed. Over 1000 bosses will add resist all. Good luck finding 1000 bosses. :)
Combat Grip was improved so disarm chance is based on Accuracy, and scales up to about 25% at around 100 accuracy and 5/5.
Parry became Master Parry, and is now an instant cast, 1 turn (effectively 2) evasion effect, which has a chance to counter attack against anyone who misses the user. So if 8 enemies attack you, you could counter up to 8 times if they all miss. It is possible to reach 100% evasion and counter rate at very high accuracy. Has a 10 turn cooldown.
Let me know what you think in the addon forums thread.
