This is my dream list for a Musketeer DPS tree.
I picked fun ideas because virtually anything can be balanced so it’s not too strong or weak.
Talents 1-5:
Laser Bullet:
When used this bullet will create a large, piercing laser beam that lasts 3 seconds.
Any enemies hit will take some damage.
Any allies hit will get a DPS buff for 8 seconds.
Bullet Master:
One bullet can now be “inserted” into the gun, changing its damage properties. This does not count towards your 4 equipped bullets.
Poison: Changes white damage to Poison and applies a weaker/shorter dot.
Ice: Changes white damage to frost and applies a shorter slow.
Weakness: Debuff is potentially always up but has less of an effect.
Laser: Changes gun fire to be a constant laser.
Renew: Damage removed. Instead allies hit will get renew for 2 ticks if shot.
Enraged Bullet:
The target(s) will do a significant amount of extra damage for 10 seconds, but will also damage themselves. This can be a great way to help the warrior build aggro if necessary.
The Specialist:
Make an exact duplicate of your gun (Duel wielding).
This would need a simple way to select bullets… but that wouldn’t be too hard to figure out.
Healing orbs are disabled while duel wielding.
Cannon Fodder:
Hold your guns together to merge them into a cannon. If shot, it activates a cooldown.
