I've often felt that having a consistent bonus-action attack (or other mechanic) is 'optimal' in builds during combat. The more actions/options you have, the 'better' you are able to handle different situations or deal more damage.
Traditionally, in order to have a consistent bonus-action attack, the Dual Wielder feat and Two-Weapon Fighting fighting style was a common source for melee-focused builds. But there was a pretty big investment in doing so (feat and fighting style).
Eberron's new double-bladed scimitar seems to bypass this investment, but does it actually? Is it better or worse from an optimization and damage output perspective?
A double-bladed scimitar is a martial weapon, weighing 6 pounds and dealing 2d4 slashing damage on a hit.
It has the two-handed property and the following special property:
- If you attack with a double-bladed scimitar as part of the Attack action on your turn, you can use a bonus action immediately after to make a melee attack with it. This attack deals 1d4 slashing damage on a hit, instead of 2d4.
Another thing to consider is the similarity of the scimitar to that of the scimitar of speed, but without the +2 property.
