Raids 4 weapon concept idea

Recently it came into my mind an idea for a new concept of weapons in the game, and I think it could fit the new megarare from the upcoming raid. It is a weapon that has 2 different attack styles:

Style 1: Hit boss, like any other melee weapon.

Style 2: Every attack consumes a bit of special attack, say 2 or 3%, but deals considerably more damage.

The idea behind the 2-3% is that you have a limited amount of "strong" hits, while making it sustainable while equiping a Lightbearer, giving these 2 items a level of synergy. However, if you need more damage for a shorter time, you can use it with Ultor, but it will eventually drain all your special attack energy.

Think of this as an auto attack that uses mana to empower it. This opens up a range of possibilities for future weapons, such as using special attack energy to make attacks AOE, or longer range, more damage, etc.

The suggestion is just this concept, you can add it to any of the actual weapons that people have suggested here.
