The Diablo 4 Barbarian's Whirlwind can keep the enemy vulnerable to increase its output damage. Please take a look at the Diablo 4 Barbarian Whirlwind group vulnerability skills below. I hope it can help everyone.
Going directly to the key point is the passive of revealing weaknesses.
As we all know, Whirlwind has a characteristic, which is that in a state of continuous guidance without interruption, it is counted as the next core skill in many mechanisms.
So I wanted to test whether this passive could make the continuously guided Whirlwind more susceptible to damage, so I canceled the acupoint strike and used glyphs to do some tests.
The conclusion of the test is that it is possible, but there are some limitations. It can be said that revealing the weakness is very similar to exploiting this glyph.
1. You must use weapon proficiency skills to cause direct damage, and then the next whirlwind attack can make the monster hit vulnerable for 3 seconds as long as it continues to be guided without interruption.
2. Any action that interrupts Whirlwind will cause Whirlwind to lose its vulnerability effect unless you use weapon proficiency skills to cause damage again.
3. After causing vulnerability to the same target for 3 seconds, whether it is the currently guided whirlwind or the whirlwind with vulnerability triggered again using the weapon mastery skill, it will not be able to cause vulnerability again (only for the mechanism of revealing weaknesses) ).
PS: Regarding this point, it may be that there is a CD like the one used, but I waited for a long time and did not find that it can be used again. If you are interested, you can test it again.
4. After using the glyph's 3-second vulnerability, you can then use weapon mastery skills + core skills to immediately trigger the 3-second vulnerability that reveals the weakness.
Therefore, my suggestion is to use the weapon mastery skill after the 3 seconds of using the glyph, and then continue to output. In this way, Whirlwind has a stable vulnerability time of 6 seconds to the group of monsters.
In addition, for the weapon proficiency skill, I recommend 2 points of Steel Grip, because this skill has a short CD and can be stored 2 times. When you are vulnerable to damage twice and have not killed the monster, it can be used a third time.
