Date & Time: 2019/10/29 8:21pm server time
Frequency: Always
World name: Cerberus
Character name: Rubett
Retainer name: None
NPC name: None
Monster name: Striking Dummy
Class/Level: MNK 63 (but it's in pvp)
Party or solo: Solo
In-game time: 7:29am
Area and coordinates: Wolf's Den Pier (6.6, 5.9)
Housing: None
Steps:
1. Target a training dummy in Wolf's Den
2. Use Six-Sided Star (the PVP version)
3. The ability triggers the global cooldown. The global cooldown has the same duration as the recast of Six-Sided Star. 3.84 with 4 Greased Lightning, 4.8 without any.
4. As I understand, if the ability is supposed to trigger the GCD, the duration should still be 2.4 or lower.
