Thief 3 second invisible immunities not working properly.
Actually I just tested cloak and daggers and other invisibility abilities on my thief, the 3 second immunity starts when you cast your ability, not when invisibility ends, so there’s nothing to prevent you from using permanent invisibility as long as you have good timing. If the idea was to stop thieves from stacking invisibility instead of simply refreshing it as fast as cooldown allows, that is not functioning either. Because as long as the abilities you are using in combination is different, it completely ignores the 3 second immunity from the start, which means you can stack up to 9 seconds(12 seconds if you trait meld with shadows) with cloak and daggers, shadow refuge and blinding powder. So I’m not sure what was the actual intention of the devs of adding the 3 second stealth immunity, but it sure is not working in any way I can think of.
