v.160 - Black Heaven: First Chapter Update Highlights

The skill gives 3/6 seconds of invincibility when you revive for Resistance (BaM, WH, Mech). For all other characters, the Link Skill has max level 6 (2 for each Resistance) and each level gives 1 second of invincibility.

Thanks for the info.

And, oh bother.

Guess I'll have to do with just 2 seconds, from the Mechanic I already have.
