I happened to notice this a day ago or so about IC/OoC. While the current formula for IC duration (by seconds) is 7-(0.05*Vit), but something is not right here. How so you may ask? The IC timer only scales with characters’ vitality, but without the equipment bonuses.
Example: A maxed Ninja (60 Vitalities to start with, that translates to 4 second IC duration) with Sawblade + DCircle + Fitted Constructed Vest + UBVit gives total of 85 Vitalities. In theory, we have 2.75 seconds of IC duration for that Ninja.
Now getting hit by O2’s sun explosion that deals 100 AP damage per bullet split. Hovering the cursor to sword icon, we see that the IC duration for a Ninja is still 4 seconds. Yes, I kept my cursor on the icon and get hit again, still 4 seconds.
Is this a coding error, an intentional feature or somefing else?
Edit: Experimented it again and it turns out the formula that was disclosed from the patch note is wrong.
