1. Using Ritual Sword while you have your bonded Youkai installed or locked out via spirit chains will still summon it. You will not lose install or lockout when you summon the Youkai in this manner.

2. Detogate does not remove the voidgate, it just makes them invisible. They still shoot out dark damage if they're frayed, can be teleported too, and can be detogated again. They just can't be seen.

3. Bourneblood enchant on a weapon gives the legging enchant of +move when you're near an injured person.

4. Screamer, from the screaming tome, will remove silence even when you are under the effect of strangling etacof.

I just logged on to report the Bonded Youkai shenanigans, myself. Looks like you beat me to it.

But yes, confirming; If using a Single Bonded Youkai for Installing, Ritual Sword will still summon it.

These have all been corrected, with the exception of Screamer. I think letting Screamer ignore Etacof gives it some unique utility, since its effect is quite costly.
