Ehh, I've stopped using the thing altogether. I'd probably use it with Oak for the combo, and QoT too (maybe). Maybe Erebus, since I could proooobably do without tele scrolls. But otherwise I can hardly justify the room for it.
My mid to late game inventory looks like this
Capture Lock
Teleport Scroll
Sigil of Vitality
The first one, to LOCK THE F****** FLAG. The second one, while LOCKING THE F****** FLAG, you can get out, go to the other side and LOCK ANOTHER F****** FLAG, or just go where're you're needed in general. And the third one, since I'm usually stacking health, getting +8k instantly with the sigil allows me to escape a gank, or get a kill under heavy fire and get out of harm in time. Most importantly, it can't be interrupted. Seriously, can't live without those things anymore, so useful.
No room for HoL.
