TRIBot does not currently offer script trials, sorry. For faster replies in the future, drop by the official discord:

Hm it seems I've removed the blowpipe a while ago. The ideal setup is to use the dhcb/lance, but according to the wiki yeah the next best is the blowpipe. I remember it used to be the dragon crossbow. I might be able to try adding it if you're willing to test and it times out on my end. DM me on discord if you're willing (link above), but I can't guarantee I will have time soon.
Thanks for letting me know, seems my GUI helper messed with the spacing. I've released an update for the Vorkath Slayer to fix this in V1.174 and one in the Zulrah Slayer as well (V3.0683)
I need the entire log next time, it's long so the snippet you posted doesn't contain the information I need. The script generates a log file on timeout, usually, but TRiBot has an official way to generate a bug report here which always has the information needed. Click the DEV icon in the top right corner of the client and then press the 'Generate Debug Report' button. It will create a .zip file and you can DM me that.
