I have been training here for a bit if you are going to write it (I used pbot script here, but all you really need is this)
1) Soul split at Half HP-Full HP
2) Prayer renewal support
3) OVL support
4) Ability/Momentum support (Don't support the healing one, as in a couple weeks that is being nerfed)
5) Ability to pick up Crimson charms (They actually drop a lot of valuable stuff, I have my script currently picking up water orbs and those are like 5k drops that are fairly frequent (noted))
6) Prayer Potion support, sometimes you run out of prayer faster than renewal works
7) Cannon support is not needed, tbh it slows it down cause you pretty much one hit them with your own gear
8) Moving around to different rooms allows for the argo to never end
Here is the guide I used:

All of those features aren't necessary but it does make the trip "better"
Sorry lol just wanted to point out it isn't the easiest thing to make ;p but if anyone can do it you can haha
