5/5 been using it for 40 hours or so to gain 90 str.
It does very well in prayer flicking, and dodging the falling stones from the ceiling. I started at 60 att/str and it was having the time of its life killing the boss and its minions.
Once you get a bone weapon it absolutely wrecks anything in its path. The only thing I've noticed is that when you're using mage/range weapons, it will not as often dodge the falling rocks, and you'd take some damage, but that is about it.
I'd love to see a setting to what to spend spines on as a dropdown where you can choose which reward to pick from, its a niche setting, but would be awesome to see in action.
I do agree ideally the bot should have an option for minimum food before starting fight; Honestly it's just been sidelined because technically the main purpose for the boss is the XP from fighting it and not necessarily the drops, so technically (as long as you have a bone weapon) it's still efficient XP training fighting a battle that it will need to leave.
That being said, that's just kinda why the feature was bumped down in priority but I should still add it (especially for people pet hunting, getting first spine etc). Will try to bump up on my list (just a bit swamped with the Cuppa Moons of Peril release right now)
