Great overall, sometimes have issues resetting aggro and potion management. For example if you plan to use divine magic potions to boost yourself to barrage it doesn't drink another sip before the effects run out, leaving you boxing the skeletons.
Pretty solid at MM1 tunnels. My only recommendation would be to add antipoison support. Sometimes when re-aggroing the Skeleton Monkeys, it'll get poisoned. Other than that it seems pretty good to me.
Does what it says it does, but thats literally it. You can only use prayer potions or it teles you out. You have to manually set it up everytime. Idk if the price is exactly fair, but to each their own.
