My apologies i had missed this.
just to confirm, the cure me setting works by casting the cure me spell when the venom starts do deal 10+ damage and will not cure the venom instantly, as requested by some Ironman users. This is because the venom can infect you immediately after being cured and is not preventative.
If the script cured your instantly you’d be spending half the fight casting the cure me spell and it would get a bit expensive.
looking at the logs, it is detecting you’re venomed so that appears to be working and as you mentioned it’s not casting it early enough this might be the reason why - it is waiting for the venom to get worse.
I could potentially have it cast it earlier but casting the spell immediately turns out quite expensive due to the almost immediate venom by zulrah
