I used super combat potion (not divine) and preserve personally, what preserve does, is when you are going to lose a stat degrade, itll add 50% extra of the time.

so your pot lasts 50% longer.

I used Dragonhunter lance and full dps gear I would get 4-5 kills per trip and id lose i dont know 5 or 6 of the stat points i gained. I would have had to take two sips of divine pots otherwise, I personally don't enjoy the divine pots and the dps you lose via regular Super Combat is insanely small, probably not even noticable.

Thanks all for the help..

Just one last question , does it affect anti fire potion? is it consider stat boosting?

Negative
Would been nice tho

Fair enough definitely worth using if pp isn't an issue.

Worth mentioning OP if you're trying to do lazy flicking with quick prays you're just gonna turn preserve on and off effectively making it useless so don't do that
