Interesting, I would have thought that a GS would be superior with piety and void; apparently not. I did some preliminary tests yesterday using Z-spear/Void/10 or 15% Strength Prayer. Obtained around 84 crimsons/hr, which isn't too far off the 88 crimsons/hr when using an SGS. Seems that there is less than a 10% variance in crimsons/hr using either weapon, with or without piety. [Numbers were scaled to 60mins from crimsons obtained within the 54min lifespan of a unicorn familiar] Guess I'll unlock Piety later this week, do a few trips and crunch some numbers, and post the results when I get them. BTW, any thoughts on using Piety only after freshly potting (say till ~112), then switching to 15% strength until repotting at 108, just to optimize the usage of prayer pots? I don't intend to Dharok, haven't needed to even flick on protection prayers in my last 5 waterfiend trips using void, and would gladly pay a measly 10k for 10 more crimsons per trip :D
