Aura ideas for Vampyrism, Penance, and Eq

Having these auras obtained through things like ports, or god books honestly leaves a bad taste in my mouth (ports suck and changing the god books could be really annoying, especially for irons). So I have an idea for them; potions. I don't mean new ones either, I think if we rework some of the lesser used pots we could easily see this working so here is my ideas;

• Vampyrism - Zamorak Brew/Super Zamorak Brew, This one feels obvious due to the ties between Zamy and Vamps now and how useless the Zamy brew is right now. SO maybe we extend the timer for how long a zamy brew last per dose (maybe like 15 mins per dose) and each dose will provide vampyrism on top of the debuff it brings (or maybe just get rid of the debuff but keep the HP damage)

• Penance - Sanfew Serum, This one is a bit more of a stretch TBH but I think it still works. Sanfew Serum would keep it's base effect but have this added in, again I think a 15 min per dose timer would work, but the timers can be tweeked as however felt necassary

• Equilibrium - Camouflage Potion, This one I feel should be entirely reworked (maybe make it a Guthix Brew as we don't have that "officially" atm). This could exclusively just be equilibrium because the minimap hiding is useless atm save for some really few and far between extreme edge cases

I'd love to hear other people's thoughts on this. Like I am open to hearing what other ideas people have, I just don't want things to be stuck into ports, and I don't like the idea of these becoming permanents as I have seen that thrown around a bit and that would be way too OP.
