Using protection spells, should i wear

 

monks robes and have +19 pray and +40 magic

 

or

 

wear mystic and have +9 pray and +75 magic

neither matter - the tunnels/tombs automatically drain ~12 on intervals, and the drain from using the prayer itself is nothing compared to it

 

 

 

you're only maging the brothers, who have negative mage def - you dont need mage att. mage in armor

I use armor on torag and guthan without pray. I use magic on the other 3 so the extra atck helps..
