Before you enter a bonus mission you are given a weapon. When you enter the mission your stats (max health, energy, etc.) are set to a certain level. My question is, does adding mods to the weapon have any affect on your stats when you enter the mission? Does it matter if you change your attributes?
For example, before you do Saul's Story, you are given a basic smiting staff requiring 9 smiting prayers, with no mods on it. Does it make a difference if you change your attributes to put 9 in smiting? Would adding, say for example, an Insightful Staff Head and Staff Wrapping of Fortitude make any difference?
(I'm guessing, no - and I'll probably find out by experimentation soon anyway.

(I'm referring here to weapon you get before you enter the mission, not the weapons you get as a reward afterwards)
