So, the organizers of the tournament allow you to bypass the quest about "walking on water"! If you openly say that "walking on water" is not mandatory, then I am in SHOCK!!! Seriously, why make things more complicated...
Bypassing is prohibited. Doing without is allowed. If you acquire the "Walking" spell earlier than you remove the guard, that will be a violation. If you don't remove the guard at all and leave everything as it is, that is your right. Quests are not mandatory to complete. You just can't bypass them. What else is unclear?
Can someone tell me: why was this quest put in place then?! Money - why?
And I would like to end the discussion of the tournament rules here. Well, it can't be made any clearer, right? :)
