if you jump into the water by booty bay, you can still tab or just look about for a horde on one of the walkways.
being a caster myself - its really fun to cast DOts on horde or fear is hilarious too.
if you get in the right spot - the guards will not bother attacking you cause youre alredy quite far out
and even if they do start to swim after you, they will lose aggro eventually.
if nothing else - fear horde an sit back in the water an laugh
