So, for a certain Gym leader of E17, you have to carry a mon knowing ALL 3 water HMs with you... Which sucks, cause, in my Bug mono this means I have to carry my boxed-HM slave-Squirtle starter with me and fight a 5v6.... Or is there another way?
I kept Surf on the whole time (since Grenija was solely TM moves), so I just had to change to waterfall twice. Would have been unbearable if I tried it with Surf too.
I'm so used to Bugs that I had no trouble to beat Titania with only 5 of my current team. In my main save I haven't defeated Titania (still). But Bugs aren't the easiest type to cope with HM requirements...
