Changing clothes, Different rooms
I bet on 17 linked issues from @Rai99. Who says better?
Bet 9 on clothes change and 6 on rooms/areas @Rai99 .
Over/Under 17? Gonna bet on Over too.
Your suggestion is pretty vague in terms of what you have in mind, but here are some similar suggestions I think.
Clothes(14): #107, #460, #612, #703, #1076, #1461, #1656, #2270, #2466, #2811, #2905, #3090, #3385, #3690, #3770.
Room Decoration(15): #312, #800, #845, #908, #1336, #1793, #1891, #1933, #2176, #2220, #2496, #2769, #3182, #3305, #3770.
New Locations(8): #509, #676, #908, #1681, #1867, #2027, #2244, #2811
For a total of 37 issues.
Don't worry, I'm always like this.

Talk about overdoing it
I think they were a bit vague, so I covered room decor and new locations just in case.
17... What was I thinking...?
Based on evidence... it would appear that you were thinking "17".
You get a participation award.

(I've always thought that it was the wizard that was offering the sword to the warrior, that's why the roles can seem mixed)
