Guild Wars 2

So there is this cave filled with spiders in Caledon Forest, and you can pick Redcaps in there. Picking them makes you grow or shrink in size for a short duration. I was wondering if you could introduce this effect by consumables (maybe even Endless ones!) just for longer durations. Like 5-15 minutes, and maybe the Endless version could work like the Endless support tokens used at Cutthroat Politics, in which case if you double clicked the button, it removed the support buff from you. This way using the Endless consumable would return you to your original size, while the regular 1-use ones wouldn’t. Of course you couldn’t use it in WvW or PvP, that would be just nonsense. Not sure how it could be rewarded though. Maybe MF recipes? Artificer? Meta-achievement reward?
