free RK? Really? Actually, i recently found a duplication glitch that i don't know how i did it... lol. I got 20 extra buffs of RK from it though (only one extra item, lol). I love to buff people up with it. as in buff up, i mean give an extra 50 energy:)
The RK rainbows all start with 20 uses of Random Kindness that give a boost of 50 mood or energy to the recipient. There's a little blue wear indicator underneath the rainbow to give you an idea of how many uses are left. You can also hover over the RK to see how many uses are left.
Is that what you experienced, or was something else going on?
Yeah, if you can establish a cooperative gathering relationship with another player in the game, RK is one of Glitchs hidden gems. Carry a few each and go mining or harvesting. You can regularly stop and RK each other multiple times at no cost with no cool-down period.
Good idea WalruZ, sometimes if you RK a stranger they will RK back, but it doesn't happen often. I've never tried, but you could always ask to be RK'd if you are low on energy and see what happens.
