I've had someone rush over and heal me up to full if I took on more than I can handle, and have likewise done the same, mining grade 3 thanalan soil other day, a low level ran in to the fate there and died, I said in say I'd raise them just need to switch out of miner and wait for cool down reset .
Once it did, raised them, healed them, then helped them with the fate then changed to miner and got the soil
