Please spread the word: you are INVINCIBLE after accepting a non-LB raise.

[IttyBitty]

Actually you can move however much you want after being raised and still retain invuln. I do it all the time. You lose raise invuln after a set period (something like 3 server ticks, ~9 seconds), when you receive a heal/buff, or if you use an action or item.

Be aware that even if you don't take damage, you might still get debuffs associated with the damage. Getting 5 vuln up stacks raising into a load of stacked splats in O6S is no bueno.
