You get like 20-ish, per account just for logging in for each day of the event, 10 on the very first day and 3 on each subsequent day, lasted from 23rd to 27th in kMS, so 5 days, but I believe they were still obtainable for a short period afterwards, like two or three days. You can buy them from the Winter Event shop for 10 coins each, or 25 coins for 3. They were packaged in with protection scrolls, 5 Protects + 1 MEE for 25k NX. They also dropped from bosses, I'm assuming just the major bosses. I'm pretty sure normal protection scrolls work on them, because they're packaged together, but I don't know for sure.
During the event period, from 2PM to 4PM server time each day, the chance of passing an MEE is increased. Initially it was 2x the chance, but they changed it to +10% chance, as in 1 Star would go from 60% to 70%, not 66%.
