One of union player saw few dragon-helms in cave and, he asks help for defense.
We said him blocking cave's exit ASAP,but they entered inside already.
Fortunatly, cave's outsides was palled,so we tried to make wall with new char with hope invaders return.
[TIME(PM)(GMT +09:00)] status
[8:40] defense started. and call all unions and friends for walling.
[9:00] walling pally with chars complete but they didnt return;
[9:09] half of pally destroyed 1 of our ranger logged on.
[9:15] call all allies for counter.
[9:20] cave entrance blocking succeed. and start ranger's battle.
[9:25] lagging started, our old soldier find they tried to crash server,so attack light armored but not well controlled.
[9:30] many of wall chars dead and wall line become larged. so call other friends for more chars.
[10:05] allies arrived. and horrorble lagging start.
[10:20] first knocked out.
[10:33] entrance blocked character disappeared. and 1 invaders escapes.
[10:35] other 4 invaders 'disappeared same time' in next frame.
[10:44] last invader(lure character?) escaped and 2 of our warriors chased, but invader have much support inside cave. our chase team retreated.
Thanks allies,friends and unions for helping. if not, char wall would broken and the village destroyed.
I didnt expect over 70 ppl comes for help, Thanks all helps from warrior to only 1 new char.
We couldnt succeed our bonus mission,but catch main defense mission. Congratulation alls.
(And I hope the magic 'World Stop' published to public like auto hearth. Omg....

So what magic is best for defending six ppl invaders not to call 70+ ppl everytime. )
