Hey, y'all! Alex 43 here! This month, for the official RSBANDB event, we are going to do something fun and unique!
PEST CONTROL!
Don't look at me like that. We're doing pest control. However, we're gonna try something that no one else has done.
TRY TO ENDURE THE FULL 20 MINUTES!
That's right. The plan is to take out only 2 or 3 of the portals and try to keep the enemies from getting at the void knight by any means necessary.
What good is that? Well, take a screenshot of the resulting veal points and the screen that shows when you protect the void knight and use it for bragging rights. Post it here and compare veal points to see who did he best!
Also, who could resist 20 minutes of easy risk-free maximum damage training? I certainly can't.
Here's the plan. On world 89, we'll all meet at the Void Knight Outpost.
From there, will search out worlds until we find one without many people, call everyone over, and jump in. I estimate we won't have 25 people, so we'll wait for the launch.
Once there, take out the two middle portals. It would be just too hard with them standing. Once they're down, proceed to either take out a third or just fight back all the enemies while repairing the two side gates and killing them all by any means necessary. Snipe from the towers, halberd from the barricades. The possibilities are endless! Also don't forget about the shifters, but we shouldn't have too much trouble with those.
Bring:
- Hammer
- Axe
- Logs (lots) for repairing the gate. Once they get through, it'll take some effort to get them back out, and we'd be risking the well-being of the void knight.
- Your best everything prone to surviving and slaying
- A dragon battle axe to boost your abilities or some potions
WHEN AND WHERE:
- World 89 (Just to get together to scope worlds - leave that to the events crew that will be attending)
- 2:00PM MDT (1PM PDT, 3PM CDT, 4PM EDT, 9PM UTC, 9PM GMT)
- Saturday, June 30 (Just in time for Canada day!)
Remember, we're trying to keep one or two portals alive to endure the 20 minutes. Try to keep your friends from knowing. We don't want them attacking the portals against our will.
After we endure the 20 minutes ... well, since we're all there, we might as well do a few real rounds. Go wild!
I have never heard of another group doing something like that. 
I didn't see the other side was live as well.
