Welcome to the Eternal rank!

Almost all skills are eternal here.

Bombers don't die when they explode.

Blockers remain blockers even when
you bomb them. You can only free
them by assigning walkers to them.
All destructive skills go on
indefinitely as long as they have
solid terrain under their feet.
Permanent (athletic) skills behave
as usual.
Stoners however will still kill the
lemming you assign them to.
