Glad I could help Just keep in mind, that the reach of a beacon is 20-50 blocks only. The effect will last aprox. 8 seconds
That's the sad thing , when 1.8 comes out I'm already thinking of a funny little way to get up fast whit the slimeblocks, unfortnately I go up very often in the Nether because that's were I mine qaurtz (I like to keep it a bit natural after all). The beacon really helped a bit whit coming up fast!
